CST has announced its introduction of Berson’s InLine UV waste water disinfection systems. These systems have previously been installed on the island of Aruba, where eight are used to disinfect drinking water and two are used to treat greywater prior to discharge. The island opted for five UV systems instead of using chlorine as part of its ‘non-chemical’ approach to water treatment. Following a desalination process, the water passes through the UV systems. The units are installed outdoors and controlled by DGtronic microprocessors, with each disinfecting 400m3 of water per hour, rising to 600m3/h during peak flow conditions. No chlorine is used at any stage of water the treatment process. Berson’s compact InLine medium pressure UV systems use MultiWave lamps, which emit a wide spectrum of UV wavelengths with a very high energy output, causing the total and permanent deactivation of microorganisms. The small size of the lamps means that they are positioned perpendicularly to the flow of liquid, increasing disinfection efficiency and reducing the overall size of the disinfection unit. Berson's InLine+ medium pressure closed vessel UV systems recently gained formal approval for wastewater reuse applications.
