Economic Point

With the commissioning of the waste water treatment plant Nordkanal, which has been dimensioned for a design capacity of 80,000 population equivalents, new worldwide standards for the implementation of large membrane-activated sludge plants have been created both from a technical and from an economic point of view. The hitherto successful operation of this plant has already now contributed towards this technology becoming suitable for use in large waste water treatment plants. The now two years the waste water treatment plant Nordkanal has been in operation have once again demonstrated that even on a large scale, membrane-activated sludge plants are able to reliably produce purified effluent of excellent quality, while simultaneously providing a small-sized design. They prove advantageous everywhere small-sized designs are sought after and the purified effluent has to meet high or special requirements. Wherever purification requirements are intensified in the foreseeable future, whether with regard to the hygienisation of effluent, or in the framework of re-using purified waste water as industrial water or potable water or in order to protect natural drinking water resources from critical anthropogenic impacts, the membrane bioreactor process or membrane filtration is trend setting and will increasingly gain in importance.

Reduction Capacity

The capacity and efficiency of the existing activated sludge waste water treatment plant at SCA Graphic Laakirchen AG needs to be enhanced due to an expected future increase in waste water flow and COD-load. For the case of an existing upper limit of COD discharges into the river, the COD reduction rate of the waste water treatment has to be increased to a degree which is unobtainable by biodegradation only. Laboratory and pilot plant trials using a moving bed biofilm technique and an activated sludge treatment combined with ozone treatment and subsequent biofiltration have been performed with the aim to increase the COD reduction capacity and efficiency of the plant. The results show that the COD reduction capacity of the existing activated sludge plant can be increased by more than 100% by integrating a moving bed biofilm pre-treatment stage into the plant. In addition, improved sludge separation in the secondary clarifier was established. A special benefit of the ozonation plus biofilter treatment is a controllable COD reduction between 20 - 90% related to the outflow of the activated sludge plant. It is concluded that by integrating the investigated treatment techniques in the existing activated sludge plant the future increases in waste water flow and COD-Load can be handled satisfactorily without increasing bioreactor volume.
