Abstract:
A process for production of potable water suitable for distribution and consumption from a raw water source containing humic and fulvic acids, said process comprising:a) adding a macroporous magnetic ion-exchange resin having cationic functional groups to water containing humic and fulvic acids while imparting sufficient shear on the water to disperse said resin in the water, thereby facilitating adsorption of the humic and fulvic acids onto said resin; b) transferring dispersion from step a) to a settling region, thereby causing resin in the transferred dispersion to agglomerate and settle; c) separating agglomerated resin containing humic and fulvic acids adsorbed thereon from the water; d) disinfecting water from which humic and fulvic acids are removed; e) regenerating a portion of said agglomerated resin using brine, with the remainder being returned back to step a), thereby allowing continuous production of potable water; f) returning regenerated agglomerated resin to step a).
