SORPTION DRINKING WATER TREATMENT METHOD Russian patent published in 2008 - IPC C02F9/08 C02F1/28 C02F103/04 

FIELD: chemistry.

SUBSTANCE: method involves preliminary cleaning of water using pulp from powdered clinoptilolite-montmorillonite ore and activated carbons with continuous supply of the pulp to the cleaning system. At the first stage the water is more than 50% pure and goes through the basic cleaning stage by coagulation, elutriation and filtration. Filtration is carried out by three filters: with filtering material - granodiorite in the first two filters and clinoptilolite in the third filter. At the finishing purification stage, the water undergoes extra filtration through filter cassettes with filtering material made from clinoptilolite with its subsequent decontamination using ultraviolet beams.

EFFECT: improvement of the quality of water with lower concentration of harmful substances with lower cost price of purification.
