An old sewage treatment plant needed support for the process of oxidation/oxygen input.
The oxidation ditch of an old sewage treatment plant needed more oxygen input to increase capacity.
After visiting the plant Verbis Kft. and the experts of Tsurumi Europe GmbH. advised to install 6 pcs of Tsurumi 32TRN21.5 submersible aerators placed on a special KPE plate, which helps to guide the flow towards the main flow of the ditch.
After a few weeks of operation the measured values of the purified sewage reached the required limits. The system operates clog-free and quietly, power consumption and the needed maintenance is minimised compared to the outdated old devices.
In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
