In a continuous drive to reduce sludge volumes and increase energy efficiency by converting biogas into electricity and generating carbon credits, Thames Water are to install a 24 kW Dirk IWE.tec part stream ultrasound system at its 300.000 PE Hogsmill STW. It is expected that the installed system will save Thames Water an annual £140,000 on disposal costs and has the potential to generate up to 200kW extra energy, as well as improving the characteristics of the product.
This will be the first full scale ultrasound installation in the UK. The Dirk-IWE.tec system has already been installed at full-scale in 20 Wastewater Treatment plants throughout Europe and Japan, the first systems were installed 4.5 years ago, and many water companies are now placing repeat orders.
