What are the structural characteristics of fiber disc filters

(1) The effluent quality is good and stable.

Fiber disc filter uses filter cloth wrapped around the filter disc instead of traditional sand filter material. The filter cloth has a small pore size and can intercept small particles with a diameter of several micrometers (μ m), so the effluent quality and stability are better than those of granular filter. However, before flushing the conventional filter, the water quality is poor due to penetration issues, and after flushing, the residual cleaning water in the filter layer will affect the effluent. In addition, the amount of filtered water also varies with the change of resistance.

(2) Innovative design, resistant to impact loads.

The fiber rotary filter is equivalent to a combination of filter and sedimentation tank, with the function of sludge discharge. The sludge with large particles settles directly to the bottom of the bucket tank without clogging the filter cloth, unlike a regular filter: all suspended solids (SS) must pass through the filter material. Therefore, the filtration cycle is long, the cleaning interval is long, and the hydraulic load and sludge load that can be borne are much greater than those of conventional sand filters. The suspended solids (SS) load is equivalent to 1.5 times that of conventional sand filters, and the filtration speed is increased by 50% compared to conventional filters. Therefore, the fiber disc filter is resistant to high suspended solids concentration and the impact of large suspended particles.

(3) The equipment is simple and compact, with few auxiliary devices, and the investment in the entire filtration system is low.

The fiber disc filter can be continuously filtered during cleaning. When backwashing the sand filter, it cannot filter continuously. To ensure continuity, an intermediate water storage tank needs to be set up in front of the sand filter or multiple filters need to work alternately. The fiber rotary filter adopts a small water pump for negative pressure suction and automatic cleaning of filtered water, eliminating the need for backwash water tanks, water towers, and other traditional filters.
