How Does an Backwash Filter Work

JX Filtration March 10, 2025 Backwash Filter

An automatic backwash filter is a precision filtration device that directly intercepts impurities in water using a mesh screen and sand.

It removes suspended solids and particles, reduces turbidity, purifies water, and prevents scaling, algae growth, and corrosion. This ensures better water quality and protects other system components.

The filter operates automatically based on pressure differentials or a preset timer, performing backwashing to discharge accumulated impurities.

Cost-Saving and Efficiency Benefits:
By implementing a backwash filter, irrigation system performance can be significantly improved, extending the lifespan of water-saving irrigation systems. When integrated with fertigation technology, crop yields can be substantially increased while achieving notable savings in water, fertilizers, and labor.

Market Applications:
Backwash filters are widely used for treating river water, reservoir water, pond water, and lake water. They are particularly effective for water sources with organic content exceeding 10 mg/L, making them ideal for various irrigation systems such as drip irrigation, sprinkler irrigation, and micro-sprinkler irrigation.
