Three Water Companies have adopted advanced Moving Bed Biofilm Reactor (MBBR) technology from Veolia Water Solutions & Technologies in the UK.
London/United Kingdom – The Moving Bed Biofilm Reactor (MBBR) was developed by Veolia subsidiary Anox Kaldnes in the late 1980’s and is now used around the world for both Municipal and Industrial applications. Based on fixed film technology, the key to the process is the scientifically designed suspended carrier media, Veolia explains. Recently, the company has introduced the new Anox-K5 carrier media. With a protected specific surface area of 800 m2/m3, the shape and dimensions of this product offer significant benefits for both new and upgraded wastewater treatment plants.
Treating both Municipal and Industrial Waste Water
At Anglian Water’s Corby Wastewater Treatment, the circular concrete MBBR unit will be used to increase the capacity of the plant that treats a combination of domestic wastewater and industrial effluent. The MBBR process provides the ability to cope with fluctuating industrial loads, whilst producing a consistently high quality final effluent.
A new MBBR is also being installed by Yorkshire Water at Cudworth near Barnsley for tertiary nitrification. Here the media will be in a multi-celled rectangular concrete unit and will be followed by Veolia’s Hydrotech Discfilters to ensure that the tight BOD discharge consent is achieved.
High Purity Effluent Combined with Reduced Footprint
As part of Dŵr Cymru’s multi-million upgrade at Swansea Bay STWs - MBBR technology from Veolia Water Solutions & Technologies has been selected as the optimum solution where additional capacity is needed to accommodate a rising population, whilst meeting tighter discharge consent to protect the waters of Swansea Bay. Converting the existing AS plant to MBBR technology utilising the new Anox-K5 media was the ‘best value’ solution due to the limited space available for the required capacity increase. The Veolia solution enables the capacity of the plant to be increased and provides an improved effluent discharge quality without the need for additional civil structures on a site with limited space. Veolia worked closely with Imtech and Dŵr Cymru personnel to develop the MBBR solution.
