Polishing refers to the treatment needed to prepare process water of the required specifications for discharge or reuse. Even wastewater can be reused after effluent polishing with ultrafiltration. If industrial reuse requires reverse osmosis, the effluent needs to be free of suspended solids and turbidity.
Ultrafiltration (UF) permeate is safe for reuse applications and could also be discharged into water bodies used for recreational purposes. It will have a turbidity of less than 0.1 NTU and be free of any bacteria, viruses and chlorine-resistant microorganisms. Combined with a silt density index (SDI) of less than 3 at all times, UF permeate also meets all protection requirements of RO membranes. Pentair’s membrane technology applications have a footprint that is considerably smaller than traditional media filters.
All of our UF applications benefit from a simple process setup (also inline with RO), easy cleaning and maintenance, consistently high effluent quality, and low OPEX.
