Customizability Water Treatment System - Back Flush Valve
1 . Descriptions:
Backwash valves wastewater treatment systems and pure water treatment systems.In wastewater treatment systems, they ensure the effective removal of contaminants, maintaining optimal filter performance. In pure water treatment systems, they help sustain the quality of filtration, ensuring consistent production of high-purity water. A backwash valve is specifically designed to clean a filter or filtration system by reversing the flow of water, flushing out impurities and deposits from the filter media to restore its filtration capacity. The working principle involves changing the direction of water flow: as water enters the filter through the inlet, the filter media retains impurities while allowing purified water to flow out through the outlet.
When preset backwash conditions are met, such as a specific timing or pressure difference, the backwash valve switches to backwash mode. Reverse flow enters the filter through the backwash port, and a strong water flow scours the filter media, removing impurities. The flushed impurities are then discharged through the discharge port, effectively cleaning and regenerating the filter medium. After backwashing, the valve switches back to normal filtration mode, allowing the system to resume regular operation.

3 . Main Performance Parameters:
1. Automatic backwashing: with automatic control function, it can be backwashed automatically at regular intervals or according to the pressure difference.
2. Efficient cleaning: strong reverse water flow effectively removes the impurities in the filter media and restores the filtering effect.
3. Water-saving and energy-saving: the backwashing process uses less water, which saves water resources and reduces operational energy consumption.
4. Corrosion resistance: the valve body and internal components are made of corrosion-resistant materials, suitable for a variety of water environments.
5. Convenient maintenance: reasonable structural design, easy to disassemble and install, easy for daily maintenance and overhaul.
4 . Appliance:
1. Water treatment system: used for filter backwashing in water treatment plant, sewage treatment plant, industrial wastewater treatment and other systems.
2. Industrial circulating water system: Used for cooling water filtration and backwashing in industrial circulating water systems such as power plants, chemical plants, iron and steel mills.
3. Agricultural irrigation: used for drip irrigation and sprinkler irrigation filter backwashing in agricultural irrigation systems to ensure irrigation water quality.
4. Swimming pools and water features: used in swimming pools, fountains and water features to backwash the filtration system and keep the water quality clean.
5. Other applications: widely used in water filtration systems in paper making, pharmaceutical, food and beverage industries.
