Installing horizontal UV systems since the 1990s
Glasco has been installing traditional horizontally oriented UV disinfection systems since the 1990s. These systems immerse lamps (protected by quartz sleeves) directly into the effluent.
Systems are designed based on flow rate. Systems can be provided with packaged stainless steel channels or be embedded into concrete. Systems have been biologically validated at the Johnstown UV testing center by HydroQual.
How it works
Water enters a stainless steel or concrete channel. Depending on the flow rate, modules (or banks) will turn on. A Ballast Control Center provides power, controls, monitoring and alarming. Modules are connected to this center to receive Power, Data and Air.
The water passes by the modules where it is exposed to lethal doses of UV light. The lamps are covered via the level control device at the end of the channel (fixed weir, flap gate or downward opening gate).
The modules may integrate an automatic quartz cleaning system, which is pneumatically driven. A UV monitoring sensor is installed in the module and reads the relative output of a group of UV lamps. This sensor is also cleaned during the automatic cleaning process.
