ABSTRACT:
In case where a surface active agent is contained in waste water, it is extremely difficult to remove the surface active agent, and the present invention has previously found that the surface active agent is oriented and adsorbed in the periphery of colloidal particles, by making use of the fact that an association property exhibits when a concentration exceeds a micel concentration, whereby the periphery of the particles are partly made to increase the concentration to a level above the micel concentration to adsorb and remove the surface active agent in the waste water. The treating agent for that purpose is produced by emulsifying oil, montmorillonite and the like and adsorbing soda of fatty acid or potash salt thereto.
