The invention concerns an underwater water treatment unit which has specific cleaning means which are suitable for cleaning filtration membranes in the unconventional conditions associated with use at great or very great depths, as well as a method for cleaning the membrane of the underwater water treatment unit.

Underwater water treatment unit and method for cleaning said unit

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.
