BACKGROUND
Ultraviolet (UV) technology has been used in the treatment of municipal wastewater for decades to ensure that discharge to local lakes and rivers is compliant with discharge permits, and local regulations. UV acts by inactivating microorganisms and reduces the various coliform, E. coli, or heterogenous plate counts used to evaluate discharge.

Chemical-based technologies such as free chlorine are known to form treatment by-products which are harmful to

Groundwater pumping in the Los Alamitos, California area over the last century has caused groundwater levels to drop, allowing seawater to intrude into the local groundwater aquifer. To prevent additional infiltration by seawater, a coastline barrier of wells injecting fresh water has been in place since 1965. Until recently, imported potable drinking water was injected into the aquifer. However, the Alamitos Barrier now utilizes highly-treated, recycled water for this application. One obstacle

The PWN Water Supply Company located in the North Holland Province of the Netherlands, uses Trojan UV technology to provide an additional barrier to micropollutants. In addition, the UV system disinfects, inactivating chlorine-resistant pathogenic microorganisms. The drinking water treatment plant, located in Andijk, serves approximately a half a million people and treats up to 4,000 cubic meters per hour (or approximately 25 million gallons per day). It is the largest drinking water facility i
