Backwash filter housing is a kind of precision equipment that uses the filter screen to directly intercept impurities in the water, remove suspended solids and particles in the water, reduce turbidity, purify water quality, reduce system dirt, bacteria, algae, rust, etc., to purify water quality and protect the normal operation of other equipment in the system. The water enters the self-cleaning filter housing body from the water inlet. Due to the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and automatically discharge the sewage to the sewage valve signal. The principle of the backwash filter housing is that the water enters from the inlet, first passes through the coarse filter screen to filter out the impurities of larger particles, and then reaches the fine filter screen. During the filtering process, the fine filter screen gradually accumulates the dirt and impurities in the accumulated water, forming a filtering impurity layer. Since the impurity layer accumulates at the inner side of the fine filter screen, a differential pressure is formed at the inner and outer sides of the fine filter screen.

The backwash filter housing can make the industrial sewage reach the national wastewater discharge standard, which can effectively protect the environment. At the same time, it can also make the sewage reach the standard that can be reused after treatment. In this way, it can not only solve the problem of sewage discharge, but also realize reuse and save costs. The automatic backwash filter housing is a kind of filter that uses the filter screen to directly intercept impurities in the water, remove suspended solids and particles in the water body, and reduce turbidity, Purify water quality, reduce system dirt, bacteria, algae, rust, etc., to improve water quality and protect other equipment in normal operation. It covers the requirements of various filtering precision from 10um to 3000um, and provides customers with various water filtering equipment.

The features of backwash filters housing are very numerous. I will not give you a brief introduction here. Besides, backwash filters are widely used in food, sugar, pharmaceutical, plastic, automotive industries and other fields. I remind you to pay attention to some matters when installing backwash filters.
