摘要: A method for removing suspended impurities and colored substances from water which is hard and/or has a pH in excess of 5 comprises contacting the at its natural with coagulant/adsorbent finely divided particulate mineral material, individual particles have thin hydroxylated surface layer having positive zeta potential adsorption pH, separating thus treated coagulant/adsorbent.
