Lighting

    Advanced lighting applications such as LED and phosphor production require reliable filtration of suspensions, rare earth materials, and chemical intermediates. JOECHRE filters are used to purify metal hydroxides and oxides, remove reaction by-products, and support wash cycles during slurry preparation. The systems operate under low-shear conditions, preserving particle morphology where needed. Optional cake washing steps enable recovery of valuable materials and reduction of impurities before drying or calcination. Filter internals can be selected based on chemical resistance and compatibility with high solids content.​
