Description: Rotary filter cloth (micro cloth filter) is the world's most advanced filters, one of the world now has 700 wastewater treatment plant using the technology. Rotary filter cloth treatment effect, the high water quality, equipment operation and stability, has the world's only water reuse recognized certificate-Title22 certificate. Uses:Rotary filter cloth is mainly used for cooling circulating water, the depth of treated wastewater reuse. As cooling water, recycled water reuse after filtration: water quality SS ≤ 80mg / L below the water quality SS ≤ 20mg / L. Used for advanced treatment of sewage, set in the conventional activated sludge, extended aeration, SBR system, the oxidation ditch system, the trickling filter system, the oxidation pond system, can be used in the following areas: removal of total suspended solids to go with pharmaceutical dosage can remove heavy metals removal . Rotary filter cloth used to filter activated sludge final settling tank effluent, the design quality: the influent SS: 30mg / L (maximum tolerable 80-100mg / L), effluent SS ≤ 5mg / L, Turbidity ≤ 2 NTU, the actual better running water, usually around 1 water turbidity.Work Turntable running the filter into the original water filtration and backwashing sludge simultaneously two relatively independent processes. Two different filters in the same location to complete. a. Raw water filtration: water to be filtered through the inlet pipe from the center of gravity fall into the water distribution device of Rotary dial into the filter tank, then through the filter cloth, so that the effluent suspended solids trapped in the inside of the filter cloth, filter after the water out. b. Backwash: sewage sludge collected in a cloth inside, and gradually form a sludge layer. With the accumulation of sludge on the filter cloth, filter cloth filter resistance increases, filter the water level gradually increased. Pool level by level meter to monitor the change, when to clean the pool level (high level) when, PLC control the initiation of anti-flushing process: filter plate in the center, driven transfer roll to 1 to 3 rev / min speed rotation, while backwash pump starts, backwash pumps filtered water collected in the filter plate and then through the top of the high-pressure injection system umbrella in the top position on the filter cloth to rinse from the outside in, which will accumulate in the inner surface of cloth the dirt removed, and then discharged through the outfall. Backwash frequency and duration adjustable. Backwash, the filter can be continuously filtered. Features ♦ continuous operation; 24 hours of continuous work, without stopping backwash. Continuous backwash filters at the same time. ♦ good effect. Filter cloth aperture of 10 microns, less than 10 microns particle size can be retained (μm) small particles, thus ensuring water quality and water stability. ♦ low backwash water consumption. Backwash water consumption of the total inflow of 1% to 2%, far less than the amount of water required for other filtering device filtering. ♦ head loss. Is generally 0.05 ~ 0.2m. ♦ low operating costs. (Without regard to cost, and removal of pharmaceutical dosage) operating costs of less than 0.01 yuan / ton of water. ♦ installed power is low. ♦ run the fully automated control. Filtration and backwashing entirely by program control, and has multiple protection, management of daily operations without hand. ♦ small footprint. The vertical turntable filter design filter plate, which has a very small area to filter area. ♦ design and construction period is short. Rotary filter the overall modular, design and construction to facilitate quick and easy expansion. These types of filters have been widely used in foreign countries, technology is mature and reliable. In recent years, in the country, there are many cases of successful application, I believe in wastewater treatment, more and more used.
