Water Quality Improvement by Additional Filtering through Sorption Loading Modified by Fullerenes

Abstract

The actual problem of necessity of additional water processing for the consumer’s drinking purposes is considered. It is connected with water passing through the city pipes the condition of which is unsatisfactory, repeatedly become soiled by physical, chemical, and bacteriological components; it is also promoted by greater duration of stay of water in the water delivery system. The technique of modifying activated coals by fullerenes is presented. The technique of research of the initial and modified birch and coconut drawn up coals is developed by filtering. Permanganate demand, chromaticity, the content of ferrum in the initial and treated water is chosen as controllable parameters. Results of comparative laboratory researches of the initial and modified activated coal as a result of additional water processing are demonstrated. An original technique of regeneration of the used activated coals with application of sodium hypochlorite is developed. Bactericidal properties of the activated coal modified by fullerenes are confirmed. Dependences of duration of filter runs and efficiency of additional water treatment in filters with birch activated coal modified by fullerenes are obtained.
