[Hygienic evaluation of the methods of water conditioning on marine ships].

Results of test stands and of field studies (on marine ships) have shown, that the use of installations for water preparation (IWP), including mineralizers of the wash out type and ozonizers, makes it possible to get water of stable quality independent of the terms of operations of the installations, and also provides the possibility of conditioning of shore water supply and of carrying out disinfection of the ship water supply system. Comparative analysis of the operation of various kinds of IWP on marine ships testifies to the necessity of development of the new types of IWP, which will promote health preservation of crew members having difficult long independent voyages.
