The present work is focused on developing effective and efficient mass consumer household filters to treat drinking water with natural sorbents which is especially important for developing regions communities. The aim of the research was to study modern methods and devices of drinking water purification and their efficiency in water disinfection, as well as utilization of local natural sorbents taking into account negative impact of climatic, epidemiologic and anthropogenic factors in the Caspian region environment. It was necessary to describe the existing modern methods of purification and disinfection of the water for drinking; to analyze the quality of water samples taken from different water-supply sources; to make a comparative microbiological quality analysis of the water, purified with household filters that are widely used and usually sold in shops and with handmade filters on the basis of the local natural sorbent - natural coquina. Application of natural coquina is perspective for production of water-purification filters that can be widely available, as coquina is quarried in the region and is effective for improvement of the microbiological parameters of drinking water quality as well as because of low costs of finished goods necessary for people both in urban and particularly poorly developed rural areas where water treatment is for various reasons not available.
