Phosphate coating is a surface treatment that involves applying a thin layer of phosphate to metal surfaces. The process begins with cleaning and degreasing the metal surface, followed by the application of a phosphate-containing solution. It is widely used in all industries that use metal, especially in automotive, aerospace and construction.
Phosphate coating processes are generally degreasing and cleaning, rinsing, rust and descaling, activation, phosphating, finishing (neutralization or passivation).
Treatment of phosphate coating wastewater,
For the safe and legal treatment of these wastes, GESU Environmental Technologies uses appropriate processes. Treatment processes include steps such as adjusting the pH levels of the wastes, removing the metal substances in the wastes and making the wastes miscible with water.
