UV irradiation can be used for multiple purposes in water treatment, but is primarily employed as a disinfection process that inactivates waterborne pathogens without chemicals. For other applications, UV is used for the removal of organic and inorganic chemicals, including chlorine, chloramines, ozone and Total Organic Carbon (TOC). When combined with oxidants such as ozone or hydrogen peroxide, or semiconductors such as titanium dioxide, UV can be used for the oxidation of refractory chemicals such as chlorinated solvents, taste and odor compounds, and other emerging contaminants.

Our UV systems incorporate multiple lamp technologies such as low-pressure and medium-pressure; multiple lamp orientations such as horizontal and vertical; and multiple reactor designs such as open-channel and closed-vessel.

Advantages of UV Technology
UV disinfection has been successfully applied worldwide for decades, and has numerous advantages over chemical disinfection methods:

• Effective for all types of microorganisms, including bacteria, viruses, fungi, and protozoa such as Cryptosporidium and Giardia
• Chemical-free technology, eliminating chemical transport, storage, handling or removal
• Non-corrosive and no hazards associated with accidental overdosing
• Low capital and operating cost
• Easy to operate and maintain
• No disinfection by-products (DBPs) of health concern formed
• Compact and easy to retrofit
• Efficacy is independent of pH
• No impact to the aesthetic quality of the water (taste, odor, color)
• Safe and environmentally-friendly
