Verfahren zur Filtrierung und Reinigung von Wasser.

摘要

The field of the invention is that of plants for the filtration and purification of liquids, especially water, of the type comprising a loop for circulating the water to be treated, including at least one tangential filter membrane. …The objective of the invention is to provide a new filtration plant with a tangential membrane with ozone injection, making it possible to limit the surface, internal and chemical blockages of the membrane. …According to the invention the plant comprises means (2) for adding an oxidising gas to the liquid to be treated, in the loop upstream of the membrane so as to form microbubbles of the said gas of such size that they give rise to turbulence in the liquid opposite the membrane which, when they are coupled with the oxidation phenomenon limit the blocking of the said membrane (1) and result in improvement in the flow rate and in the physicochemical properties of the filtrate. If appropriate, it comprises means (10) for injecting chemical reactants and/or adsorbents into the filtration loop. ……
