The Upstream range  from Nubian Water Systems includes six different ultra violet water treatment systems designed to disinfect water at different flow rates, depending on usage and the type of water being used which includes recycled grey water and water from deep wells. The unique system consistently delivers the highest possible dose of ultra violet rays through proprietary high-output lamps.

The latest features of the Upstream include an automatic purge valve that ensures fouling will not occur in low or non flow conditions; problem diagnosis and recording; and stainless steel, aluminium, and impact proof ABS plastic housing.

The Upstream is not a certified Class A product; however it has been laboratory tested at 50% and 75% UV transmittance. The use of Crossfire technology removes the risks associated with conventional UV systems, and ensures safe, pure water with every use.
