Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: dissolution of commercial reagent takes place through multiple circulations of the contents of the tank through cavitation-vertical flow in which the dispersion of particles of the prepared suspension takes place right down to their nano-sizes with simultaneous increment of temperature, moreover more temporal value of circulation corresponds to higher heating temperature. Whereby the root mean square of the velocity gradient of mixing the suspension (G) is from 1000 c-1 and circulation time is from 4 to 15 minutes. ^ EFFECT: reduction of operational costs related to the heating of water for preparing a working solution during the period of low temperature, intensification of the process of aggregation of suspended substances by improving adsorptive substances of the suspension of aluminium poly-oxychloride and increasing the ageing time of the working solution of coagulant. ^ 5 ex, 2 tbl
