GSJ/QSJ Series Hyperboloid Mixer for Wastewater Treatment
The GSJ/QSJ Series Hyperboloid Mixer represents advanced agitation technology specifically engineered for deep-tank mixing applications in environmental engineering and municipal Wastewater Treatment Plants (WWTPs). Featuring a uniquely designed hyperboloid streamlined impeller, this system generates a massive, low-shear, umbrella-shaped circulating flow that originates from the tank bottom, ensuring complete homogenization of suspended solids while actively preventing sludge settling.

Key Applications
Massive Biochemical Tank Homogenization: Ideal for coagulation tanks, anoxic tanks, and anaerobic tanks in municipal WWTPs. The bottom-mounted hyperboloid impeller creates powerful bottom-up radial thrust that maintains biological floc in suspension.
Low-Shear Process Mixing: In denitrification and phosphorus removal processes, the gentle umbrella-shaped circulation ensures high-efficiency solid-liquid-gas mixing without damaging the delicate structure of activated sludge flocs.
Frequently Asked Questions
What is the defining advantage of a Hyperboloid Impeller over traditional submersible propeller blades?
While traditional propellers often create localized jets, the hyperboloid impeller's unique fluid dynamic geometry forms a continuous, dead-zone-free circulation across the entire tank floor. It provides significantly wider flow coverage area at lower rotational speeds, substantially reducing energy consumption when processing the same volume of fluid.
How should I choose between the GSJ and QSJ models for my specific tank environment?
The GSJ is a dry-installed mixer where the motor and gearbox are mounted on a bridge above the waterline, offering easy daily maintenance without touching the wastewater—ideal for tanks with existing top bridges. The QSJ is fully submersible, operating underwater with minimal noise and zero visual obstruction, making it perfect for deep tanks without bridges or facilities with strict noise control regulations.
