Membrane Installation Development for Post-Treatment and Сonditioning of Drinking Tap Water according to the World Health Organization Standards
Vladimir A. Lazarev, Elena G. Miroshnikova
Authors introduced and tested the layout of reverse-osmosis production plant for final purification of cold tap water with a capacity of 10 l/h with the possibility of changing the purified water mineral composition. The development relevance is due to both global anthropogenic pollution of the biosphere and the deterioration of urban water supply networks. Authors developed a multi-stage membrane system using modern methods of water treatment to remove mechanical, chemical and microbiological contamination from the water. At the final stage, a man improved the quality and organoleptic properties of the purified water using the “post-filter mineralizer” production plant. Research confirmed the equipment stability and the characteristics compliance of the resulting product with both the requirements of Russian regulations and the norms of the World Health Organization experimentally during the one-year operation cycle. Authors scrutinized water quality and safety indicators on the basis of SanPiN 126.96.36.1994-01 “Drinking water. Hygienic Requirements for Water Quality of Centralized Drinking Water Supply Systems. Quality Control». Measurements of the total water salinity showed that it decreased from 200 ± 20 mg/l in the source water to 22 ± 2 mg/l in purified and conditioned water (at the recommended rate of not more than 50 mg/l).
