Floating Brush Aerators

Floating Brush Aerators are ideally suited for operation in municipal sewage treatment lagoons, especially shallow lagoon applications where vertical shaft-type aerators cannot operate.

在泻湖浮动刷曝气器中水平移动废水并产生圆形流动模式,以防止短路,并最大限度地提高泻湖处理能力。水平混合在整个泻湖中循环高氧化的水,从而产生氧气帽,以减少沉降污泥的厌氧分解的气味。

The effective mixing provided by Floating Brush Aerators is also useful to create mixed conditions to minimise algal growth, and to redistribute accumulated sludge more evenly over the entire floor/base of the lagoon, thus improving lagoon treatment capacity & performance.

Floating Brush Aerators are also suitable for aeration in oxidation ditches, Pasveer channels, SBRs, equalization basins and aerobic digesters of all sizes and configurations.
