Automatic Backwash Filtration System · High-End Industrial Fluid Purification Solution

Core technology metal filtration, integrating four core components, fully automatic operation, suitable for extreme working conditions, efficiently intercepting impurities, energy-saving and durable.

Core Configuration · Benchmarked Against International Standards

  • Metal Filter (Core): Equipped with  sintered powder filter elements, made of high-quality materials such as 316L stainless steel, formed by high-temperature sintering.

    Pore size ranges from 0.1μm to 100μm, interception rate over 99.9%, temperature resistance from -200 to 600, pressure resistance ≥10MPa, renewable and reusable for 3-5 years.

  • Backwash Valve: Pneumatic/electric stainless-steel material, fast response, zero leakage, backwash water consumption only 1%-3%, highly water-saving.

  • High-Precision Pressure Gauge: Accuracy class 0.4, real-time monitoring of pressure difference, triggering automatic backwash to achieve "cleaning immediately when clogged".

  • PLC Control Cabinet: Three control modes (pressure difference/timed/manual), automatic cleaning, fault alarm, data recording, no need for special personnel on duty.

Core Advantages · Efficient and Worry-Free

Continuous Operation: Backwash without shutdown, operating efficiency over 95%;

Intelligent Operation and Maintenance: Fully automatic control, reducing labor costs;

Economic and Energy-Saving: Renewable filter elements, greatly reducing consumable costs;

Clean and Safe: All-metal material, no secondary pollution.

Application Scenarios

Petrochemical, energy and power, fine chemical, water treatment, food and pharmaceutical, semiconductor, etc., suitable for various high-demand fluid purification needs.
