Embodiment Construction

[0054] refer to figure 1 and 2 , the embodiment shown has two interconnected devices 1 , 1 ′ according to the invention. Each of these devices comprises: an input part 3 for the liquid to be filtrated with an input conduit; means for reverse osmosis filtering said liquid described below, which communicates with a discharge means also described below for discharging the liquid thus filtered; And a concentrate discharge part 5 with a discharge duct.

[0055] Each device 1, 1' comprises a chamber 6 with a body 6a, a hemispherical end 7 and a cylindrical base 8 common to both devices 1, 1'. The chambers 6 of the two devices 1, 1' have a common space. These chambers 6 are made of steel, which allows to withstand pressures up to 80 bar and is coated with an anti-corrosion coating.

[0056] In each cylindrical chamber 6, a plurality of strings of reverse osmosis membrane filter modules 2 are installed, which are installed parallel to each other in the housings provided for this p...

Abstract

Device (1) for pressurised liquid filtration, said device comprising a plurality of series of membrane filtration modules (2), means for conveying (3) liquid to be filtered, means for evacuating (4) filtered liquid, and means for evacuating (5) concentrate, characterized in that it comprises a pressurised common cylindrical chamber (6) accommodating a resin-based structure provided with longitudinal housings (9a) parallel with one another, within which said series of membrane filtration modules (2) are arranged.

Description

technical field [0001] The field of the invention is that of the design and manufacture of equipment for press filtration of liquids using membrane filtration modules. [0002] The present invention relates particularly, but not exclusively, to such apparatus for filtering brackish or brine water to produce potable water. [0003] The present invention not only relates to equipment using microfiltration modules, but also equipment using ultrafiltration modules, nanofiltration modules or reverse osmosis filter modules. However, the invention applies in particular to the scope of implementation of plants using reverse osmosis filter modules. Background technique [0004] Different methods are known in the prior art for pressing liquids to purify them. Among these technologies, especially in the production of drinking water or in the production of process water, membrane filtration technology is used extensively. These membranes have a porous structure that allows the membra...
