Today, a set of high-efficiency dissolved air flotation system (daf system) machines produced by GNGEP was successfully sent to the sewage treatment project of Serbia processing enterprises. This device adopts internationally leading nano scale microbubble generation technology, with a single machine daily processing capacity of 3000m ³. It can achieve a suspended solids (SS) removal rate of ≥ 95% and an oil separation efficiency of ≥ 90%, providing a key solution for the pretreatment of high concentration organic wastewater.
Technical highlights:
Precise separation: Multiphase flow control technology combined with adjustable release device, microbubble particle size ≤ 30 μ m, achieving efficient capture of colloids and emulsified oil;
Intelligent control: equipped with PLC+IoT dual control system, real-time monitoring of dissolved gas pressure (0.3-0.5MPa), water level and scraping frequency, supporting remote fault diagnosis.
Long term durability: Made of all 304 stainless steel structure with EPOXY anti-corrosion coating, suitable for harsh environments with pH 2-12, with a lifespan of over 15 years.
The daf dissolved air flotation can be widely used for the pretreatment of high turbidity wastewater in industries such as petrochemicals, printing and dyeing, and food processing, and is particularly suitable for complex water quality containing floating oil, colloids, and fiber suspensions.
This dissolved air flotation machine will be used to treat food wastewater containing animal and plant oils and proteins. Customer feedback: "The stability of the air flotation system operation far exceeds expectations, and after pretreatment, COD drops by 60%, significantly reducing the burden on subsequent biochemical processes. ”
