Product Introduction

Rotary fiber disc filter Introduction

The rotary fiber disc filter is mainly used for cooling circulating water treatment and deep treatment of wastewater for reuse. It is used as cooling water and circulating water after filtration: the influent water quality SS≤80mg / L or less, and the effluent water quality SS≤20mg / L.

Equipment characteristics

    (1) The effluent quality is good and stable. Rotary fiber disc filter adopts a filter cloth (the filter cloth material is 316L stainless steel or resin) to replace the sand filter material of the traditional filter pool. Because of the tiny particles of micrometers, the quality and stability of the effluent are better than those of granular filters. The conventional filter has poor water quality due to penetration problems before washing. After washing, the residual cleaning water in the filter layer affects the effluent. In addition, the amount of filtered water also changes with resistance.

    (2) The equipment is simple and compact, with less auxiliary equipment, and the investment of the entire filtration system is low. Rotary fiber disc filter can be continuously filtered during cleaning. The sand filter tank cannot be continuously filtered during backwashing. In order to ensure continuity, it is necessary to set an intermediate storage tank in front of the sand filter tank or use multiple filter tanks to work alternately. Eliminate the need for many backwash tanks, water towers, etc. required by traditional filters. Due to the high backwashing strength of traditional filter tanks, gas-water backflushing requires not only a high-power water pump, a blower, but also two sets of larger diameter pipe-valve systems for gas and water. The whole system is numerous and complicated, and the investment is high. The automatic control system is extremely large and complex.

    (3) The equipment idle rate is low, and the total installed power is low. Because the filter cloth is thin, it is very easy to clean, and the cleaning is very good. When cleaning, the area of the cleaning filter disk is only 1% of the entire filter disk area. The characteristics of cleaning are frequent but the cleaning duration is short (1 time / 1-3 minutes, 10 minutes / time). The overall amount of cleaning water is also less. However, the gas-water backwash pump and blower of the traditional filter tank have many equipments, large and many automatic valves, high power, and a high idle rate.

    (4) The operation is automated, so operation and maintenance are simple and convenient. The filtration process is controlled by a computer, and the interval time and process duration of the cleaning process and the sludge discharging process can be adjusted. There is basically no need for dedicated maintenance and management. The maintenance quantity of Rotary fiber disc filter is small, the mechanical equipment is less, the pump and motor run intermittently, the filter cloth wears less, and the service life of the filter cloth is 10 years. If the filter cloth is blocked due to some reasons, The filter cloth can be easily replaced. For sand filters. If the filter material is clogged, a large amount of cleaning work is required. And it is very difficult to replace the filter material with sand filter.

    (5) The head loss is much smaller than the sand filter. The rotary fiber disc filter is generally 0.2m, and the head loss of the sand filter is generally more than 1.5m. The energy loss of the sand filter tank is large, which increases the operating cost.

    (6) The floor area is much smaller than other filters. Due to the vertical hollow tube design of the filter disc, the small footprint can guarantee a large filtration area, thereby reducing the pool capacity, reducing the amount of materials and earthwork, and significantly reducing the project cost. The filter tank with a daily processing capacity of 10,000 tons covers an area of no more than 20 square meters and a height of 2.35 meters. For technological transformation, the difficulty of insufficient space can be solved.

    (7) It is easier to install than granular filter. After connecting pipe fittings and electrical equipment on site, it can be put into use. And the material filter often needs to install the filter material.

    (8) Short design cycle and construction cycle. The Rotary fiber disc filter is fully equipmentized and can be shipped as a whole. The design and construction are convenient and fast, and the expansion is easy.

    (9) Low endurance requirements for foundations and low investment in equipment foundations.


     It is used for the advanced treatment of sewage. It is installed after the conventional activated sludge method, delayed aeration method, SBR system, oxidation ditch system, trickling filter system, and oxidation pond system. It can be used in the following fields: 1. To remove total suspended solids; 2. Phosphorus can be removed in combination with the addition of chemicals; 3. Heavy metals can be removed.

     The rotary fiber disc filter is used to filter the effluent of the activated sludge final settling tank. The design water quality: Influent SS: 20mg / L (up to 80-100mg / L), effluent SS≤10mg / L, turbidity ≤3NTU, actual operation The effluent is good, generally the turbidity of the effluent is about 1.
