Abstract

The possibility of intensifying the purification of highly colored waters by aluminum hydroxychloride through optimization of coagulant-fluid mixing is confirmed theoretically and experimentally. It is proved that hydrodynamic conditions influence the purification efficiency in the pH range from 7 to 7.5. The advantage of hydraulic-type disperser over mechanical mixers is demonstrated. The value of energy dissipation is substantiated as a criterion of estimating the mixing intensity.
