Dechlorination equipment saves P and G GBP45,000
Since installing Hanovia ultraviolet dechlorination equipment, Procter and Gamble USA has reduced the cost of maintaining reverse osmosis membranes by GBP45,000 per annum
It is then passed through carbon filters and is deionised before UV disinfection.
The UV systems have the capacity to treat up to 80 tonnes of water per day, 24 hours a day.
"UV was specified as an integral part of the purified water system right from the start," commented a senior technician at the site.
"Due to the nature of the production process and associated regulatory requirements we can't use chemicals, and Ozonation was rejected due to the downtime related with retro-fitting.
UV was therefore considered as the best solution as it is non-intrusive and a tried and tested microbial control technology.
It is also low-maintenance, the only intervention required being infrequent lamp changes", he added.
