It tells to the use of the cavitation hydrodynamics as alternative for the water disinfection for the human supplying, extending it offers of water that takes care of to the fresh standards. In the state of the Ceará, in view of the precarious conditions of sanitation, used water sources for supplying, are superficial and or underground, it has presented one raised contamination index. The water that is supplied the population must be exempt of the presence of pathogenic. disinfection consists in the measure of treatment that has as main goal the elimination of the .causing of illnesses, carried through by means of physical and/or chemical agents. The chlorine if has detached as the spread out deodorant more, however studies recently published bring that, many of these chemistries, can be harmful to the users of treated waters and the environment. E that some .causing of illnesses, are more resistant to the traditional deodorant chlorine of what the coliform bacteria of the group. With this, the necessity exists of if to develop disinfection processes you add that they could eliminate or reduce the use of these chemical disinfections. By means of a bibliographical survey of the engineering applied in the conception of the cavitation technology hydrodynamics, they had been constructed to archetypes for water production disinfected through the cavitation hydrodynamics; evaluating the potential of cavitation generation hydrodynamics through the presented thermal efficiency in the archetype; e the study of the quality bacteriological physicist-chemistry and of waters used in the experiment. The end of the test unit was possible death of the observed microorganism, gifts in the water of feeding of the reactor that had as feeding outflow the value of 60L/h and power of 30KW. Presenting itself as an alternative of disinfection, characterized for the possibility of adoption in plants personal of water supply or in communities of small which had mainly transport, not the by-product generation, mobility of the outflow of operation of the system and not the use of chemistries.
