S. Roberts Co. is very proud to represent Calgon Carbon UV Technology in the states of MN, ND, SD.   Soon to have a very nice installation in Minot, ND (MWH/Houston Eng)

Then soon after, Calgon Carbon became the first company to adapt the technology to cost-effectively inactivate pathogens in surface water. These breakthroughs have established Calgon Carbon as a world leader in the use of UV technology for disinfection and oxidation to treat drinking water, wastewater, groundwater, process water and ballast water.

Features & Benefits:

When contaminated water is channeled by UV lamps with germicidal properties, UV energy disrupts the DNA in viruses, bacteria and protozoa, rendering them harmless. When combined in water with oxidizing agents such as hydrogen peroxide, UV light generates highly reactive radicals that oxidize organic contaminants, creating a cost-efficient treatment regimen.

Compared to chemical treatment of water, UV technology is low-cost and environmentally friendly, and eliminates the need to transport, store or handle toxic chemicals. It generates no DBPs, which further safeguards the environment and aquatic life.

Calgon Carbon UV systems span five continents and treat more than five billion gallons of water each day.

The Stage 2 Disinfectants & Disinfection Byproducts Rule (DBP) is designed to limit the formation of several byproducts of conventional disinfection, such as Total-trihalomethane (TTHM), Haloacetic Acid (HAA5), Chlorite, and Bromate. Several of these byproducts are either known to be or are suspected to be a carcinogenic.

The EPA uses the mandate of the Safe Drinking Water Act to monitor emerging contaminants, under the Unregulated Contaminant Monitoring Regulation (UMCR2).UV light is used successfully to remove Methyl-t-butyl ether (MTBE), a fuel oxygenate that causes unpleasant taste in water. Likewise N-Nitrosodimethylamine (NDMA) is removed using UV light. NDMA is toxic and is suspected to be a carcinogen.

UV is used as a primary disinfectant for all water-borne organisms. UV is used to photolyze contaminants. As the number of emerging pathogens increases, and as more contaminants need to be controlled, the demand for UV will grow.

Systems are installed in line either vertically or horizontally. The footprint is normally a key factor, as pipe galleries are usually very tight and cramped.

Emerging contaminants are all targets for AOP application; these Advanced Oxidation Processes use the combination of H202 and UV, or occasionally Ozone and UV. AOP processes are also used successfully to remove taste and odor contaminants from surface water, such as Geosmin and MIB.
