High-pressure water cleaning is widely used in the cleaning of various water pipelines, heat exchangers, cooling towers, and pressure vessels. This technology was introduced to the alumina industry around 2005.
With advancements in plunger pump pressure and flow rates, as well as improvements in actuating systems, it has gained increasing recognition and adoption among alumina producers. It is specifically designed to remove hardened bauxite dust from equipment and clean alumina evaporators, filters, digesters, tanks, containers, and sewers.
