Severn Trent Acquires Quay

Severn Trent Services has announced the acquisition of the business of Quay Technologies Ltd. of Berks, United Kingdom, manufacturers of a proprietary ultraviolet (UV) technology for use in water and wastewater disinfection. Quay Technologies’ patented microwave-powered UV systems offer significantly improved reliability and bulb life, resulting in lower overall operating costs when compared with traditional technologies. Severn Trent Services will offer the Quay UV systems to the water and wastewater treatment market under the new brand name, MicroDynamics.

Since 1998, Quay Technologies has provided UV solutions to municipal water and wastewater clients. MicroDynamics’ microwave technology enables the use of electrodeless bulbs, dramatically increasing system efficiency and bulb life when compared to traditional UV lamps. All systems are modular, with a small footprint, and use the same parts and components for easier maintenance and lower operating costs. The operating costs of MicroDynamics systems can be as little as half of competing UV technologies, primarily driven by significant reductions in maintenance costs. The company supplies both closed-vessel and open-channel systems.

In wastewater applications, UV disinfection is highly effective on all bacteria and viruses and may also be effective in combating endocrine disrupters. In drinking water applications, UV technology is used in the treatment of chemical contamination and in the treatment of bacteria and viruses, including cryptosporidium.
