Dairy Crest invests in wastewater treatment and water reuse plant
Aquabio has been contracted to equip Dairy Crest's Severnside Dairy in Gloucester with a wastewater treatment and water reuse plant as part of a £3.5M deal. The plant will take 15 months to complete, and will treat wastewater discharged to the local watercourse and additional treatment to ultra-pure quality for reuse.
It will comprise Aquabio's AMBR LE Industrial Membrane Bioreactor (MBR) and is one of the largest applications of its kind in the UK. MBR is a combination of a membrane based filtration process (ultrafiltration) with an aerobic or anaerobic biological reactor. AMBR LE with Reverse Osmosis (RO) processes produce effluent of a high enough quality to be re-used in industrial application, or discharged to stringent watercourse requirements.
The advantages of MBR filtration over conventional processes include a small footprint and easy retrofitting and upgrading of existing wastewater treatment plants.
Around 60% of wastewater at the plant will be treated to potable standards for reuse. The plant will have the capacity to recycle 550Ml of water a year.
The plant will bring many benefits to Dairy Crest, including a cost reduction for water supply and effluent discharge, security and sustainability of the water supply, and a reduced water footprint.
Matt Bardell, Dairy Crest’s group sustainability manager, said: “This investment will deliver a step-change in water abstracted at Severnside. It builds on our previous group wide successes in water efficiency and makes a significant contribution to our longer term corporate commitments.”
