Bauxite and Alumina​

    The Bayer process for refining bauxite into alumina generates red mud and other fine particulate byproducts that require separation during clarification and washing steps. JOECHRE candle filters are used to improve the recovery of dissolved sodium aluminate and reduce residual solids in filtrate streams. Their robust design handles high solids loads and aggressive pH conditions, while automated operation and optional heel volume recovery support efficiency in continuous alumina refining.​
