Antiscalant developed for Wastewater RO

Antiscalant developed for Wastewater RO – Following two years of R&D and three years of pilot testing, American Water Chemicals (AWC) has completed its first full-scale delivery of a new RO antiscalant product to the Orange County Water District (OCWD) for its Groundwater Replenishment System (GWRS). The iconic 70 MGD (264,950 m3/d) GWRS—which employs MF, RO and UV/H2O2 to treat secondary effluent—had experienced numerous silica-scaling incidents, which had forced them to resort to the use of ammonium bifluoride as an RO membrane cleaner.
