METHOD FOR REGENERATING INORGANIC POROUS PARTICLES, WATER CLEANING METHOD AND CONTINUOUS WATER CLEANING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for regenerating inorganic porous particles, a water cleaning method and a continuous water cleaning apparatus, easily adaptable even to special environment like space environment as a water reutilizing system by safely removing impurities contained in water and steam by using a compact equipment without using any chemical at all. SOLUTION: Inorganic porous particles are regenerated by heating inorganic porous particles to 100-200 deg.C in a reduced pressure state of 10 Pa or less to desorb ammonia and/or amines adsorbed on the porous particles. A composite film, wherein a hydrophilic film is laminated on the surface of a dense film having a cationic group and/or a hydrophobia porous film, is used in the water cleaning method and the continuous water cleaning apparatus.
