| Research Abstract |
A new method utilizing particle immobilization in gel is proposed for the treatment of wasted colloidal suspensions. A mixture of alginate aqueous solution and colloidal suspension is added to a calcium chloride aqueous solution, resulting in calcium alginate gels. The gel suspension is drained gravitationally, followed by mechanical expression of the gel particles. During the expression, the colloidal particles remain in the gels and the expressed liquid is clear. This method can be extended for the treatment of nanocolloidal suspensions, dissolved matters, and non-aqueous colloidal suspensions, provided that appropriate substances are added to the colloidal suspensions.
