The use of electrolysis in the creation of waste-free water purification processes

Methods of water pre-treatment before baromembrane installations in order to remove the predominant amount of salts are proposed. The technological scheme of obtaining high-quality permiate in the amount of 90-95% of the initial volume of water during its preliminary stabilization treatment has been developed. The influence of various factors on the quality and yield of permiate has been established.

Protection of surface water bodies against pollution by nutrients and heavy metal ions

New methods have been developed for sample preparation and analysis of heavy metal ions in water based on polarography, which provide an accuracy of 2-6 orders of magnitude higher than those known today. Methods for determining trace concentrations of heavy metal ions in water have been developed. New processes of separation and removal of ions of heavy metals, chromates and other anions from acidic and alkaline solutions have been studied and developed to produce metals and chemical reagents suitable for reuse.

Resource-safe synthesis technology and finish treatment of high-temperature bearing materials on the basis of tool manufactures wastes.

There were processed new methods of using valuable secondary resources – grinding wastes of tool manufactures – steels Р6М5, Р6М5К5, Р6М5Ф3 for manufacturing effective composite sliding bearings of high-temperature using. New resources-safe technologies of synthesis and finish grinding of bearing composite from new materials have been developed.
