Automatic backwash pre filter tap water purifier

Automatic backwash pre filter is a precision equipment that uses a filter screen to intercept impurities in water (such as suspended solids, particulate matter, etc.) and has automatic backwash function. Its core structure usually includes high-quality carbon steel cylinder, stainless steel wedge-shaped filter screen, butterfly valve, and sewage device components. During operation, impurities are trapped on the surface of the filter when water flows through it; When the filter becomes clogged and reaches a certain pressure difference or time, the system automatically starts a backwash program, which restores the filtering performance of the filter by changing the direction of water flow or using mechanical devices to remove impurities.

5. Stable operation and low maintenance cost: The filter has a long service life and does not require frequent replacement; The backwashing process does not require shutdown to ensure continuous operation of the system.

6. Easy to operate: Equipped with an intelligent control system, users can easily set parameters and monitor device operation status through the interface.

2. Automotive manufacturing: widely used in painting production lines and engine manufacturing water treatment systems.

3. Power plant: used for precision pretreatment of high-purity water preparation for boilers, filtration of cooling water and sealing water for generators, and side filtration treatment when the system consumes a large amount of water.

4. Chemical industry: In the circulating water plant, side filtration treatment can be carried out, and single or multiple machines can be connected in parallel for main treatment, reducing the filter load and saving costs.

5. Metallurgical industry: used for continuous casting water, high-pressure phosphorus removal water, clean circulating water, turbid circulating water filtration, cooling water full filtration, side filtration, and nozzle protection.

6. Power industry: used for steam turbine cooling water filtration, grey water recovery filtration, dust reduction nozzle protection, cooling tower water full filtration and side filtration, etc.

7. Other fields: Suitable for water treatment systems in industries such as construction, petroleum, textiles, papermaking, food, sugar, pharmaceuticals, plastics, etc., to prevent blockages in cooling water systems and ensure normal system operation.
