WO/2014/142638 WATER PROCESSING SYSTEM||WO||18.09.2014|
||PCT/LV2014/000003||SIA "RR FISH"||TJUTJUNNIK, Andrei|
A system and method for processing impure water is achieved by using ozone for the separation and removal of certain contaminants and for further purification of the water. According to one embodiment, a gas comprised of ozone and air is injected into the impure water. The gas is converted to bubbles which are used as a flotation reagent while the ozone portion of the gas provides for the disinfection and deodorization of the liquid. The impure water is constantly supplied into an upper portion of a working volume or column of fluid contained within a processing unit. At the same time the gas is supplied into the bottom part of the same fluid column through one or more diffusers. Due to their porosity the diffusers generate the bubbles of this ozone-based gas so that each bubble has a predetermined size. ˙
