Coarse bubble diffusers are mainly used thorough mixing capabilities. The rising air induces a strong current, thus removing sludge from the bottom of the tank. They are therefore a very good alternative for many mechanical aeration systems.

Coarse bubble diffusers produce 1/4 to 1/2 inch (6.4 to 13 mm) bubbles which rise rapidly from the floor of a wastewater treatment plant or sewage treatment plant tank. They are typically used in grit chambers, equalization basins, chlorine contact tanks, and aerobic digesters, and sometimes also in aeration tanks. Generally they are better at vertically "pumping" water than at mass transfer of oxygen. Coarse bubble diffusers typically provide half the mass transfer of oxygen as compared to fine bubble diffusers, given the same air volume.

Product Introduction

High oxygen Aerator Membrane Fine bubble Disc Diffuser features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency.
A highly effective check valve integrated enables the aeration zones to easily shut down operations (air -on /air - off) applications.

Salient Features- High oxygen exchange capacity with remarkable energy saving effect.- Power efficient with low energy consumption, saving about 30% of operating cost compared with general diffusers available in the market.
- Unique and uniform air distribution structure with tight bubble formation.- The open design of the aeration support reduces the impact of buoyancy on the aerator body thus increasing the diffuser life significantly.
