Diffusers
Enviroquip offers diffusers for use in coarse and medium bubble aeration in water and wastewater treatment applications. Its MS coarse bubble diffuser and TransMAX medium bubble diffusers are drop type diffusers that can be used alone or in conjunction with shear or draft tubes. Separating the air-metering orifice from the diffuser and locating the orifice above the liquid level in the basin eliminates clogging.

Aeration system
EIMCO(r) has introduced a patented Dual Impeller Aerator for use with the company's Carrousel(r) oxidation basin system. Combined with the benefits of the Carrousel's surface aerator, the dual impeller aerator incorporates a specialized "lower turbine" which is attached to the same shaft. Locating the lower turbine near the floor of the basin directs mixing energy along the floor, thus augmenting channel velocities provided by the surface impeller.
