UV disinfection: wastewater treatment plants in West Virginia
18 plants · 8% of the state · 9 MGD reported by 16 plants
Klarifi identifies 18 publicly owned wastewater treatment plants with uv disinfection in West Virginia, 8% of the 232 plants in the state (9 MGD reported by 16 plants). The largest is City Of Wheeling - Water Pollution Control Division in Wheeling at 4.8 MGD.
Ultraviolet disinfection destroys pathogens in the final effluent without chemicals or a chlorine residual. It has replaced chlorine at many plants since the 2000s and needs lamp, ballast and sleeve replacement on a fixed cycle, which keeps these plants in the market for UV suppliers.
