Tsurumi TRN submerged aerator wastewater pumps

Tsurumi’s TRN submerged aerators mix the tank and add large quantities of oxygen. They do not require membrane jets, which means they cannot become blocked. This allows breweries, producers of mineral water and dairies to satisfy the discharge limits.

The oxygen bubbles required for the biological preclarification phase are generated by means of rotation. Almost as a side effect, the content of the tank is kept in motion to prevent sediments forming. The fans do not require a compressor, nor do they need to be attached to the structure because they are simply lowered onto the base of the tank. Only a power cable, suction line and retaining chain are required. The shape of the tank is also irrelevant.

If several fans are used, the clarification process runs without interruption should one unit need to be removed. There are 10 models with motor outputs ranging from 0.75 to 40 kW in the product range. The aerator adds up to 600 m³ air/h. It is suitable for expanding capacity levels or as a backup for existing systems. It is also possible to use the unit together with aerators from other manufacturers.
