Water desorption system

The stripping or desorption process is an established and reliable process for which Likusta offers systems for drinking-water treatment or groundwater treatment. According to the principle of desorption, pollutants are separated from contaminated water and transferred into the gas phase. Depending on the application, gas treatment then follows with an activated carbon filter. A typical application for desorption systems is the deacidification of drinking water by reducing the concentration of carbon dioxide dissolved in the water. This serves to prevent the transfer of undesirable substances from drinking-water pipes into the drinking water, to improve the subsequent preparation processes, or to protect the system components against increased corrosion. On the other hand, desorption systems are used for the removal of dissolved hydrocarbons used in the manufacture or industrial use of e.g. solvents, hydraulic oils, adhesives or varnishes, refrigerants and pesticide products. These substances are oftentimes highly toxic, carcinogenic, and can alter the genetic make-up of humans and animals when they are consumed, for example through drinking water. This includes: Lightly volatile aromatic hydrocarbons (BTEX), e.g. benzene, toluene, ethylbenzene, xylenes Lightly volatile chlorinated hydrocarbons (LCC), e.g. trichloroethene, tetrachloroethene, cis-1,2-dichloroethene, 1,1,1-trichloroethane Aliphatic ether, e.g. methyl tert-butyl ether (MTBE) How the system works In the desorption system the contaminated water is trickled onto the filling bodies through a central nozzle or a perforated distributor plate in the upper part of the column.
