The Salcor Model 3G ultraviolet disinfection unit is specifically designed for disinfecting the effluent from aerobic treatment plants. It is able to reduce fecal coliform bacteria levels well below the most stringent US treatment standards.
A Salcor 3G unit was tested in OSET Trial; 13, Rotorua 2017-18. See OSET-NTP Trial 13 Performance Certificate Environment Technology AES-38 R and R UV.

How it Works
The 3G disinfection chamber is fixed directly to the aerobic plant (septic tank) discharge pipe and is permanently installed below ground. The ultraviolet light source for disinfection is mounted in a sub-assembly which can be inserted or removed through the top of the riser pipe for periodic servicing. The light source is mounted in the centre of an anodized aluminum frame which divides the disinfection chamber in half. The frame seals against the inner surface of the disinfection chamber to prevent flow bypass. When fully inserted, the disinfection sub-assembly is properly located by two pins mounted near the top of the disinfection chamber. The disinfection subassembly causes the wastewater entering one side of the unit to flow vertically downward, make a 180 degree turn, and then flow vertically upward and out the other side of the unit. This well-defined flow path is designed to give the fluid proper exposure time and no short circuiting. The ultraviolet light source is surrounded by a clear fused quartz tube to control the lamp surface temperature.
When the disinfection chamber is filled with water, the ultraviolet light source can operate continuously, whether or not water is flowing. Continuous operation with a lamp surface temperature range of between 40 and 49 degrees Celsius provides optimum ultraviolet light output and long lamp life.
The electrical subassembly is mounted in a junction box located on top of the 10cm riser pipe. The box contains fuses, alarm circuitry, UV lamp ballast, power cable connections, voltage surge protection, and electronic noise filters. The Salcor Model 3G alarm relay circuit triggers an external alarm to warn the user when the UV lamp is not operating properly. When the UV lamp is producing ultraviolet germicidal light at a safe level, a green LED indicator light, located on the top of the electrical junction box, glows indicating proper UV lamp operation. The light stops glowing when the light output from the UV lamp falls below a safe level or is not operating.
