WILTSHIRE, UK, May 17, 2007 -- WRc Group is currently working with six UK water companies on a collaborative project that will provide guidance to those planning investment in chlorination systems. Chlorine is a key chemical for the UK water industry: its primary use is in the disinfection of drinking water prior to distribution to consumers. Systems for dosing chlorine are mainly based on one of three sources: chlorine gas obtained from liquid that is delivered to site in pressurized containers; aqueous sodium hypochlorite (up to 15% by weight chlorine equivalent) delivered to site in carboys, IBC or bulk, or dilute hypochlorite (about 1% w/w chlorine equivalent) manufactured on site, as needed, by electrolysis of brine.
Stricter regulation of the handling and use of chlorine gas, rationalization in the UK chlorine market (Ineos Chlor is now the sole UK manufacturer), improvements to the proprietary systems used to generate hypochlorite on site, and many other changes, mean that identifying the right system for a given application is now much more complex. This WRc-led project will review the key chlorine technologies in terms of operating costs, whole life costs and wider strategic implications. Up to date guidance will be provided to those planning refurbishment or replacement of chlorine systems, as well as those with responsibility for contingency planning and developing the next 5 year business plan.
