Steel Pickling & Galvanizing

    In steel surface treatment, filtration is used to remove iron salts, oxides, and other solids from spent pickling or galvanizing solutions. JOECHRE candle filters operate in closed loops to clarify acid-based baths or rinse waters, enabling their reuse or safe discharge. Their corrosion-resistant construction and ability to handle high temperatures and low pH make them a strong fit for continuous metal processing lines. Automatic cake discharge reduces downtime and operator exposure in harsh chemical environments.​
