UV disinfection is a physical process that applies only UV light to the water to render pathogens harmless to humans. It can be used to replace or reduce the traditional use of chlorine as a disinfectant. Chlorine has been shown to have significant environmental impact via toxicity to aquatic life and formation of disinfection by-products (DBPs). Additionally, it presents safety risks to plant operators that handle and store the chemical.
The unique design of the Calgon Carbon C3500™D provides an open channel wastewater disinfection solution using fewer lamps and with reduced head loss. This is made possible by the unique design with rack-mounted delta-shaped wings that provide continual rotation and mixing of the effluent for uniform UV dose application from low-pressure, high-output (LPHO) amalgam lamps.
The C3500™D is completely modular and scalable and can be precisely sized to any application requirement. The control system provides automated closed-loop dose or flow pacing for secondary and tertiary wastewater applications. Additionally, the efficient mixing provided by the delta wing has been proven for demanding reuse and low-quality effluent applications.
The system includes self-cleaning lamp racks, power distribution center (PDC), system control center (SCC), level control and all interconnecting cables.
