Abstract

Chlorine is extensively used for water disinfection in process industries. Due to its properties, however, it can damage downstream process equipment such as reverse osmosis (RO) membranes, and ion exchange (IX) resin units. Therefore, chlorine must be removed as soon as it has performed its disinfection function. Ultraviolet (UV) light represents a powerful technology that has been successfully deployed in several diverse industries such as pharmaceutical, semiconductor, power generation, food and beverage, cosmetics, aquaculture, and healthcare for several decades (Figure 1). The use of UV technology for water treatment has several inherent advantages. UV radiation does not ﾓaddﾔ anything to the water stream such as undesirable color, odor, chemicals, taste, or flavor, nor does it generate harmful by-products. It only imparts energy to the water stream in the form of ultraviolet radiation to accomplish the process of disinfection, total organic carbon (TOC) reduction, or ozone destruction. It is incredibly fast, effective, efficient, and environmentally friendl
