Jet aspiration is a simple, efficient and cost effective solution to wastewater treatment and mixing problems. Liquid from the tank is pumped through a specially designed double nozzle assembly which aspirates air into the mixing section. The combined air/liquid plume is then discharged below the surface to provide high oxygen transfer and off-bottom solids suspension.
In the fixed units, the motive pump is submersible with an integrally mounted motor and is suitable for many different wastewater treatment and mixing applications. The jet aspirating nozzle assembly is mounted directly to the jet motive pump. The entire assembly is retrievable on guide rails for service and maintenance. The pump body is cast iron with a corrosion resistant coating. The jet aspirating nozzle assembly is fabricated out of stainless steel or corrosion resistant fiberglass.
Portable aspirators are submerged units which are effective bottom mixing devices. The nozzle is close to the basin floor providing scouring velocities which lift solids from the floor toward the surface. Multiple units can also be positioned to create a circular mixing pattern which will make more efficient use of mixing energy input. These units are adapted to holding tanks, aerobic lagoons, aerobic digesters with secondary solids, small oxidation channels, SBRs, ISAM™ and equalization basins. These can also be adapted to temporary aeration applications.
