Product Description
Detailed Specifications & Features
PUR Self-Cleaning Impeller | 100,000-Hour Bearing Life | Submersible Flow Booster | WWTP Denitrification Tanks
Product Overview
The QJB Submersible Flow Booster is a low-speed flow maker specifically engineered for aeration tanks in municipal and industrial Wastewater Treatment Plants (WWTPs). It features lightweight, high-strength "banana" shaped swept-back blades made of Polyurethane (PUR) or Fiberglass Reinforced Plastic (FRP). Driven by a low-speed motor, it generates a massive, gentle volumetric flow with a wide coverage area. Protected by an IP68 enclosure and maintenance-free bearings with a design lifespan exceeding 100,000 hours, it perfectly combines reliable fluid propulsion and mixing functions with minimal energy consumption.

Key Applications
- WWTP Biological Processes: Provides vital circulation flow for aeration tanks, making it ideal for nitrification, denitrification, and phosphorus removal processes in municipal and industrial facilities.
- Massive Bulk Flow Creation: Utilizing massive impeller diameters ranging from 43.3 to 98.4 inches, it generates a strong, low-shear bulk flow in large rectangular or racetrack tanks, maintaining suspended solids and preventing sludge sedimentation.
Frequently Asked Questions
What are the primary advantages of using PUR or FRP for the impeller blades?
Polyurethane (PUR) and Fiberglass (FRP) provide a lightweight yet high-strength structure with superior corrosion resistance. Combined with the "banana" shaped swept-back geometry, these blades offer an exceptional self-cleaning function that actively prevents rags and fibrous debris from wrapping and clogging.
How does this flow booster achieve its high energy efficiency?
The system operates on a highly efficient triad: low motor power, low rotational speed, and a large impeller diameter. This combination creates a massive volumetric flow with minimal energy input. When synergized with aeration systems, it significantly reduces the overall energy consumption of the plant.
