Phosphating Chemical Filtration Solutions
Phosphating is a chemical process for treating the steel’s surface, where barely soluble metal-phosphate layers are formed on the base material. The layers created are porous, absorbent, and suitable as a conversion layer for subsequent powder coating without further treatment. They are also ideal as temporary corrosion protection if subsequently treated with oil, water, or passivation.
Zinc phosphates build up sludge on the bottom of phosphating tanks. The amount of sludge is related to the number of products processed and the amount of phosphating solution in the system, which is dependent on the size of the tank.
The pre-treatment process used in the surface coating process has small phosphating tanks. Smaller the tank, the lower the volume of processing chemicals that must be heated. Thus, reducing energy consumption.
Our solutions provide the following benefits in the phosphating process-
- Our phosphate sludge separators connect directly to the phosphate tank, and the clean solution returns to the tank continuously.
- Our phosphate sludge separator can remove solid particles up to 5 microns and below at very high efficiency. The separators can work efficiently on Iron, Zinc, Manganese, and zinc phosphate applications and operate at high temperatures.
