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. The Atlas Copco ZS+ blowers come in a fully integrated package, including Variable Speed Drive (VSD) to precisely match the air delivery to the customer's air demand, reducing the energy bill of these continuously operating plant significantly.
