METHOD OF OBTAINING A COAGULANT PRODUCT, PRODUCT INTENDED FOR MANUFACTURING THE SAID COAGULANT, AND METHOD OF TREATING WASTEWATER AND/OR INDUSTRIAL EFFLUENT USING THE SAID COAGULANT.

摘要

The invention relates to a method of obtaining a coagulant product. Characteristically, a raw material is prepared which contains the sludge resulting from the treatment of drinking water and an ore containing iron and/or aluminium, this raw material being subjected to acid attack for the purpose of forming iron salts, aluminium salts or a mixture thereof. This coagulant is employed in the realization of a physicochemical step in the treatment of wastewater and/or industrial effluent.
