Challenge
The ACSD South Plant is a conventional activated sludge plant with an average low of 19.5 MGD, and a maximum flow of 45 MGD. Constructed in 1974, it receives domestic and commercial wastewater from Albany, and has no industrial wastewater component. ACSD required a state-of-the-art disinfection system that could quickly and efficiently respond to the rapid flow increases during storm events, and then could just as efficiently scale back as the flows subsided.
Solution
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. UV systems are safe and effective,eliminating 99.99% of pathogens – including bacteria, viruses and parasites. Considered a more environmentally friendly, UV achieves disinfection goals without creating chlorine byproducts or adding harmful chemicals to the water – a definite plus when discharging into recreational waters.
