QXB Series Floating Centrifugal Aerator (Pontosh Submersible Aerator)
Product Overview & Core Value Proposition
The QXB Series Floating Centrifugal Aerator (Pontoon Type) is a highly efficient biological treatment solution that combines 360-degree omnidirectional hydraulic circulation with direct air self-aspiration. Mounted on a durable, marine-grade floating pontoon system, this submersible centrifugal aerator floats independently on the water surface, making it completely independent of bottom topography or changing water volumes.
The QXB Advantage vs. QSB Series: While the QSB jet aerator focuses on directional, high-velocity linear thrust, the **QXB centrifugal design utilizes a specialized star-shaped impeller to fling water out horizontally in a full 360-degree circle**. This creates an expansive, circular horizontal convection zone that offers unmatched shallow-to-medium depth tank mixing and high oxygen transfer metrics.
Key Features & Industrial Advantages
360° Omnidirectional Aeration & Mixing: The centrifugal force creates a massive horizontal flow field in all directions simultaneously, maximizing the contact area between air bubbles and mixed liquor without creating any dead corners.
Perfect for Shallow & Massive Surface Water: Ideal for large, wide municipal and industrial stabilization ponds, landscape lagoons, and river restoration projects where linear jetting might cause shoreline erosion.
Zero Civil Infrastructure Investment: Eliminates the need for concrete base structures, underwater anchor bolts, or deep-pool mounting rails. The entire assembly floats and is held securely via simple mooring cables linked to the shore.
Uninterrupted Production Maintenance: No need to halt operations, drain aeration tanks, or rent expensive heavy machinery for installation or servicing. Maintenance is handled completely at the surface—simply guide the pontoon back to the shoreline.
Tailored International Configurations: Built from robust materials including Cast Iron, SUS304, or SUS316L for chemical resistance. Fully customizable power setups (e.g., 380V, 400V, 415V, 440V at 50Hz/60Hz) to perfectly align with specific regional grids.
Target Industrial Applications
Municipal & Industrial Aerated Lagoons: Efficiently maintains dissolved oxygen levels across wide, shallow surface water areas without creating specialized flow paths.
Landscape Lakes, Ponds & River Ecosystems: Rapidly injects oxygen into stagnant waters to reverse eutrophication, eliminating foul odors and preventing algae blooms without disturbing soft bottom silt layers.
Industrial EQ & Buffering Pools: Continuously handles variable organic loading and dramatic fluid elevation shifts common in chemical and food-processing shifts.
