    Easing the cost of phosphorous removal in AMP7 How will you ensure accurate dosing of chemicals? by Bruce Quilter, Sector Specialist - Industrial & Environmental, WMFTG

    Treatment chemicals are the largest cost to water companies. Chemical use lies at the forefront of cost-saving plans as the water industry in England and Wales enters the new regulatory asset management period (AMP7). They also carry a heavy embedded carbon footprint due to the scale of production and transportation they represent.

    Environment Times is raising money for the homeless by creating a 'virtual ecohouse'. Milestone Design is one of the donors. They write: "Our first faltering steps into eco design began in 2006 when our directors, Julian and Jan Richards, were sat at home treating themselves to the odd gin & tonic or two(ish). At some point of the evening one of them said, "Go on then ... we've been recycling for ages and I've never seen a thing in the shops that's made from the things we recycle.... what CAN we actually buy that's recycled?"

Supermarkets can use Formula One technology for energy saving fridges

A new aerodynamic device that reduces the energy consumed by commercial refrigerators uses technology deployed in Formula One racing cars.

Williams f1 fridges1Williams Advanced Engineering, the division of Williams that commercialises Formula One derived technology and knowhow, has collaborated with UK start-up Aerofoil Energy to develop a new aerodynamic device that can give a turbo boost to reduce the energy consumed by refrigerators in supermarkets and convenience stores.

Energy consumption makes up a significant percentage of a supermarket's operational costs, with energy hungry refrigerators that keep the produce cool the largest consumer of power.

Open fronted multi deck refrigerators that line the aisles of supermarkets consume excessive energy, with some of the cold air used to cool produce spilling out into the aisles resulting in increased energy consumption and "cold aisle syndrome" which can be unpleasant for shoppers.

Aerofoils are carefully designed and engineered profiles that control the direction of air flow. Aerofoil Energy and Williams are developing a new retrofittable aerofoil system that attaches onto each refrigerator shelf to keep more of the cool air inside the refrigerator cabinet.

This innovative technology will result in significant energy savings for supermarkets and convenience stores, with corresponding benefits for their carbon footprint. The technology will also make the shopping experience more pleasant for consumers.

Williams f1 fridges2Aerofoil Energy are working closely with Williams to refine the aerofoil concept, utilising Williams' proven expertise in aerodynamic design and testing from four decades of success in Formula One racing. Williams' Advanced Engineering division is using computational fluid dynamics to model and simulate new designs before testing them at the Williams factory in Oxfordshire.

A number of supermarkets are evaluating the aerofoil technology with promising results. Sainsbury's, the UK's second largest supermarket chain, has been testing the product at a number of its stores. Sainsbury's operates 1,100 stores and uses 1% of the UK's energy in total. As part of its 20x20 Sustainability Plan, Sainsbury's has committed to reducing its absolute operational carbon emissions by 30% by 2020 and this technology can play a key role in achieving this target.

Craig Wilson, Managing Director of Williams Advanced Engineering, added; "Williams Advanced Engineering's mantra is to take the best of Formula One technology and knowhow and work with a range of industries to help improve their products and services. Much of our work focuses on improving energy efficiency and the collaboration with Aerofoil Energy is a perfect example of how Formula One innovations can have a tangible benefit to ordinary people and the environment. This technology has global potential and the savings in operational costs and emissions are extremely promising."
