Tsurumi's submersible aerators are used at wastewater treatment facilities to aerate and agitate industrial wastewater, livestock wastewater and other water that needs treating. More specifically, they provide the primary aeration in reactor tanks and aeration tanks at the heart of the water treatment process, and aeration and agitation in flow regulating tanks. These aerators produce tiny bubbles in the wastewater by furiously mixing in air they draw from above the wastewater's surface, and discharge the aerated wastewater to the outside. The mixed flow of air and water contains a high amount of dissolved oxygen and makes aeration and agitation very efficient.

Tsurumi offers two kinds of aerators in three series. The TRN-series features Tsurumi's baseline submersible aerators that produce a high amount of dissolved oxygen and enable efficient aeration and agitation, while the BER-series and the PLS-series with aeration kit are submersible jet aerators that generate a powerful unidirectional flow. All three series are built to draw air themselves while submerged in wastewater, so they can aerate and agitate wastewater without requiring a blower, which greatly reduces both installation space and noise.

Despite their simple structures, Tsurumi submersible aerators are packed with original technologies that have been tested and proven over many years of R&D and market use, such as an anti-wicking cable, dual inside mechanical seals with silicon carbide faces and Oil Lifter. Moreover, they are designed and built for the degree of reliability and durability required for 24 hour-a-day continuous operation. Plus, when it is time for maintenance, it suffices to raise just the pump from the tank; the tank does not need to be drained as is the case of a plate/tube diffuser, so these aerators are economically beneficial in terms of running costs.

Tsurumi’s TAR-series submersible air mixers combine aeration and mixing to promote wastewater treatment at public and industrial treatment plants. The powerful current discharged from the high-performance axial-flow impeller shears the air supplied by the blower into tiny bubbles, forming a furious flow of mixed air and water that efficiently delivers oxygen throughout the wastewater. Moreover, Tsurumi’s original downward 4-directional discharge design spreads that mixed flow outward along the bottom of the tank toward the edges to ensure homogeneity.
When paired with a Tsurumi rotary air blower, the TAR air mixers not only offer effective aerobic agitation but they can also be used for both aerobic and anaerobic processing by simply switching the blower on and off.

Like Tsurumi’s core product lines of submersible pumps, the TAR air mixers come loaded with numerous original technologies tested and proven over the years, including anti-wicking cable, motor protector, leakage sensor, dual inside mechanical seals with silicon carbide faces and Oil Lifter. These superior features underscore the high reliability, lasting durability and sound quality that enable continuous duty.

As an added convenience, the TAR-series can be installed on a guide rail fitting device that allows the air mixers to be easily lowered and raised into and out of tanks on guide rails. This has huge economic advantages compared to air diffusion systems that are typically anchored to the tank bed, as the tanks do not need to be drained when mixers require maintenance, which can greatly reduce downtime.
