Scottish Water Lowers Costs 25%

Applied CleanTech Announces that a Pilot Project to Test its New Recycling Technology for Waste Water was Completed at Dunbar and Aviemore Waste Water Treatment Works with Promising Results

Scottish Water has been testing whether value can be recovered from sewage while reducing maintenance and power costs.

George Ponton , Head of Innovation at Scottish Water , said: "This new technology is a very fine filter that captures all the cellulose and some of the fats, oils and grease coming into the waste water treatment works. The solids are then pasteurised producing a pellet material called Recyllose™.

"These pellets could then be used as a raw material in paper, plastic, construction, energy and other industries.

"This can substantially reduce the amount of sewage sludge produced: we can run the plant using less power, reduce sludge tankering frequency and cut down maintenance requirements.

"It also reduces our carbon footprint and emissions by using less power and resources, and increases the lifespan of the equipment we use. Overall the addition of the process could reduce operating costs between 20-30%, and we can pass any potential savings on to our customers.

"By creating less sludge, we also don't have to send as much of it to be processed at our sludge treatment centre in Edinburgh. Sludge is a by-product of the waste water treatment process, and is treated under extremely strict regulations. In many cases the end product is a recyclable soil nutrient."
