Abstract

Official abstract text for this publication.

A water treatment method is provided. The method includes filtering water in a membrane filtration unit including at least one membrane filtration module, collecting a permeate and collecting a retentate at the outlet of the membrane filtration module, withdrawing solid materials and/or hydrocarbons contained in the retentate, in order to provide a treated retentate, recycling the treated retentate at the inlet of the membrane filtration module, and providing a treated water flow from the permeate from membrane filtration module(s). An installation adapted for applying this method is also provided.

First claim

Opening claim text (preview).

The invention claimed is: 1. A water treatment method, comprising the following successive steps: (i) filtering water in a membrane filtration unit comprising at least one membrane filtration module, the water containing hydrocarbons in an amount of up to 1000 ppm and suspended solid materials in an amount of up to 200 mg/L; (ii) collecting a permeate and collecting a retentate at an outlet of the membrane filtration module(s); (iii) withdrawing at least one of: (a) solid mate…
