An Effective Reagent for Perufication of Flow Waters

In this paper, we make the comparative analysis of efficiency of flow waters perufication by coagulants on the basis of aluminium sulfate - industrial standard (Al2(SO4)318H2O) as well as a novel coagulant, synthesized by our technology. The efficiency of coagulants action is tested on the models and real standards of flow waters in the processes of perufication from lees, dyes, some ions of heavy metals. We also set the limits of рН efficient work of the synthesized standard.

The study of non-isothermal kinetics of the process of kaolin sulphatization furnacing

This study considers the non-isothermal kinetics of kaolin sulphatization process with obtaining the crude aluminium sulphate as a main product. Using the methods of non-isothermal kinetics ensures obtaining the principal kinetic constants of the process in the temperature interval 50–235 °С within the scope of one experiment. Moreover, we demonstrate that the sulphatization process proceeds in several stages and we calculate the kinetic parameters for every single stage. Through experiments performed, we obtain the kinetic equation of the process speed.
