The Hydro-Ceal coarse bubble air diffuser is a result of years of extensive research and development to produce a coarse bubble diffuser with excellent oxygen transfer and mixing due to its double air shear design. Unlike other coarse bubble diffusers on the market, diaphragms are molded directly onto the diffuser disk body and will not blow off.
Air is sheared as it discharges out of the air orifice of the diffuser body and again as it crosses over the diaphragm baffles. If it is not sheared at this point, it will shear along the diaphragm edge to product a combination of large (10-20 mm diameter in clean water) and small bubbles (2-4 mm) for excellent mixing and oxygen transfer. When airflow stops, the diaphragm instantly seats against the diffuser body by the pressure of the liquid, preventing backflow and clogging.
Hydro-Ceal diffusers measure 3-1/2" in diameter. Kraton polymer elastomer membranes and heat stabilized, glass-filled nylon bodies provide excellent chemical resistance and strength. HydroCeal diffusers are ideal for various applications including aeration chambers, aerobic digesters, aerated channels, post-aeration chambers and dechlorination systems.
