Filter head Stainless steel filter head 

Product Introduction

Backwash filter head filtration is an important part of water treatment process. When the filter head is operating, with the increase of the amount of sewage intercepted by the filter material layer, the sludge permeability deepens, causing the filter speed to drop, the filter head specification, the filter water level will gradually rise, and the filtered water turbidity will increase. In order to restore the normal operation of the filter and ensure the quality and quantity of effluent, backwashing must be carried out at this time -- the process of backwashing is to feed water from the bottom of the filter plate and impact the filter material layer on the filter plate.

Due to the outdated traditional filter process, high energy and water consumption, high backwashing cost and poor effect, the filter head, filter plate air-water backwashing or filter head plate single water backwashing process of small resistance water distribution system has been commonly used in the design of filter tank. The use of many large, medium and small water plants across the country after construction or transformation has proved that the water distribution system of filter head and filter plate has a series of advantages, such as simple structure, reliable process technology, small head loss, low energy consumption, no dead water area, no clogging and mud accumulation, and convenient construction management. The backwash water volume is only 1/2 to 1/3 of that of the traditional filter tank, and the operation is stable. The water quality and quantity after filtering are significantly improved,

The benefits of the water plant and the society are significant. At present, it has been widely used in various new filter tanks and traditional filter tank transformation projects.
