Krimets G. Coagulantion composition on the basis of Ukrainian kaolin

Dissertation is devoted development of technology of receipt of powder complex reagent for water treatment from Ukrainian kaolin of bad quality raw material. Certainly basic physical and mechanical descriptions of kaolin clays and recommendations are offered, that to the storage transporting and dosage of the last. It is set that the optimum method of processing of bad quality kaolin clays is sulfate acid caking for temperatures not higher 573K. Based on an understanding of the kinetics of the process was a rational synthesis time which was 60 minutes. The mechanism of flowing of process of sulfatizatstiya is offered and the basic kinetic parameters of process are expected. It is set that a process flows in two stages which are described equalizations : first stage - Kolomogorova Erofeeva, and second - Roginskogo. Establishment of mechanism of motion of process allowed to ground technological time of leadthrough of proces, which made 60 minutes. Industrial tests were carried out on experimental industrial plant for assembly Shostkinsky plant chemicals. In laboratory and industrial terms high efficiency of work is rotined got a standard in comparing to the existent analogues during cleaning of from different admixtures. Optimal doses of reagent for the purification of water from a variety of pollutants and a comparison with the existing reagent obtained. As an existent analogue used the cleared sulfate of aluminium comparison with the industrial design sample showed high more efficiently clean water from a variety of pollutants. During the experiments it was shown that treatment as a model and real water containing in its composition as a component to pollution that many. The optimal dose for the removal of most pollutants (except heavy metal ions) is a dose of 35 - 40 ppmAl2O3 (to remove heavy metal ions should be applied dose of 60 - 70 ppmAl2O3). The optimum pH range of the synthesized sample, which is 3 - 6 and 8 - 9. Shown and proven the existence flokulyatsiynyh properties of the synthesized reagent crude aluminum sulfate. Shown that the reagent has received some sorption properties and defined specific surface, which is 108 m2 / g and pore volume for benzene - 0.24 cm3 / g. An experimental-industrial tests of the synthesized reagent and proved its high efficiency in the process of electroplating wastewater treatment plants. E Production of crude aluminum sulfate coagulant for the technology is feasible and justified.The cost of one kilogram of coagulant is 10.46 grn / kg.Profits at the level of profitability of 18% will be 0.98 million / year, with production of 3,000 t / year proposed coagulant.The return on investment -5.83 years.
