Filtration

Wastewater treatment plant

At the end of treatment in a wastewater plant, water has to respect quality standards, be it a realease in natural environment or a re-use (industrial water). Filtration enables to absorb a temporary increase in suspended solids in this water.

For treatment before re-use, filters are usually between 100 and 200 microns. With a Hectron filter, maintenance is reduced to a minimum.

Before UV, a finer filtration (20 µm) is usually chosen to protect the lamps and guarantee their efficiency

Suitable equipment

AG AUTOMATIC FILTERS

The AG range filters equip several dozen wastewater treatment plants in France. The suction ramp washing system is very efficient and suitable for the clogging materials present in the wastewater treatment plants.

Benefits

  • Fully automatic
