Warden Biomedia’s moving bed biofilm reactor (MBBR) media, which is being designed to give enhanced nutrient removal to meet the challenges of AMP7, is currently being tested at Cranfield University’s National Research Facility for Water and Wastewater Treatment. The MBBR process, which uses specially designed buoyant media to support a variety of microbial colonies in a biofilm, is increasingly being used in municipal and industrial wastewater treatment as it provides robust, small footprint plants and can be easily retrofitted to upgrade existing plants or in greenfield sites.
Warden Biomedia’s media has been developed in conjunction with Cranfield University through a three-year £300,000 Innovate UK Knowledge Transfer Partnership. Now, a year into the partnership, the media is moving from bench to pilot scale trials. KTP Associate Anjani Parsotamo says “The new product developed by Warden Biomedia and Cranfield University will give much more efficient removal of nitrogen and phosphorous from wastewater compared with conventional biological processes, a major challenge facing the water industry in AMP7. It will improve cost-effectiveness and sustainability and pave the way for the next generation of wastewater treatment solutions.”
Warden Biomedia has been manufacturing media for attached film processes like trickling filters, SAF and MBBR processes for many years, and are experts in manufacturing the complex shapes needed from polyethylene and polypropylene, virgin or recycled plastics. These plastics are perfect for MBBR media because they possess similar densities to that of water, allowing sufficient buoyancy and enabling good mixing. "Our aim is to satisfy present and future market demands by anticipating them at an early stage”, says Junaid Hassan, Sales & Marketing Manager at Warden, “and this new development will put the UK at the forefront of biological process technology.”
