Abstract:
A wastewater treatment process for treatment of an effluent from an industrial process for recovery or discharge of relatively pure water, comprising the steps of:controlling the pH of the effluent; contacting the effluent with a mixture of magnesium hydroxide and activated carbon to form insoluble magnesium salts and to absorb contaminated materials, the magnesium hydroxide and the activated carbon being admixed into a paste existing as a bed having surface area contact with the effluent; treating the effluent with a precipitating agent to form insoluble salts; treating the effluent with a flocculating agent to remove colloidal and finely divided solids; and, separating relatively pure water from precipitated materials and treatment materials to reclaim the water or discharge the water from the process.
