High-pressure backwash screen filter

High-pressure backwash screen filter is suitable for high-salinity water such as seawater and salt lake water. It offers high corrosion resistance, high efficiency, and strong anti-corrosion properties, with a maximum processing capacity of up to 4000 t/h.

 Product Features:

Compared to other similar filters, the Qinhuang Haiwo brand high-pressure backwash screen filter has the following key features:

1. The Qinhuang Haiwo brand seawater filter uses a high-precision, high-strength 2507 duplex stainless steel (or alloy) composite screen. Through high-pressure backwashing at 1.7-2.0 MPa, the screen is cleaned efficiently and thoroughly, fully restoring its initial state.

2. The seawater backwash filter has an automatic retrieval function. It automatically performs sewage discharge and high-pressure backwashing based on retrieved data, capable of handling unstable water quality fluctuations. It operates fully automatically without the need for manual intervention.

3. The control system is highly responsive and precise, featuring multiple setting functions for differential pressure, time, and manual operation. It allows flexible adjustment of backwash differential pressure or time settings according to different water sources and filtration accuracy requirements.

4. Backwashing does not interrupt normal water production, ensuring continuous, stable, and reliable operation.

5. The backwashing process is short, with backwash water consumption being only 0.001~0.002% of normal water production, saving water, electricity, and energy.

6. The structural design is compact and rational, with few vulnerable parts, no consumables, low operating and maintenance costs, and simple operation and management.

7. It can be installed vertically or horizontally based on the installation site conditions, offering flexibility and convenience.
