Pool water gets the UV treatment
August 1st 2007 Independent tests carried out by WRK Design and Services, a chemical engineering consultancy, at the Lightwaves Leisure Centre in Wakefield showed a dramatic reduction in TOC (total organic carbon),THMs (trihalomethanes) and combined chlorine in pool water following the installation of a Hanovia medium pressure UV system.
The main objectives were to analyse swimming pool water samples for TOC,THMs, active/free chlorine and TDS (total dissolved solids) before and after installation of a UV water treatment system.
WRK concluded "The results of the analysis indicate that the medium pressure UV system at Lightwaves Leisure Centre was beneficial in reducing the TOCs and THMs to very low levels (~25 µg/L) up to 14 days after installing the UV system." The report also confirmed the reduction in combined chlorine was significant. More articles from Hanovia Limited: |
