Filtration in wastewater treatment
At the end of treatment in a wastewater plant, the water has to respect quality standards, be it a realease in natural environment or a re-use. Treatment plants are never immune to a temporary increase in suspended matter in this water, with the risk of exceeding legal limits.
The installation of a filter secures these discharges. The choice of an automatic filter enable to avoid the constraint of replacing the cartridges. A 100 or 200 microns filtration degree is usually enough.
AG AUTOMATIC FILTERS
AG series filters are the most used for this application ; they equipp dozens of wastewater treatment plants in France.
AS AUTOMATIC FILTERS
AS filters are also suitable , when the filtered water outlet is on a low-pressure network, or at open air.
