The system utilizes two parallel Trojan D30 reactors which contain low pressure amalgam ultraviolet (UV) lamps. Each train contains flow control capability. This involves allowing the lamp output to be reduced. This minimizes over dosing and conserves power when the UVT is high or the flow is low.
We procured the UV system based on a life-cycle cost analysis between medium pressure and low pressure UV system. This approach resulted in the selection of the power modulating amalgam lamp system.
Opus DaytonKnight coordinated with the local health authority for selection of the approved validation protocol. The system is validated based on the USEPA criteria for a dose of 40 mJ/cm2.
