Automatic Backwash Filter

For more than 25 years, the AquaABF® Automatic Backwash Filter has received wide acclaim for its successful performance in municipal and industrial water and wastewater treatment. It has proven to be an efficient means of treating potable water, reducing turbidity and suspended solids in industrial process makeup water, and providing reuse quality effluent in municipal wastewater applications.


The AquaABF filter is a continuous rapid-rate, gravity filter utilizing granular media. The filter is simple to operate and offers a competitive cost and energy efficient design, making it the logical alternative to other filtration systems.
