Today one set of Dissolved Air Flotation were delivered to Sri Lanka. Air flotation equipment is a water treatment device that uses microbubbles to attach suspended particles and utilizes buoyancy to achieve solid-liquid/liquid-liquid separation. The core principle is to allow air to enter the water in the form of highly dispersed microbubbles, so that pollutants have a lower density than water and float to the surface, thereby achieving purification or separation. working principle Taking dissolved air flotation as an example: Raw water is mixed with dissolved water, and microbubbles adhere to the surface of suspended particles. The density of the bubble particle composite is lower than that of water, and it rises to the water surface with buoyancy to form floating debris. By using a scraper to remove floating slag, solid-liquid separation can be achieved, and the effluent can be discharged or reused in compliance with standards. Core application scenarios Municipal/water supply field: Separate fine suspended solids, algae, and microorganisms from surface water to improve the pre-treatment quality of water plants. Industrial wastewater treatment: Paper industry: Recycling pulp from wastewater and treating wastewater from paper making (when the influent COD is ≤ 3000mg/L, the effluent COD can be controlled between 50-200mg/L). Chemical/Leather/Pharmaceutical: Treat high concentration organic wastewater, reduce environmental load, and ensure water quality safety. Food processing/brewing: treating high suspended solids wastewater to promote clean production. Sludge treatment: replacing secondary sedimentation tanks to achieve sludge concentration and dewatering, reducing subsequent treatment costs.

The sludge dewatering machine is the core equipment in the sewage treatment process, and its core value lies in the efficient solid-liquid separation of sludge with a moisture content of over 95%, achieving reduction, stabilization, and resource utilization, laying the foundation for subsequent disposal processes such as incineration, landfill, and land use. A sewage treatment plant with a daily processing capacity of 100000 tons can produce hundreds of tons of wet sludge per day, and the cost of dewatering accounts for 20% -30% of the total treatment cost. Working principle and core performance Mainstream equipment integrates multiple processes such as negative pressure adsorption, gravity settling, and roll extrusion to achieve continuous automated operations Stacked screw type: By dynamically squeezing the spiral shaft and the dynamic and static ring plates, the sludge moisture content is reduced from 95% to below 80%. The daily processing capacity of a single unit can reach 50-200 tons, and the efficiency is increased by 40% compared to traditional belt conveyors. Plate and frame type: In a sealed state, the sludge is driven by a high-pressure pump to be extruded through a filter cloth, achieving solid-liquid separation. Centrifugal: Using the centrifugal force generated by high-speed rotation, the water in the sludge is thrown out to achieve rapid dewatering. The moisture content of the filter cake of qualified equipment can be stably controlled at 9% -19% (meeting the requirements of landfill and incineration), and the cleanliness of the separated water is high. The recycling rate can reach 68%, and a single person can be on duty, reducing labor input by 32%. The overall power consumption of the machine is low, and the maintenance cycle can reach more than 30 days. Municipal sewage treatment plant (domestic sludge) Industrial wastewater treatment (sludge from industries such as printing and dyeing, papermaking, electroplating, petrochemicals, pharmaceuticals, and food) River dredging and sediment dewatering, drilling mud treatment, building materials factory mud dewatering, etc Key points of selection Mud analysis is a prerequisite: the viscosity and particle composition of sludge from different sources (domestic sludge vs oily/heavy metal industrial sludge) vary greatly, and it is necessary to conduct mud sample analysis and small-scale testing first to determine the appropriate model and flocculant type. Matching processing capacity and site: Single machine processing capacity covers 6-225m ³/h, and compact architecture equipment is more suitable for sewage stations with limited space. Automation and stability: Prioritize equipment with automatic correction, automatic cleaning, and PLC control to reduce manual labor intensity and ensure 24-hour continuous operation.

Today hundreds cube meters of MBBR Media were delivered to Philippines. With the increasingly severe global water shortage problem, sewage treatment technology is constantly innovating and developing. As a core component of biofilm wastewater treatment technology, mbbr filter media play an irreplaceable role in improving treatment efficiency and reducing operating costs. This article will systematically introduce the working principle, main types, application status, and future development trends of biological fillers. Biological fillers (k1 media,k3 meida,k5 media)provide a carrier surface for microorganisms to attach and grow, forming a stable biofilm system. When sewage flows through the packing material, pollutants are adsorbed and degraded by the biofilm, thereby achieving water purification. Its core mechanism includes: Physical adsorption: The pores on the surface of the filler adsorb suspended solids and colloidal substances Biodegradation: attached microorganisms decompose organic pollutants Mass transfer enhancement: cutting bubbles to improve dissolved oxygen utilization efficiency The required range of indicators is important, with a specific surface area of 13.6-25.5 m ²/kg, which determines the amount of microbial attachment. The porosity of about 40% affects water flow resistance and mass transfer efficiency. Hydrophilic surfaces with positive charges promote microbial fixation, mechanical strength, compressive strength ≥ 5.78 MPa, ensuring long-term operational stability, chemical stability, acid and alkali resistance, and adaptability to different water quality environments. MBBR suspended packing adopts a hollow structure, with anaerobic and aerobic bacteria growing inside and outside respectively. It can move freely in the reactor without dead corners, making it particularly suitable for sewage treatment and fluidized bed processes. The application of biological fillers in urban sewage treatment plants is very mature, which can effectively remove pollutants such as COD, BOD, and ammonia nitrogen, and the effluent quality is stable and meets the standard.

Today several pallets of Polyester Fiter Ball were delivered to Sweden. Biological filter is a type of water treatment filter material formed by tying polymer fiber filaments into a spherical shape. It has advantages such as large interception capacity, low backwash water consumption, and long service life. It is widely used in deep purification of sewage treatment, industrial circulating water, and oily wastewater treatment. Fiber ball filter material is a key filtration material developed to meet increasingly strict water quality standards and the demand for water resource recycling. With the increase in sewage reuse rate and the growing demand for high-purity water in industries such as electronics, chemical, and power, traditional sand filtration is no longer able to meet precision requirements. Fiber balls, with their variable pore structure and high specific surface area, have become an upgraded alternative solution. Core features and performance parameters Good elasticity, acid and alkali resistance, and a porosity of up to 96%. The loading height is usually 120 cm, and it naturally compresses by about 30 cm after entering the water. The filtration speed range is wide (20-85 m/h), and the interception capacity reaches 6-35 kg/m ³. The backwashing water consumption only accounts for 1% -2% of the periodic filtration water consumption, with a lifespan of over 10 years. Ordinary Bio Filter Media are mainly made of polyester/polypropylene, while modified fiber balls undergo surface hydrophilic treatment, significantly improving their adsorption rate for oil substances (up to 98%). Fiber balls are not a single product, but a filter material system that covers multiple technological generations such as ordinary fiber balls, modified fiber balls, fiber bundles, and comet shaped fiber filter materials; When selecting, it is necessary to consider the quality of the raw water (such as whether it contains oil), effluent standards (such as reuse/discharge), and operation and maintenance conditions (whether automatic backwashing is supported).

Today several sets of  Internal Feed Rotary Drum Filter Screen were delivered to Russia. Drum Filter Internal Feed is a solid-liquid separation equipment that allows sewage to enter from the inside of a drum, filter through stainless steel microporous screens, and flow out through the gaps in the drum wall. It achieves continuous mechanical separation of "internal inlet and external filtration" and is widely used for suspended solids interception and water purification in industries such as aquaculture, papermaking, and food. Internal inflow "refers to sewage that does not directly impact the outer surface of the filter screen, but flows smoothly and evenly into the rotating drum through a buffering water tank or overflow weir water distributor, and then passes through the gaps of the filter screen to discharge clean water under the action of gravity and shear force; And the solid particles are trapped in the cylinder and transported to the slag discharge end with the spiral guide plate for automatic discharge. This design significantly reduces head loss (only 0.2-0.3 m), avoiding the problems of blockage and high energy consumption caused by traditional external water inlet methods. Working principle and structural key points of rotary drum filter screen Inlet method: Sewage flows through the inlet pipe → buffer tank/overflow weir → evenly distributed on the inner wall of the rotating filter cartridge, forming a stable water film; Filtering mechanism: The water flow generates relative shear motion with the rotating filter cartridge, and the stainless steel mesh with a mesh size of 80-200 mesh per square inch (approximately 75-150 μ m) intercepts suspended particles of ≥ 0.2 mm; Slag discharge method: The spiral guide plate inside the cylinder rolls and pushes the trapped waste to the outlet end, where it falls into the slag collection tank; Self cleaning guarantee: The external high-pressure backwash pipe (3 kg/cm ²) sprays in a fan shape, unclogging the filter screen in real time to ensure continuous operation without interruption. The essence of an internal water inlet microfilter is a drum type screen separation device with "internal inlet and external filtration". Its core value lies in achieving efficient interception of small suspended solids above 0.2 mm with low head loss, coupled with fully automatic backwashing, which is particularly suitable for industrial and aquaculture scenarios that require continuous operation, high water quality requirements, and focus on operating costs. If used in aquaculture, it can significantly reduce turbidity and ammonia nitrogen load caused by algae, residual feed, feces, etc.

With a high oxygen utilization rate of 0.112-0.185 kgO ₂/h · m, self closing anti backflow design, and a membrane lifespan of 5-8 years, it has become the main aeration solution for municipal and industrial wastewater biochemical treatment. SILICONE TUBE DIFFUSER has long relied on imports and has now achieved domestic substitution, with performance reaching international standards. It is widely used in organic industrial wastewater treatment scenarios such as sewage treatment plants, aquaculture, printing and dyeing/pharmaceuticals. Its core value lies in: efficient oxygenation (producing 1-3 mm bubbles through micropores), energy saving and consumption reduction, anti blocking and anti backflow, and convenient installation and maintenance (such as lifting type non emptying maintenance). Analysis of Structure and Working Principle Composition: Composed of EPDM rubber diaphragm, inner lining support tube (Φ 63-69mm), clamp, and gas supply pipeline. Aeration mechanism: During gas supply, the membrane bulges and the micropores (1.5 mm, 2 × 2.5 mm spacing) open to release 1-3 mm bubbles; After the gas is stopped, the diaphragm shrinks elastically, and the 15 mm non porous area is automatically sealed to prevent sewage backflow.

Today two sets of Internal Feed Rotary Drum Filter Screen were delivered to Brazil. Drum Filter Internal Feed Screen is an automated equipment that injects sewage from the inside of a rotating filter cartridge by gravity/pump pressure, and achieves solid-liquid separation through stainless steel or engineering plastic filters. The mainstream model has a filtration accuracy of ≥ 0.2mm and is suitable for aquaculture, industrial wastewater, and reclaimed water reuse scenarios. Drum Filter (also known as Rotary Drum Filter or rotary drum filter screen) is a mature and efficient solid-liquid separation equipment in the current water treatment field, widely used in the pretreatment process of aquaculture wastewater, food processing, chemical industry, papermaking and other industries. Its core design is different from the "external inlet" model - sewage is evenly distributed inside the filter cartridge, suspended particles (≥ 0.2mm) are intercepted by the filter screen, clean water is discharged through the screen, and the dirt is pushed to the slag discharge outlet by the slag guide screw. This structure can better maintain solid integrity, improve retention rate, and support fully automatic backwashing and anti blocking. Core structure and working principle Water inlet method: divided into two mainstream modes. Post pump pressure type: The water pump is directly connected to the inlet, but it is prone to crushing soft impurities such as fish manure, reducing filtration efficiency and slightly increasing energy consumption. Self flowing (gravity type): The recommended solution relies on the natural inflow of water level differences, retaining the original form of impurities, saving energy, and having a higher retention rate. The system needs to adopt an underground/stepped layout. Key components: Rotating filter cartridge (material: 304/316 stainless steel or UPVC/HDPE engineering plastic). Built in slag guide screw (synchronous rotation, forced discharge). Backwash spray system (to prevent filter clogging). Anti overflow board and automatic control system (including real-time display of turbidity, flow rate, etc. on LCD screen) Selection and application suggestions Priority selection from flow type and stainless steel body: Especially in high organic load scenarios such as aquaculture and slaughter wastewater, it can significantly improve the retention rate of large particles such as fish manure, hair, and residual bait. Pay attention to backwash configuration: Without this function, it is easy to cause clogging of the filter screen, which affects the stability of continuous operation. Customized requirements are clear: external dimensions, filtering area, motor power, and control interface (such as whether PLC networking is required) should be communicated with the manufacturer's technical team in advance. Attention to matching: It is recommended to use it in conjunction with a sedimentation tank/sieve bin to form a two-stage pretreatment of "gravity settling+microfiltration", which extends the service life of the microfiltration machine.

Today one set of Internal Feed  Drum Filter Screen was Delivered to Australia. Rotary drum filter screen is a solid-liquid separation device. Sewage enters from the inside of the drum and is filtered through a microporous screen (usually 60-200 mesh/square inch). The clean water is discharged through the gaps in the drum wall, and the suspended particles (≥ 0.2mm) intercepted are pushed by the slag guide screw to the slag outlet and discharged as the drum rotates. Compared to the external inlet type, it has a more uniform water distribution, stronger resistance to impact loads, and comes with a built-in backwash device to prevent blockage. It is widely used in aquaculture, papermaking, food processing, and urban sewage treatment. Drum filter screen, also known as drum type microfilter or rotary microfilter, is different from external inlet type. Its sewage enters from the inside of the drum and is filtered from inside to outside through a sieve, which is more conducive to intercepting small particles and reducing the risk of blockage. This technology has been maturely applied in fields such as seawater aquaculture circulating water, papermaking white water recovery, and deep treatment of urban sewage. Core structure and working principle Main components: water inlet tank, stainless steel drum (including 60-200 mesh/square inch microporous screen), motor drive device, fully automatic backwash pump, buffer distribution box, slag guide screw and slag collection tank. Operation process: 1. The sewage rises steadily to the filtered water level through the buffer distribution box. 2. Purified water enters the water storage box through the gaps in the sieve, and solids are trapped in the net. When the filter screen accumulates and causes the water level to rise to the set high level, the liquid level system automatically starts the backwash pump and drum motor. 4. High pressure water fan-shaped spray cleans the filter screen, and the dirt falls into the slag collection tank and is discharged. Rotary Drum Filter, with its four advantages of compact structure, high automation, low head loss, and strong corrosion resistance, has become a key equipment for SS and algae pretreatment in closed circulating water systems (such as factory aquaculture and paper white water reuse). When selecting, special attention should be paid to matching the processing capacity, mesh size (determining the retained particle size), material grade (especially for seawater conditions), and compatibility with the control system.

Today hundreds cube meters of MBBR Media were delivered to Philippines. Mbbr filter media are the core carriers used in circular aquaculture and wastewater treatment to promote microbial attachment and growth, and achieve water purification. Their performance directly affects the treatment efficiency and stability of the system. In circular aquaculture and sewage treatment systems, pollutants such as ammonia nitrogen and organic matter in water rely on microbial degradation. However, freely floating microorganisms are easily washed away by water currents or destroyed by disinfectants. The function of biological fillers is to provide stable habitats for these "water purification heroes", form biofilms, and continuously and efficiently decompose pollutants. When selecting high-quality MBBR Media(k1 media,k3 meida,k5 media), attention should be paid to the following points: High specific surface area: provides more space for microbial attachment and improves treatment efficiency. Safe material: Select non-toxic, corrosion-resistant, and heavy metal free materials (such as PP) to ensure that they are harmless to aquaculture organisms or the environment. Good film-forming properties: Materials with strong hydrophilicity and moderate surface roughness are more conducive to initial microbial attachment. Structural rationality: High porosity, three-dimensional flow design can prevent blockage, suitable for long-term operation. Economic considerations: Taking into account both price and lifespan assessment costs, for example, ceramics may be expensive but durable, while plastics offer higher cost-effectiveness. Biological fillers significantly enhance microbial purification capabilities by providing a large specific surface area and stable environment, making them an indispensable key component of modern water treatment systems. Choosing the appropriate type (fixed bed or mobile bed), material, and structure based on the application scenario can significantly improve system efficiency and reduce operation and maintenance costs.

MBBR Media Delivered to Southeast Asia. MBBR Media(k1 media,k3 meida,k5 media) are key materials used in circular aquaculture and wastewater treatment to promote microbial attachment and growth, and achieve water quality purification. They provide a large specific surface area for beneficial microorganisms such as nitrifying bacteria to colonize, forming biofilms and efficiently degrading pollutants such as ammonia nitrogen and organic matter. In circular aquaculture or sewage treatment systems, physical filtration alone cannot effectively remove dissolved harmful substances (such as ammonia nitrogen). Microorganisms can convert these pollutants into harmless substances, but they are difficult to survive stably in water. The function of biological fillers is to create a "safe haven" for microorganisms, allowing them to gather in large quantities and continue to function. How to choose high-quality biological fillers? Matching purposes: The breeding system prioritizes safe and non-toxic materials; Industrial wastewater treatment focuses on corrosion resistance and mechanical strength. The higher the specific surface area, the stronger the processing capacity per unit volume, saving land. Check hydrophilicity: Fillers with good hydrophilicity, such as polyurethane with amino or carboxyl groups, can accelerate microbial biofilm formation. Qualification verification of suppliers: Select enterprises with research and development capabilities, such as Nanjing Kehuan Biological Filler Co., Ltd., which focuses on the research and development of activated carbon and zeolite filter materials, and Sujing Group, which provides customized biological ropes, biomimetic aquatic plants, and other new fillers. Conclusion: Choosing the right filler can achieve twice the result with half the effort The selection of mbbr filter media should be balanced based on specific application scenarios, including specific surface area, material safety, structural stability, and operating costs. The current trend is towards the development of mobile bed fillers with high specific surface area, strong hydrophilicity, and long lifespan, such as K-series suspension balls and polyurethane carriers, which have become mainstream choices. If pursuing fast start-up and low operation and maintenance costs, it is recommended to use MBBR process with k1 media, k3 media, k5 media. If it is for ecological restoration or low disturbance environments, flexible fillers such as biomimetic aquatic plants and biological ropes are also worth trying.

Today thousands of Fine Bubble Diffusers were delivered to Chile. The Fine Bubble Disc Diffuser indeed plays a crucial role in water treatment, serving as key equipment for efficient oxygenation. By injecting air or oxygen into water, 12 inch disc diffuser increases the dissolved oxygen content, promoting the degradation and oxidation of organic matter in the water, thereby achieving water purification. 8 inch disc diffuser is widely used in sewage treatment plants, drinking water treatment plants, and industrial wastewater treatment systems. In sewage treatment plants, aerators are typically employed in the activated sludge process, where air is introduced into the wastewater to facilitate microbial degradation of organic matter, thus purifying the sewage. In drinking water treatment plants, aerators are used to enhance dissolved oxygen levels and improve water quality. Meanwhile, in industrial wastewater treatment systems, aerators are utilized to intensify the oxidation and decomposition of harmful substances in the wastewater, thereby reducing pollutant concentrations. Development trend: Some 9 inch disc diffuser have integrated precise control technology, which can automatically adjust the aeration amount by monitoring parameters such as dissolved oxygen and COD, improving energy efficiency. Patent innovation: Enterprises have developed aeration devices that combine photovoltaic power, suitable for off grid or energy-saving water treatment systems When choosing an aerator, the following factors should be considered comprehensively: Treatment of water quality and load (such as sludge concentration, suspended solids content) Do you need uninterrupted water maintenance Oxygen transfer efficiency and operational energy consumption requirements Installation space and layout density
