The fiber turntable filter is a new type of filtration equipment used for sewage treatment. It adopts a continuous self-cleaning mode and achieves efficient physical filtration through fiber filter cloth. It is widely used in the fields of municipal sewage advanced treatment, industrial water purification and reclaimed water reuse. Its core structure consists of a fan-shaped filter plate, a driving motor, a central water collection barrel and a backwash device. It uses a PLC automatic control system to realize the full process management of filtration, cleaning and mud discharge.
The equipment operates based on the principle of gravity flow. The sewage is filtered from the outside to the inside through the filter cloth and then discharged through the hollow tube. Backwashing uses negative pressure suction technology to periodically remove sludge on the surface of the filter cloth without shutting down. Compared with traditional sand filters, it has the advantages of stable effluent quality (SS ≤ 10mg/L), low operating costs (water and electricity consumption per ton ≤ 0.004 yuan), and small floor area (10,000-ton treatment scale ≤ 20m²). At the same time, traditional structures such as blower rooms are omitted, reducing energy consumption and investment costs. The filter cloth is made of nylon or polyester fiber, with a pore size ≤10 microns and a service life of 3-10 years. It supports modular installation and rapid maintenance.
In today's society, advanced technology is the primary productive force, and advanced technology will inevitably eliminate backward technology. Fiber turntable filter technology is a masterpiece in this era of sewage treatment. Its most notable features are low operating costs, good and stable effluent quality, and a very small footprint. Compared with previous traditional processes, it has the following advantages:
1. The effluent water quality is good and stable, reaching the national Class A standard. The backwashing intensity is 333L/ms and the backwashing frequency is high, once every two hours to prevent the growth of green algae and prevent the filter cloth from clogging or hardening.
2. The operating cost of the fiber turntable filter is very low. The operating cost of processing one ton of water is only 0.004 yuan (4 centimeters), while the operating cost of traditional processes (V-type filter, D-type filter, fiber bundle/ball filter) is 0.2-0.3 yuan. Taking 10,000 tons of water as an example, it can save 500,000-700,000 yuan a year.
3. Compared with the traditional process, the fiber turntable filter eliminates the need for civil construction such as the blower room, lifting pump room, chlorination room, clear water tank, sedimentation tank, etc. It occupies a very small area. The area of 10,000 tons of water is only 15m, which is 1/6-1/7 of the traditional process.
4. The fiber turntable filter eliminates many structures, valves, pipelines, etc., making the maintenance and repair of the equipment simple and convenient, and the operation is highly automated, so there is no need for special personnel to supervise, and the labor intensity of workers is greatly reduced.
5. Compared with previous traditional filters, the fiber turntable filter eliminates the need to add chlorine beforehand, which not only reduces operating costs, but also avoids unsafe risks for workers (high CLO2 concentrations may cause flash explosions, endangering workers' lives).
The fiber turntable filter technology is quite mature and has been successfully used in hundreds of sewage treatment plants across the country. This technology has been recognized by more and more companies across the country.
