What is a backwash filter?

What is the backwash filter? Compared with the ordinary filter, the backwash filter has the function of automatic sewage discharge. For example, the ordinary filter intercepts impurities through the filter screen and needs to be cleaned regularly, but the backwash filter has The function of automatic identification of impurities and automatic exclusion.

1. The backwash filter is a filter that directly intercepts impurities in the water, removes suspended solids and particulate matter in the water body, reduces turbidity, purifies water quality, and reduces system fouling, algae, rust, etc., to purify water and protect the system. Precision equipment where other equipment works normally. The water enters the self-cleaning filter 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 by signalling the sewage valve.

2. The automatic backwash filter overcomes many shortcomings of traditional filtration products, such as small dirt holding capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the filter status cannot be monitored. It has the ability to filter raw water and automatically filter the filter element. The function of cleaning and discharging sewage, and the system provides uninterrupted water supply when cleaning and discharging, and can monitor the working status of the filter, with a high degree of automation. Covering the needs of various filtration precisions from 10um to 3000um, providing customers with various water filtration equipment.


3. The automatic backwash filter can be used for the filtration of industrial water, seawater, food and pharmaceutical industry wastewater and circulating water, as well as the filtration of chemical liquid, waste oil, liquid raw materials, etc. In the metallurgical industry, petrochemical industry and power plant water supply and drainage and circulating water systems and media filtration involving liquid, the application of automatic backwash filters is also increasingly widespread. The continuous casting water system, blast furnace water system, The high-pressure water descaling system, emulsion system, closed water circulation system, and liquid media filtration system for hot rolling use a large number of automatic backwash filters.

The device has been debugged before leaving the factory, and the user can directly run it when using it. When the operating parameters of the equipment cannot meet the user's requirements, the user can adjust the parameters according to the actual working conditions, and select manual control and automatic control to work accordingly. When running for the first time, the following steps should be followed:

Today, I introduced the backwash filter. Do you understand? The backwash filter has the function of automatic sewage discharge.
