An increasingly popular de-chlorination technology is ultraviolet (UV) treatment. High intensity, broad-spectrum UV systems (also known as medium-pressure UV) reduce both free chlorine and combined chlorine compounds (chloramines) into easily removed byproducts.
In pharmaceutical industry, many water treatment systems include RO units, which commonly use thin-film composite membranes because of their greater efficiency. However, these membranes cannot tolerate much chlorine, so locating the UV unit upstream of the RO can effectively dechlorinate the water, eliminating or greatly reducing the need for neutralizing chemicals or GAC filters.
Additional benefits of using UV de-chlorination are:
•High level of UV disinfection;
•TOC destruction;
•Elimination of risk of introducing microorganisms into RO (via GAC or injection of neutralizing chemicals);
•Overall improved water quality at usage point.
UIEX produces special sanitary components in AISI 316L to fit pharmaceutical water treatment systems and industrial lines, such as the MP series UV, a wide range of UV Reactors and Control Units offering advanced technical features for following applications: germicidal action, Ozone removal, TOC decrease, Chlorination removal.
