Kovalyov O. Biotechnological methods for heavy-metal ions and other contaminants removal using dry magnetic particles labeled biosorbent with Sacharomyces cerevisiae

The thesis addresses the problems of current interest. In particular, it aims to determine the optimal biotechnological parameters of wastewater purification with the use of dry magnetic particles labeled biosorbent (MPLB) with Saccharomyces cerevisiae yeast using a newly developed method of biosorbent magnetic particles labeling, which ensures homogeneity and stability of magnetic susceptibility, MPLB non-clasterization, and reduction of sorption duration through the use of the high-gradient magnetic separation, i.e. speed-range MPLB removal and maximizing the level of heavy-metal ions and other contaminants removal from wastewater. Еffectiveness of the dry magnetic particles labeled biosorbent is based on the fact that it does not cluster, has high sorption capacity, sorption effectiveness for Cu2+ ions is 93-95%. It also reduces the concentrations of wastewater pollutants (chemical oxygen demand, ammonium nitrogen, nitrites, phosphates, total iron) to the level of maximum permissible discharge. The results of this research can be used for dry biosorbent dose-ranging necessary for purification of wastewater in sewage treatment plants with complicated regulation of above mentioned factors.
