The semi submerged fiber disc filter is an efficient wastewater deep treatment equipment, mainly used for cooling circulating water, wastewater reuse, and suspended solids removal. Its core structure includes a central drum, a turntable, a backwashing system, and an electrical control system. Fiber filter cloth (made of stainless steel wire or polyester wire) is wrapped around both sides of the turntable, and the minimum filter aperture can reach 10 μ m.
一、 Main features
1. Efficient filtration
When the influent SS is ≤ 80mg/L and the effluent SS is ≤ 10mg/L, combined with chemicals, pollutants such as phosphorus and heavy metals can be removed.
The filter cloth is made of nanofiber material, which has a high flux and is not easy for impurities to adhere. The effective filtration depth is greater than 3mm.
2. Automated operation
The backwashing system automatically cleans the filter cloth through a high-pressure nozzle, and impurities are discharged through the flushing water tank, making operation and maintenance simple.
Designed to withstand impact loads and handle influent with instantaneous peak SS of 80-100mg/L.
3. Structural advantages
Compact equipment, small footprint, and lower head loss compared to sand filters.
Some models adopt a V-shaped inlet water tank design, which pre removes large particle impurities through a tilted filter screen to extend the service life of the filter cloth.
二、 Application scenarios
Cooling water circulation treatment and advanced treatment of secondary effluent from sewage treatment plants.
Suitable for suspended solids removal after activated sludge process, SBR system, oxidation ditch and other processes.
