Duraflow has developed the best microfiltration filter for pre-treatment of industrial wastewater for compliant discharge or for excellent pretreatment to Reverse Osmosis water recycling. Duraflow membranes can filter wastewater with solids concentrations u to 2% solids while producing crystal clear filtrate with no suspended solids and SDI below 2. The membrane is durable enough to be cleaned regularly with bleach, mineral acids or peroxide. This makes our membranes excellent protection for downstream Reverse Osmosis membranes.
