초록

A particulate coagulant/adsorbent for removing suspended impurities and colored substances from water by coagulation comprises a finely divided particulate mineral or clay material, the individual particles of which have been treated to produce a thin hydroxylated surface layer haivng a positive zeta potential at the adsorption pH. A process and an apparatus for water treatment utilizing the coagulant/adsorbent and providing for regeneration and recycling thereof are also described.

청구항

A process for the clarification of water which comprises the steps of: (a) contacting water at pH 3-5 with a coagulant/adsorbent consisting of a finely divided particulate mineral or clay material, the individual particles of which have a particle size of 10 microns or less and have a thin hydroxylated surface layer which has a positive zeta potential at the adsorption pH; (b) separating the water from the coagulant/adsorbent to obtain the clarified water; (c) treating a suspension of the spent coagulant/adsorbent to raise the pH to about 10.5; (d) sepa...
