After mechanical treatment, about 60 – 70% of the contaminants are still dissolved in the sewage. Microbiological methods are used to degrade this sewage with organic contaminants. Wilo low-speed submersible mixers are used to implement the biological treatment process for suspending contaminants and generating flows in the activated sludge tank. With their two-stage planetary gears, 2- or 3-blade propellers and stands that can be positioned freely in the basin, they can be custom-configured for any requirements. For a deposit-free treatment process.
To prevent solid material settling in the basin on drainage, it must be whirled up from the base and diffused. The high-speed Wilo submersible mixers have proven themselves in these applications. The direct-drive mixers are so compact that they are easy to install and submerge, even in the tightest spaces. Retrofitting in existing constructions is also easy. For special applications in pump chambers, Wilo submersible mixers can be installed on the discharge pipeline or tank ceiling via a flexible pipe bracket.
