Coarse Bubble Diffusers

Coarse bubble diffusers are commonly used for pollution control technology, they are used to separate or mix waste water product for sewage treatment plant. They produce 1/4 to 1/2 inch bubbles which rise rapidly from the floor of a waste-water 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.
Application : Areas where non-Newtonian/pseudo-plastic fluids are present, such as a digester with very high solids concentrations, it is recommended to use coarse bubble waste water diffuser over fine bubble waste water diffuser, due to the larger bubbles creation ability to shear through more viscous waste water product.
