Energy-efficient ZS blower for wastewater treatment

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.

Energy costs can add up to 80% of the lifecycle cost of a blower. That's why we constantly develop new energy efficient models, consuming a minimum level of energy, such as the ZS VSD+. The Atlas Copco oilfree screwblower element is driven by our in-house developed liquid cooled permanent magnet motor. Combined with the Neos VSD inverter, this successfull energy-efficient variable speed driven solution runs trouble-free in the harshest environments. With the ZS VSD+ you don't need to worry about your process uptime and no hidden surprizes will occur when receiving the energy bill at the end of the month. 

Low pressure compressed air is the backbone of many production processes. The ZS is the latest addition to Atlas Copco’s air blowing solutions, manufactured to the highest standards of quality and reliability. Built to ensure complete product safety, ZS blowers guarantee a continuous, highly reliable, energy-efficient and 100% oil-free air supply for years on end.
