Water Cooled Blowers provided by us, are commonly employed in activated sludge facilities to provide aeration and facilitate aerobic digestion. Solids are kept suspended in channels and aerated grit chambers, which is critical for a healthy treatment ecology. Blowers are extremely effective. For a given volume of air, the cost of operating a blower is a fraction of the cost of using compressed air. It also produce clean air because they do not utilize oil as a lubricant, therefore there is no risk of oil droplets or residue in the air stream.
