Improvement of Adsorption-Ion-Exchange Processes for Waste and Mine Water Purification

The increase of ecological safety level of the hydrosphere as a result of the improvement of the adsorption processes for waste and mine water purification by using natural sorbents and desalting processes via electrodialysis has been investigated. The optimal parameters of improved sorption processes with natural sorbents have been established. The mechanism of diffusion was studied by the “kinetic memory” method. Effective coefficients of pore diffusion were determined during sorption of pollutants by natural sorbents.

Methods of salt content stabilization in circulating water supply systems

The effect of corrosion inhibitors and microbiocides presented in circulating water supply systems on the corrosion rate of structural materials has been studied. It is shown that using the mixture of zinc phosphonates aqueous solutions, special polymeric dispersants and microbicides based on bromine and quaternary ammonium salts provides dissolution of calcium carbonate deposits and the corrosion rate of steel materials at the lowest level. Rational modes of circulating water chemical treatment are proposed, which increase operational reliability.
