Industrial Wastewater Applications: Municipal Waste

Waste Water

Various types of wastewater can be treated aerobically using MBR Technology.

The Wehrle MBR-HS process is suitable for the treatment of highly loaded wastewater. This includes wastewater from the printing, chemical, and pharmaceutical industries, as well as wastewater from waste oil and special waste disposal, and road tanker cleaning.

The Wehrle MBR-MS process is suitable for the treatment of medium strength wastewaters, such as wastewater from breweries, dairies, chemical and galvanising plants, and the automotive industries.

Municipal wastewater with low loadings is typically processed using the Wehrle MBR-LS system. The process can also be used for the treatment of other weak wastewaters such as black and grey wastewater from ships, wastewater from laundries, the catering trades and hotels.

The Wehrle MBR-DD process is used in wastewater treatment situations where there is direct discharge of effluent, with associated strict consents.

Low Energy Crossflow operation on larger MBR systems can reduce significantly the operating cost of Wehrle process solutions.

Anaerobic

Wastewater with very high loadings can be treated anaerobically using our Anaerobic Fermentation Technology.

The fermentation of wastewater has gained increasing importance over the past few years. On the one hand higher organic loads can be treated, technically and economically, by anaerobic treatment. On the other, it is possible to recover energy with the biogas produced by the fermentation process; a real benefit both economically and environmentally. For these reasons, anaerobic wastewater treatment is installed in many industries, such as in the paper, milk and breweries.

The combination of anaerobic and aerobic wastewater treatment has been successfully implemented by Wehrle for many years. Our SBR and MBR technology work extremely well in a tertiary treatment capacity following our Anaerobic Fermentation Technology.
