Key Applications
WWTP Biochemical Processing: Generates massive volumetric flow in anoxic and anaerobic tanks to keep suspended solids homogenized and prevent sludge settling
High-Density Sludge Agitation: With robust thrust capabilities and tolerance for fluid densities up to 9.6 lbs/gal (1150 kg/m³), it effortlessly handles heavy sludge mixing without motor overload
Energy-Optimized Aeration: Works in synergy with existing aeration systems to significantly reduce overall energy consumption while boosting the oxygen transfer rate during water circulation
Frequently Asked Questions
Is the mixer prone to clogging when processing wastewater with rags and long fibrous materials?
No. The QJB mixer features an optimized hydraulic swept-back impeller design. This specific blade geometry provides an exceptional self-cleaning function that naturally repels fibrous debris, actively preventing wrapping and clogging during continuous rotation.
How does the machine prevent water ingress and motor failure during continuous 24/7 submersion?
The mixer utilizes an independent oil chamber fortified with Double Mechanical Seals (Tungsten Carbide) and a uniquely sealed anti-wicking cable entry. Furthermore, it is equipped with a built-in moisture sensor and a thermal protection switch to ensure fail-safe, reliable operation.
