Abstract

A method of processing the water in a large water region such as a river, dam, lake and marsh is in which a local water processing area is provided for water cleaning, aerating and other purposes, the local water processing area being delimited by a produced water flow produced specific depth and width of the large water region and separating the local water processing area from the remainder of the large water region. The local water processing area may be delimited and separated by a water flow wall or barrier produced by a jet of water or a jet of air, thereby eliminating the need for any physical barrier such as sheet piles or other permanent structure and yet maintaining the continuity between the local water processing area and the rest of the large water region. In addition, the method allows the produced water flow to be localized, providing several advantages over the conventional methods in terms of the obstacleless navigation and less costly implementation.
