Water & Wastewater Treatment

TECHNICALLY SPEAKING 34 Water & Wastewater Treatment March 2014 wwtonline.co.uk a second unit designed and constructed at Davyhulme in early 1921 to treat a dry weather flow of 4,546m 3 /d (1M gallons). Originally Fowler wanted the process to be freely available, but as the commercial potential became apparent, he was persuaded to let Walter Jones of Messrs Jones & Attwood patent it. Innovative contract Jones & Attwood won the majority of the new works partly because of their novel form of contract. They installed the plant at their own risk and the client only took it over when it had demonstrated its worth, based on the effluent quality. The first full-scale activated sludge plant was built at Worcester in 1916. In 1919, Jones & Attwood transferred all of the activated sludge work to a new company, Activated Sludge Limited, based in Westminster. It proved to be a very litigious venture and in the late 1920s it filed suits for patent infringements against Chicago, Milwaukee, Cleveland and a number of smaller cities. The success of these suits meant that uptake of the process stalled until the patents expired in the late 1940s. Since the patents expired, the activated sludge process has been the dominant technology worldwide for large, urban treatment plants. It has seen many process advances: nitrogen removal, phosphorus removal, dissolved oxygen control and improvements to sludge settling characteristics, but in the performance of its basic function of biological oxygen demand (BOD) removal, it has changed little over the past century. It worked very well when it was first developed, and it works about the same today. Later life Ardern and Lockett, its acknowledged inventors, both led distinguished research careers and each went on to become presidents of the Institution, Edward Ardern in 1929-30 and William Lockett in 1942. Ardern remained at Manchester until his retirement, but Lockett moved on to become the chief chemist of the Middlesex County Council Drainage Department (now Thames Water) in the early 1930s. As with all great inventions, there comes a time, a place and people. The intellectual setting at Davyhulme provided by Fowler proved the ideal environment for the practical and talented chemists Ardern and Lockett. nnn To commemorate the achievements of Lockett, Ardern and Fowler at Davyhulme, CIWEM's Wastewater Management Panel, in cooperation with Aqua Enviro, is organising a centenary event on 2-3 April with an option to visit Davyhulme on 1 April.

OUTSTANDING PERFORMANCE. OVER 100-YEAR HERITAGE. MOVING ON UP Water underpins Iraqi partnership The University of Leicester (UL) is working in collaboration with Soran University in the Kurdistan region of Iraq to establish an International Centre for Natural Resources Research. According to the two universities, the Centre aims to tackle the water supply and quality challenges Kurdistan faces against the background of rapid development of the region's infrastructure and tourism industry. Researchers from both institutions will come together to carry out research in the fields of water resources, sustainability, food security and geographic information systems. Professor Heiko Balzter, director of the University of Leicester's Centre for Landscape & Climate Research, said, "This is a hugely important bilateral agreement. Soran University is a new University in the Kurdistan region of Iraq, which is rapidly developing now that the long history of armed conflicts in the region is over. "From our side, we are committed to supporting University staff and students in Soran in their professional development. Our aim is to build mentoring partnerships between staff, deliver block courses locally to contribute to higher education in the region, to deliver staff development activities, and to develop joint research projects together." Professor Martin Halliwell, deputy pro-vice chancellor, of UL, said, "We are delighted that the University is currently training over a hundred Kurdish students and will be able to take back best practice and subject knowledge to the region."
