Cloth turntable filter; 
 Company development and production of cloth rotating filter has been made the country a number of inventions and utility model patents with completely independent intellectual property rights, cloth turntable filter technology and quality are the leading domestic level, cloth turntable filter has been in a number of large sewage treatment works has been applied with good results. 

 Cloth dial filters are mainly used for cooling circulating water treatment, wastewater depth treatment and reuse. Reuse: water as cooling water, recycled water filtered water quality of the SS ≤ 80mg / L, the effluent SS ≤ 10 mg / L,. For the depth of sewage treatment, set in the conventional activated sludge, extended aeration and SBR system, oxidation ditch system, the trickling filter system, after the oxidation pond system can be used in the following areas: (1) removal of total suspended solids ② combination dosing agent can go to phosphorus removal ③ can remove heavy metal. Filter cloth turntable filter for activated sludge final sedimentation tank effluent design Water Quality: Influent SS ≤ 20mg / L (can withstand up to 80-100mg / L), the effluent SS ≤ 5 mg / L, and turbidity <2 NTU and the actual running water quality, general water turbidity. 
 Characteristics compared with conventional filter cloth turntable filter: 

 (1) water quality is good and stable. Cloth turntable filter is a filter disk outsourcing cloth instead of the traditional filter sand filter, filter cloth aperture is small, may withhold the particle size of several microns (μm), small particles, water quality and water stability better than the pellet filter. Conventional filter washing prior to penetration, poor water quality, the rinse water after washing the filter layer remnants of an impact on the water. Another filter of the water also changes with the change of resistance. 
 (2) innovative design, resistance to shock loading. Cloth turntable filter is equivalent to a combination of filters and sedimentation tanks, with the function of the mud. Large particles of sludge by direct precipitation to the bucket-shaped bottom, will not clog the filter cloth, unlike the ordinary filter: all suspended solids (SS) must go through the filter. Filtration cycle, the cleaning interval length, and can withstand the hydraulic load and sludge loading is much larger than the conventional sand filter, the load of suspended solids (SS) is equivalent to 1.5 times the ordinary sand filter, filter speed ratio ordinary filter increased by 50%. Cloth dial filters are more resistant to the impact of suspension of high concentration and large particles of suspended solids. 
 (3) The device is simple and compact, ancillary equipment, low investment in the entire filtration system. Cloth turntable continuous filter cleaning filter. Sand filter backwash can not be continuous filtration in order to ensure continuous, before the sand filter located intermediate storage tank or multiple filters work alternately. Cloth turntable filter with automatic cleaning small pump vacuum suction filtered water, eliminating many of the traditional filter backwash pool, water tower. Traditional filter backwash strength, gas and water recoil not only need high-power water pumps, blowers, air-water two large diameter pipe valve system. The entire system are many and complex, high investment. The automatic control system is extremely large and complex. 
 (4) low idle time of equipment, the total installed power is low. The cloth is thin, very easy to rinse clean, very efficient cleaning, cleaning, cleaning of the filter plate size is only 1% of the entire area of ??the filter plate. Cleaning is characterized by frequent cleaning but short duration (1 / 60-120, 1 minute / second). The overall cleaning and less water. Traditional filter the air-water backwash pump and blower equipment, automatic valves, multi-power, and idle high. 


 (5) run the automation, and thus the operation and maintenance is simple and convenient. The filtering process is controlled by computer, adjustable vacuum suction cleaning process and mud of the interval and the process lasted. Basically do not need someone to maintenance and management. Overhaul of the cloth turntable filter. Cloth turntable filter machinery and equipment less the intermittent operation of the pump and motor, wear small cloth, filter cloth is easy to replace, if for some reason caused by the filter cloth clogging can easily replace the cloth. For the sand filter, filter clogging, you need a lot of cleaning workload. And the sand filter replacement media is very difficult. 
 (6) the head loss is much smaller than the sand filter. Cloth dial filters are generally 0.2m, sand filter head loss is generally 1.5m. The head loss of the sand filter tank is higher than 5m, energy loss and increase operating costs. 
 (7) covers an area much smaller than the other filter. Vertical hollow tube design of the filter plate, a small footprint to ensure a large filtration area, thus reducing the pool capacity, reducing the amount of material and Earthwork, significantly reduced the project cost. Processing 10,000 tons of filters, covers an area of ??not more than 20 square meters, the height of 3.3m. Technological innovation, we can solve the difficulties of not enough space. 
 (8) cloth turntable filter pellets filter easy to install. Site connecting pipe fittings and electrical equipment can be put into use. Pellets filter often need to install the filter. 
 (9) the design cycle and a short construction period. The filter cloth turntable overall equipment can be a whole shipment, design and construction is easy and quick; and expansion easy. 
 (10) to base endurance requirements, equipment foundation investment. 
 Particularly suitable for upgrading the sewage treatment plant has been built, can be resorted to water from a B to an A
