Consideration for long-term storage of a spent zeolite adsorption vessel, 11; Evaluation for water retention performance of zeolite

Arisaka, Makoto ; Yamagishi, Isao 

The water retention performance of zeolite was evaluated on the basis of a water level in cylindrical container filled with zeolite and artificial sea water. The water level was measured with a following procedure; (1) the mixture of zeolite and artificial sea water was filled in a clear cylindrical container, (2) artificial sea water was discharged through the drain, (3) after the discharge stopped naturally, the water level was measured by watch. It was found that there was a positive correlation between the water level and the bulk density of zeolite.
