Product Overview

CM Aquatechnik supplies submersible propeller and hyperboloid mixers for anoxic and anaerobic zone mixing in biological treatment tanks, equalisation basins, and sludge holding tanks. Properly designed mixing ensures uniform substrate distribution, prevents sludge settling, and maintains suspended solids in suspension without introducing oxygen in anoxic zones.

Key Features

Low-speed propellers (40–140 rpm) prevent sludge flotation in anoxic zones
Guide rail mounting enables easy raising and lowering without dewatering
Double mechanical seal with oil chamber prevents wastewater ingress
IE3 motor efficiency class reduces running costs by 10–15%
Hyperboloid design creates optimal 3D flow pattern in circular tanks
ATEX Zone 1 certified versions available for biogas-covered digesters

Applications

Anoxic zone mixing in biological treatment Equalisation tank mixing Sludge storage and holding tank agitation Anaerobic digester mixing Chemical dosing tank mixing Stormwater detention basin mixing
