    Safe, Energy Efficient Disinfection For 45 MGD Combined Sewer WWTP Improves Water Quality

    The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.

Municipal Wastewater Treatment Plants Benefits From Energy-Efficient ZS Screw Blower Municipal Wastewater Treatment Plants Benefits From Energy-Efficient ZS Screw Blower

In conventional wastewater activated sludge plants, millions of bacteria feed on organic waste, breaking it up into carbon dioxide, nitrogen gas and water. Because the bacteria need oxygen, large amounts of air are blown in the aeration tanks. The aeration blower system accounts for up to 70 percent of the energy usage in a typical biological wastewater treatment plant.
