Control Your Chlorine Costs

Jun 17 2008

Grundfos Alldos electro-chlorination products have secured a four year
contract to supply chlorination services to the UK’s largest water only company Three Valleys Water, part of the Veolia Group, that delivers 890 million litres of tap water each day to 1.2 million customers in North London and the Home Counties.
Alison Winser a buyer with Three Valleys said; “Selcoperm lectrochlorination systems have been used for many years and this framework award is based on their ability to offer a safe & reliable system for generating hypochlorite onsite from salt, a competitive pricing schedule, low whole life costs backed by a very strong service & support culture.
We have ensured that Grundfos Alldos can cater for virtually all our
current requirements but equally important is the innovative R&D
approach that they are taking in looking to the future with their self contained electrochlorination systems, both small & large, that offer aspects that will be important to Three Valleys Water.”
The Framework is effective for a four year period to September 2011.
Selcoperm Electrochlorination systems are ATEX compliant and are Approved for Use in Public Water Supplies.
Standard equipment is available from 25g/h to 2kg/h with larger project
engineered packages taking the range to 20kg/h including salt saturators, large volume product tanks and the associated chemical dosing systems.
In addition to use within the water industry, electro-chlorination is gradually gaining ground over traditional chlorination methods as there are for operators and risk assessors a few niggling worries about the handling, transportation and storage of chlorine-related chemicals, which are, classed as hazardous substances.
Which is why Gaffey Technical Services Ltd recently installed a Grundfos Alldos Selcoperm electro-chlorination system at the University of Bath.
Electro-chlorination is the safest way of chlorinating a pool as it eliminates the risks involved in transporting, storing and handling chemicals. Operators needn’t wear protective gear and they won’t inhale any chlorine odour in the plant room. Also bags of salt are a lot
easier - and safer - to store than drums of hypochlorite. They’re cheaper to transport too.
