There are a variety of technical means for aerating lagoons with most providing costly treatment due to the need for electricity. Most treatment technology provides effective surface aerobic treatment but fail to address the anaerobic conditions near the centre and bottom of the lagoon.
Demands on sewage lagoon operators are increasing daily. With increases in local population, changing legislation, deterioration of aging systems, and unusual weather are all factors affecting sewage lagoon performance.
Windmill Aeration Systems are a long accepted method of adding oxygen into standing water facilities. Traditional users are farmers who need clean aerated water for livestock watering and crop irrigation. Commercial fish farmers also use aeration windmills to provide them with aerated water in an economical way.
“Improving Sewage Lagoon Performance Using Windmill Aeration” Newer users include rural municipalities who use aeration windmills to oxygenate their sewage lagoons thereby accelerating the degradation process. As energy costs continue to rise and environmental issues become more critical in the decision making process, the windmill aeration system becomes an increasingly more attractive proposition. The typical facultative sewage lagoon operator uses a system of primary and secondary cells. Adequate oxygenation is an essential part of the degradation process. As more people are attracted back to the country by the cottage/acreage lifestyle this places an additional burden on the rural sewage lagoon. New lagoon installations are extremely expensive and communities are very receptive to any method which makes their lagoons more efficient.
