Water clarification |
| abstract |
A B S T R A C T A particulate coagulant/adsorbent for removing suspended impurities and coloured 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 having 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. |
