30/09/2016  This is also one of the significant uses of power boiler fly ash for treating the pulp and paper mill wastewater. In the case of using fly ash as an adsorbent, the metal salts get hydrolyzed in the presence of natural alkalinity to form metal hydroxides. The multivalent cations present in the fly ash can reduce the zeta potential value, while the metal hydroxides are good adsorbents. The carbon content of fly ash is significant, because the effectiveness of fly ash
