The Tri-State Wastewater Equipment International, LLC. Horizontal Channel Type Ultraviolet Disinfection Systems has the capability to disinfect gravity fed wastewater flows of up to one million gallons per day. Larger capacity requirements can be handled by our vertical-style series. The Tri-State Wastewater Horizontal Channel Type’s most significant features are its ease of installation, operation, and the small footprint.

The Tri-State Wastewater ultraviolet disinfection (UV) system comes standard with a stainless steel channel and built-in level control weir, remote-mounted NEMA 4X modified stainless steel power control center with a window kit and removable waterproof modules.

Connection Options
When designing an Ultraviolet Disinfection system into the overall wastewater treatment plant (WWTP), it is required to connect to the inlet and from the outlet of the UV system. The connection options are as follows:

Standard U-Channel pattern with bolt connection (shown as our standard configuration) provides a square connection and is typically used for bolt-on mount for structural steel walls, concrete channels, or for custom connections.

Transitions plates can be bolted to the U-Channel to allow for pipe stub, threaded pipe or flanged pipe connections.

Transition boxes can be bolted to the U-Channel pattern. The boxes can have 150# flanges, flange patterns, pipe stubs or threaded pipe connections. The transition boxes are used to connect to piping where high or turbulent flows are expected. The transition boxes help to de-energize and baffle the wastewater to create a more even flow.

Operation and Maintenance
In order to meet the discharge permit, the system will require maintenance. Lamps will need to be replaced every 8,500 hours. Due to the heat of the lamps and the harsh nature of the wastewater, the quartz sleeves (the protective material over the lamps) will also need to be cleaned. The cleaning regime will be directly related to the pre-treatment, the makeup of the wastewater and access to personnel. Fouled quartz sleeves will prevent the UV light from penetrating the wastewater and thus will reduce system efficiency. An operator is required to remove the modules and clean the quartz sleeves with a lime, calcium or rust remover. This can be done on a work table or on a cleaning rack.
