Potassium Nitrate
2026-05-28In potassium nitrate production, filtration is required after crystallization or impurity removal to separate solid KNO₃ from saturated brines or contaminated streams. JOECHRE candle filters deliver consistent clarification even with temperature-sensitive…
-
Rare Earth
2026-05-28Rare earth elements (REEs) are chemically similar and difficult to separate, requiring multiple solid-liquid separation steps during processing. After ore digestion using acid or alkaline solutions, DrM filtration systems are used to remove insoluble...…
-
Steel Pickling & Galvanizing
2026-05-28In 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…
-
Titanium Dioxide
2026-05-28Titanium dioxide production by sulfate or chloride processes generates large volumes of slurries that require efficient solid-liquid separation. JOECHRE filtration systems are used to clarify leach solutions, remove residual titanium salts, or separate ir…
