Water treatment installation for a tangential filtration loop
First Claim
1. An installation for the filtering and cleansing of liquids such as water, comprising;
- an ozone gas source; and
a filtration loop with recirculating pump and at least one tangential filtration membrane through which part of the liquid to be treated flows, the filtration membrane having pores with a maximum size of 10 microns, the installation including means for the addition of ozone as an oxidizing gas from the ozone gas source to the liquid to be treated in the loop upstream of the membrane, so as to form microbubbles of said gas with a size such that they create turbulence in the liquid at the membrane, and this turbulence, combined with the phenomenon of oxidation, restricts the clogging of said membrane and leads to an improvement in the flow rate and in the physical/chemical qualities of the filtrate.

Abstract
An installation for the filtration and cleansing of liquids, notably water, of the type having a loop for the circulation of the water to be treated, including at least one tangential filtration membrane, comprising a new tangential membrane filtration installation, with ozone injection, enabling the surface, internal and chemical clogging of the membrane to be restricted. The installation includes means for the addition of an oxidizing gas to the liquid to be treated, in the loop upstream of the membrane, so as to form microbubbles of said gas with a size such that they create turbulence in the liquid at the membrane and this turbulence, combined with the phenomenon of oxidation, restricts the clogging of said membrane and leads to an improvement in the flow rate and in the physical/chemical qualities of the filtrate. If necessary, it includes means for the injecting of chemical reagents and/or absorbents into the filtration loop.
