Abstract
Deposition onto the cloths of the exchanged Zeolite and the effect of the particle size of Zeolites in the dispersion system were investigated by using the artificially prepared Ca-Zeolite (Ca-Z) and Mg-Zeolite (Mg-Z).
Main results obtained are summarized as follows :
1) In aqueous Zeolites suspension, the mean particle size of three kinds of Zeolite decreased in the order of Mg-Z > Ca-Z > Na-Z.
In hard water less than 30°DH, the particle size of Na-Z was increased in Mg-containing hard water more than Ca-containing hard water remarkably.
2) In aqueous solutions, with and without surfactant, the deposited amount of Zeolites on cloths decreased in the order of Mg-Z > Ca-Z > Na-Z.
3) After Na-Zeolites were added in Ca or Mg-containing hard water than 20°DH, the deposited amount of Zeolites on cloths increased remarkably in Mg-containing hard water.
4) It was observed that the amount of Zeolites deposited on the cloths and particle size behavior in dispersion system were in good agreement.
