A District created to promote public health decided to scrub off-gas odours from its Vallejo wastewater treatment plant. The two open aeration basins were targeted as part of the odour control upgrade. A retractable geomembrane cover was selected for the basins, which combines a gas-tight barrier with low life cost benefits.

The next in Ken Sutherland's series of articles, on the smaller end-use equipment application sectors, features the use of filtration equipment in the manufacture of machinery, including the production of transport equipment as well as equipment usage in the operation of transport systems. The sector is not actually small in volume terms, but is considered in this series of articles because of its use of only a relatively narrow range of equipment types.
