Water clarification |
| abstract |
A B S T R A C T "WATER CLARIFICATION" A method for removing suspended impurities and coloured substances from water which is hard and/or has a pH in excess of 5 which comprises contacting the water at its natural pH with a coagulant/adsorbent which comprises a finely divided particulate mineral material, the individual particles of which have a thin hydroxylat-ed surface layer having a positive zeta potential at the adsorption pH, and separating the thus treated water from the coagulant/adsorbent. |
