By-products of disinfection of potable water at placing of armies in field conditions

Abstract

On the basis of studying of the data published in open sources, the problem of the comparative characteristic of potential danger of various methods of disinfection of water about formation in process or as a result of its clearing of the substances possessing toxic and (or) cancerogenic action dared. Application of practically all methods, both traditional, and perspective is established, that is accompanied by formation of by-products of disinfection directly in potable water or as a part of drains in the form garbage removed from the water. Now the most widespread, effective and economic way of disinfection water is the use of chlorine-containing preparations. Such approach provides destruction of the majority of pathogenic microorganisms that defines the application of chlorine-containing preparations in world practice of clearing and water disinfecting in spite of the fact that at their use there is a formation of the big number of products of collateral disinfection. As concentration of the last depends on parameters of the process of disinfection, to solve a safety problem it is offered by strict observance of conditions of technological process, instead of prohibition of application of those or other techniques. The most perspective for water preparation perfection in the field conditions, having the least quantity of by-products of disinfection, is the approach to disinfecting of water which includes two alternative systems: reverse osmosis and an ultrafiltration (and in the long term nanofiltration) with possibility of a choice of one of these variants of clearing. As concentration of the last depends on parameters of the process of clearing, to solve a safety problem it is offered by strict observance of conditions of technological process, instead of prohibition of application of those or other techniques. The basis for refusal of connection of field camp to the centralised networks of water supply and use of the chlorinated potable water is not revealed.
