SURFACE MOUNTED AERATOR REPLACES SUBMERSIBLE SYSTEM

A tannery in Belgium has upgraded its wastewater treatment system with two venturi aerators “driven” by a single Gorman-Rupp pump. The exercise has been a great success, delivering improved performance and reduced maintenance.

The tannery had previously been running two 7kW submersible aerators and two 2.5kW submersible mixers, but the installation was problematic as poor mixing and low levels of transferred oxygen resulted in unacceptable levels of odour from the process. So the tannery management consulted the local Gorman-Rupp distributor, Hydro +, to review the application.

Two Venturi-Aeration VA-500 units were selected to deliver the correct amount of oxygen transfer for the application, and a single Gorman-Rupp T6A60S-B was selected to provide the flow and pressure to these “static” mixer/aerators. A venturi aerator was positioned at either end of the tank for the best mixing effect, and because the Gorman-Rupp pump is self-priming, it could be mounted beside the basin.

A venturi aerator draws atmospheric air into its mixing chamber when wastewater is passed through it at high velocity. This velocity breaks up biological matter as well as causing a venturi effect, introducing as much as 2.2-times the volume of air per volume of water.

And because all the equipment (the pump and the aeration units) is located outside the basin or lagoon, servicing is quicker, easier and safer for operators, reducing maintenance costs.

The new tannery installation has achieved much higher oxygen transfer, better mixing and a reduction in downtime. After the first 12 months of operation, the only maintenance required was an oil change.
