How It Works. The AquaABF is designed to filter water and backwash cells simultaneously during normal operation. By design, the filter bed is divided horizontally into 8 in. or 12 in. (20.3 or 30.5 cm) wide cells. Inlet water floods the sand bed through multiple inlet ports via gravity and flows through the granular media and porous plate.

Backwashing is a form of preventive maintenance so that the filter media can be reused. In water treatment plants, backwashing can be an automated process that is run by local programmable logic controllers (PLCs).
