Annotation:
There have been considered the problems of wastewater purification from oil products and solids, for which FeCl3 and Ca(OH)2 were used as a coagulant. It has been shown that at a concentration of 1,0 gr of Ca(OH)2 plus 0,06 ml of FeCl3 solution, the water is completely purified from impurities and becomes transparent, its colour, turbidity and odour disappear completely. A model of the kinetics of wastewater purification process in the presence of the synergistic mixture is suggested. The spatial interpretation of the wastewater purification process is given, proving the fact that the purification degree decreases with the increasing quantity of synergistic mixture and tends to a small constant value.
