Drinking water treatment with Caspian region natural sorbents

摘要

The objectives of the research of the microbiological composition were river water samples from the basic water-supply sources in Astrakhan region. The objects of the research of the water purification efficiency were the household filter that is widely-spread in a market and the handmade experimental filter with natural sorbents. The work employed the techniques to define total microbial count in the drinking water samples under study, and method of membrane filters to detect microbial cells of a certain size (Enterobacteriaceae) using filter pores of suitable dimension. Application of natural sorbents on the basis of further integrated study is perspective for production of water-purification filters that are available to the public, as coquina is quarried in the region and is effective for drinking water disinfection in comparison with usual household filters.
