The new £150m Arla Process and Packaging Facility in Aylesbury will process up to one billion litres of milk a year from British farms. Arla planned the new Dairy as a showcase of sustainable development, applying advanced process technologies and renewable energy solutions, targeting a zero carbon facility with zero waste to landfill.
To support this concept, Veolia installed a Memthane® wastewater treatment solution, with additional rainwater harvesting system. Memthane® is an Anaerobic Membrane Bio-Reactor (AnMBR) which maximises renewable energy production while producing superb quality effluent that can be reused or discharged directly to sewer. This leading-edge technology, developed by Veolia subsidiary Biothane, delivers a unique, small footprint solution that offers an array of benefits, reducing disposal costs while generating valuable biogas.
Despite the high concentration, and significant variation, of TCOD within the influent, the performance of the Memthane® system has proven to be robust; continuously producing treated effluent of exceptional quality.
Based on all 2014 data, the average TCOD removal is 99.4%. Additionally, the pore size of the UF membranes ensures a permeate that is effectively free from suspended solids.
