METHOD OF PREVENTION OF IRON OXIDES OCCURRENCE IN ARTESIAN WELLS ENCASED BY METAL PIPES WITH HELP OF SEALED HEAD WALL

摘要

FIELD: process engineering.SUBSTANCE: invention relates to water supply and can be used in outfitting of artesian wells with hydraulic accumulators and concrete water storage tanks. Besides, it can be used at artesian wells with sealed water towers and metal tanks. Method of prevention of the occurrence of ferrous and ferric iron oxides in artesian well water consists in fitting the sealed head wall to seal the casing against the air oxygen ingress therein. Besides, the cable and water lift pipe are sealed at the sealed head wall inlet.EFFECT: decreased content of total iron in walls encased by metal pipes to less than 0,3 mg/l to comply with the requirements of the State Standard GOST "Drinking Water".
