Abstract

(Procedures with its washing device with water for continuous filter of horizontal filtration surface and cells,) washing carried out after the discharge of the filter cake, characterized in that it uses water jets at high kinetic energy and/or drains of Strongly turbulent water to cause mechanical abrasion of the deposits and any incrustations formed on at least the walls of the filters and the filter cloths at the time of filtration and to mechanically drag these deposits and/or these scale.
