The county of New Castle, Del., has awarded a contract to upgrade the ultraviolet (UV) disinfection system at the county’s wastewater facility. The county is installing an ETS-UV system by Neptune Benson. The upgrade will convert the existing chlorine-based system to an advanced closed-vessel UV system. The medium pressure, high-intensity UV disinfection setup has two units. The system will be operational this summer.

Regis Yurcich, director of facilities and maintenance for the county, says county officials were impressed with the advances that have been made in UV technology since the county installed its first UV system, (open channel UV), at one of the county’s other facilities. “The ETS closed vessel systems are fully enclosed, use automatic wipers to keep the sleeves clean, use fewer lamps and are both safer and simpler to use,” Yurcich says.

Ken Rodi, CEO of Neptune Benson adds: “The closed vessel UV systems have been designed to overcome many of the issues encountered by the older open channel technology. The state-of-the-art machines minimize operator maintenance and have UV cameras to measure the performance of the units in real time.”

New Castle County’s Special Services Department and its Environmental Services Division are handling the system upgrade. Environmental Services is charged with ensuring that New Castle County is in compliance with all state and federal environmental laws. Environmental Operations handles the management, maintenance, and repair of all New Castle County sewers, wastewater pumping stations, wastewater treatment plants and county-owned stormwater management facilities. The county has four wastewater treatment plants.
