A water treatment process comprising a rapid deposition step followed by a filtration step which is performed directly on the micro- or ultrafiltration membranes and corresponding device.

摘要

WATER TREATMENT PROCESS UNDERSTANDING A QUICK DEPOSITION STAGE FOLLOWED BY A FILTERING STAGE THAT IS CARRIED OUT DIRECTLY ON THE MICRO- OR ULTRA-FILTRATION MEMBRANES AND CORRESPONDING DEVICE. The invention relates to a water treatment process comprising a liquid / solid separation step (1) followed by at least one filtration step (2). The invention is characterized in that the solid / liquid separation step (1) comprises a deposition step which is performed at a surface velocity of more than 15 m / h and wherein the filtration step (2) is performed directly on at least one microfiltration or ultrafiltration membrane.
