PROBLEM TO BE SOLVED: To provide an inexpensive flocculation method capable of developing a rapid flocculation effect and capable of treating a hardly treatable liquid incapable of being separated into water and a solid component by the present technique. SOLUTION: A predetermined amount of an alkali metal silicate is preliminarily added to seawater and the silicate brought to a gelled state is dispersed in seawater as flocs to obtain gelled water. This gelled water is added to a liquid to be treated. COPYRIGHT: (C)2005,JPO&NCIPI
