Zusammenfassung:The present invention relates to a process for filtering a strongly alkaline solution of at a high temperature, particularly a sodium aluminate solution (NaAl(OH)4) to remove solid impurities therefrom in an environmental-friendly and efficient manner, which comprises feeding the sodium aluminate solution containing solid impurities to a porous ceramic micron filter to filter said solution under an applied pressure; collecting the filtrate and storing a portion of the filtrate in a storage tank; and discharging the retentate from the ceramic micron filter.
