FIELD: technological process.
SUBSTANCE: invention is related to methods of sewage and natural water treatment from ions of sulfate bivalent iron and may be used in different industries, including mining, chemical and machine building industries. Method includes preliminary mixing of initial water with calcium carbonate and supply for aeration in the form of air-water pulp. Aeration is carried out with excessive pressure of 1-6 atmospheres for 0.5-5 minutes. After aeration treated water is directed for clarification with achievement of normalisation of pH to 6.5-7.5.
EFFECT: provides reduction of technology cost, reduction of volume of formed deposit and provision of treatment of sewage and natural water from ions of sulfate bivalent iron.
