FIELD: treatment of water.

SUBSTANCE: invention relates to a method for purifying waste water, where waste water is electrochemically treated in the presence of an anolyte, wherein the anolyte is added as an additive where the anolyte is a form of electrolysed water containing ions and radicals H₂O, H⁺, H₃O⁺, O₂, OH^-, HOCl, ClO^-, HCl, Cl^-, HClO₃. The invention also relates to an application of the anolyte as an additive in the method for electrochemical purification of water to reduce the doses of coagulants and/or flocculants and to implement the method without the need for adjusting the pH.

EFFECT: use of the proposed invention provides a possibility of purifying waste water to a level where water is suitable for treatment by means of membrane filtration without using large amounts of chemical substances.
