Membrane Filtration Brochure - .PDF file.

Axium Process has designed, built and commissioned a filtration plant, including the pre-filters and membrane systems, for Axminster Carpets’ wool processing factory at Buckfast.

The carpet manufacturer has installed a large water-recycling plant (WRP) that is believed to be the UK’s first WRP that has a closed-loop system with target ‘zero discharge’ to sewer.

The filtration plant, built by Axium Process, has a total membrane area of 3,000m2, including both tubular ultra-filtration and spiral-wound reverse osmosis membranes.

The complete WRP was supplied by Puriti and is designed to recycle all of the company’s wastewater.

Only a small quantity of slurry leaves site for further processing by anaerobic digester, the final products being compost and electricity.

The water recovered is pure, free of mineral salts and natural organic matter and is ideal for dyeing.

Having to deal with variability of the supply from the River Dart is eliminated.

The water recycling process includes staged filtration followed by staged evaporation of concentrates.

The company is expected to save a substantial amount of money with zero discharge to sewer.

In addition, the use of chemicals has been reduced and a significant amount of energy saved by returning hot water for process applications.

The WRP is processing up to 400m3 of factory effluent per day – the total wastewater volume from Axminster’s wool scouring and dye house operations.
