In-Pipe UV Disinfection of Wastewater - The Advantages
More and more operators of wastewater treatment facilities are now opting for in-pipe, medium pressure UV disinfection systems. They are choosing this technology in favour of older open-channel, low pressure UV systems.The reasons for this change are due in part to the drawbacks of open-channel technology, as well as the advantages of in-pipe systems. The disadvantages of open-channel, low ...

Bugs Killed by Medium Pressure UV Stay Dead
It is well known that bacteria and other microorganisms contain enzymes that can repair UV-damaged DNA, a process known as 'reactivation'. Some of these enzymes need visible light to perform the repairs ('photoreactivation'), while others can do so without light (known as 'dark repair'). Photoreactivation is generally quicker than dark repair, but both of these phenomena pose obvious problems ...

What is the difference between Low pressure UV and Medium Pressure UV lamps?
Both low pressure and medium pressure UV systems exploit the power of UV radiation. However, there is a huge difference in their technology and effects they have on the treated water. In this article we aim to explain why UV is not always the same UV and also why it is crucial to distinguish these two technologies. As producers of both technologies, low pressure and medium pressure UVs, we can ...

Water treatment: mimicking earth’s hydrological cycle
Water treatment and water treatment technologies are an essential line of defense to remove contaminants and bacteria before the delivery of clean, potable water supplies for consumption. Water sources can be subject to contamination and therefore require appropriate treatment to remove disease-causing agents. Public drinking water systems use a variety of methods to provide safe drinking water ...
