Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.
DBP’s, such as triahalomethanes (THMs), can occur when the natural organic matter (NOM) that is present in the water is combined with chlorine. More specifically, the portion of NOM in the water that is aromatic is the most reactive with chlorine and therefore possesses the most potential for DBP formation. The aromaticity of the organic content in the water is best determined by the UV 254nm water quality parameter.
Therefore, monitoring the aromaticity of the dissolved organics in a water supply by use of Real Tech Inc.’s UV 254nm organic testing instrumentation can serve as an indicator of the potential formation of DBP’s.
