The present invention is a filtration system and a method for cleaning a filtration system. The filtration system comprising a hydraulic circuit Cp recycling the permeate stream to the feed side of the membrane and/or a hydraulic circuit Cr recycling the retentate stream to the feed side of said membrane. The method injects an amount of a chemical product into the filtration system in the hydraulic circuit Cp or in the hydraulic circuit Cr or upstream of the cross-flow filtration membrane, setting the proportion of recycled permeate stream or recycled retentate stream collected in the hydraulic circuit Cp and/or Cr to enable the recycling of a significant amount of unreacted chemical product having passed through the cross-flow filtration membrane to the feed side of said cross-flow filtration membrane.

Cleaning method of a water-filtration system under operation

A method for testing an underwater filtration system as well as the underwater testing device which enables the operation of filtration systems in aquatic conditions. The testing method includes introducing a flow of water into the underwater testing device via a water inlet, said underwater testing device including at least one filter, bringing said flow in the underwater testing device up to said filter, obtaining a filtrate downstream of said filter and discharging said filtrate into the environment via a discharge pipe. The underwater testing device is placed underwater at a depth of at least 500 meters.
