Aeration is typically the largest cost for activated sludge treatment plant operation and is a common target for efficiency initiatives.
The most common aeration technology consists of blowers powered by electric motors. Now APG-Neuros, a manufacturer of high speed turbo blowers, has developed an alternative that uses biogas to fuel a gas turbine that directly drives the impeller feeding air to the secondary treatment basins.The biogas fuel source essentially eliminates the cost of utility electricity for aeration. The complete aeration package has a favorable economic payback when compared with electric blowers, according to the manufacturer.In many cases, the technology makes use
