Abstract
A process for clean-up of pollutant ladent water of the type characteristically produced in conventional container manufacturing installations. Such waste water is derived typically from water based printing ink wash-up and/or starch adhesive wastes. The process produces highly purified, optionally colorless water adapted for re-use and/or discharge. The process employs chemical treatment of such a starting aqueous waste to facilitate removals of colloidal particles and heavy metals followed by physical removal of suspended solids. Optionally, the resulting treated water is further subjected to decolorization.
