Today several sets of Internal Feed Drum Filter Screen were Delivered to Mexico.
Internal Feed rotary drum screen is an efficient solid-liquid separation equipment, mainly used to remove suspended particles (>0.2mm) in water, and is widely used in industrial wastewater, municipal wastewater, aquaculture and other fields. The following are its core points:
1. Working principle and structure of Drum Filter
Workflow: Sewage enters the rotating mesh tube uniformly through the buffer inlet, and is filtered through the gaps of the mesh tube. Impurities are trapped in the tube and discharged with the spiral rotation of the slag guide. The filtered water flows out of the mesh tube for 12 days.
Core structure:
Drive device: Chain drive, high efficiency.
Mesh tube: made of stainless steel material, with adjustable aperture of 0.2-2mm.
Backwash system: High pressure water automatically flushes the filter screen to prevent blockage.
Anti overflow design: Two side baffles prevent sewage from splashing.
2. Performance advantages of Rotary Drum Filter
Efficient processing:
The processing capacity reaches 80-1500m ³/h, suitable for high flow scenarios.
Suspended solids removal rate>80%, algae removal rate 40-70%.
Stable and low consumption:
The noise level is below 58dB and the operation is stable.
Low energy consumption, with a main motor power of 0.75-3kW.
High degree of automation:
Continuous operation, automatic slag discharge, no need for dedicated personnel to be on duty.
3. Main application scenarios
Industrial wastewater:
Fiber recovery from papermaking/textile wastewater (recovery rate>98%).
Solid liquid separation of slaughter and food processing wastewater.
Municipal Administration and Water Treatment:
Pre treatment of sewage plants, replacing sedimentation tanks.
Raw water filtration in water treatment plants (excluding algae and plankton).
Aquaculture:
Purification of circulating water system to remove fecal residues.
