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.

Screw Versus Lobe Technology Screw Versus Lobe Technology

The aeration blower system accounts for up to 70 % of the energy usage in a typical biological wastewater treatment plant. Thanks to, Atlas Copco's innovative oil-free screw blowers, you can save about 30% more energy compared to conventional lobe technology: a significant cost reduction!
