This is a surface treatment process in which a stream of high pressure water is mixed with abrasive particles which aredirected on to the surface to be treated. This method is used to remove paint, metal scales, rust, salt and other contaminantsfrom the surface. The velocity of the water jet along with hardness, density, toughness and particle shape of theabrasives will create a surface prole to provide a suitable surface for painting.Fluidtech oers high pressure water jetting pump sets with venturi nozzles which are mounted on to the water jettingguns which mixes water with the abrasives. This method is called wet sand blasting which oers a pollution freewaterabrasive operation.
