Coarse Bubble Diffusers

Coarse bubble diffusers are generally used for pollution control technology, they are used to aerate or mix waste-water meant for sewage treatment plant. They produce 1/4 to 1/2 inch bubbles which go up rapidly from the floor of a wastewater treatment plant or sewage treatment plant tank. They are normally used in grit chambers, chlorine contact tanks, equalization basins, and aerobic digesters, sometimes also in aeration tanks. Usually, they are superior at vertically “pumping” water than at mass transport of oxygen.

Application: Areas where non-newtonian or pseudoplastic fluids are present, such as a digester with very high solids concentrations, it is suggested to use coarse these over fine bubble diffuser, due to the bigger bubbles formation ability to shear all the way through more viscous waste-water.

Advantages

1. Moderate efficiency.
2. High capacity Wide Band bubble diffuser.
3. Highly recommended at high solid concentrations.
