High Efficiency Rotary Filter for Waste Water Treatment
Fiber turntable filters are mainly used for cooling circulating water treatment and reuse after deep treatment of wastewater. As cooling water, circulating water filtration after reuse: water quality SS ≤ 80mg/L below, water quality SS ≤ 10mg/L. For deep treatment of sewage, set in conventional activated sludge method, delay aeration method, SBR system, oxidation ditch system, drip filter system, oxidation pond system, can be used in the following areas:(1) Removal of total suspended solids (2) Phosphorus can be removed in combination with additives (3) Heavy metals can be removed. Filter cloth turntable filter is used to filter the active sludge final sink out of the water, design water quality: water SS: 30mg/L (can withstand 80-100mg/L), water SS ≤5mg/L, turbidity ≤2 NTU, the general water turbidity in about 1. Features of the filter turntable filter compared to conventional filters: (1) The water quality is good and stable. Filter cloth turntable filter is the use of filter outsourced filter cloth to replace the traditional filter tank sand filter material, filter cloth aperture is very small, can intercept particle size of several microns (m) of small particles, so the water quality and water stability are better than the particle filter. And the conventional filter pool before flushing due to penetration problems poor water quality, after flushing will be due to the residual cleaning water in the filter layer has an impact on the water. In addition, the amount of water filtered also varies with resistance. (2) The design is novel and resistant to impact loads. The filter cloth turntable filter is equivalent to the combination of filter and sedimentation pool, and has the function of draining mud. Large particles of sludge precipitate directly to the bottom of the bucket-shaped pool and do not clog the filter cloth, i.e. unlike ordinary filters: all suspensions (SS) are filtered. Therefore, the filtration cycle is long, the cleaning interval is long, and the hydraulic load and sludge load can be far greater than the conventional sand filter, suspension (SS) load is equivalent to 1.5 times the ordinary sand filter, the filter speed is 50% higher than the ordinary filter tank. Therefore, the filter cloth turntable filter is more resistant to high suspension concentration and the impact of large particulate suspension. (3) The equipment is simple and compa
