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. To permit energy optimisation and to substantially reduce energy bills in these continuously operating plants, Atlas Copco's innovative air blowers incorporate the latest energy efficient design and technologies.
