Current research activity

  • - physical and chemical bases of natural and waste water treatment with the help of coagulants, flocculants, sorbents (activated carbon, zeolites, etc.);
  • - study of the mechanisms and patterns of coagulation and flocculation processes;
  • - development of composite reagents for water treatment, synthesis of coagulants, increasing their coagulating ability.

Achievements

Composite reagents for natural and waste waters treatment have been developed, the use of which makes it possible to increase the coagulation aggregates sedimentation rate and the treatment degree relative to their aqueous counterparts (preliminarily dissolved or suspended reagents), simplify the treatment process, and also reduce the amount of coagulant introduced by 1.2–1.5 times (patent EA 036588).

A new coagulation-adsorption method for the treatment of multicomponent natural and waste waters has been developed, which makes it possible to remove pesticides with an efficiency of 99.6 –100 %, and at the same time reduce the content of various pollutants (surfactants, oil products, phenols, etc.) to the maximum permissible concentrations (patent EA 033558).

Recommendations for "Minskvodokanal" were developed to optimize the existing industrial technology of water treatment at the water treatment plant to remove substances that form unpleasant odors in the warm season, which made it possible to significantly increase the efficiency of removing substances that form the smell of water and reduce the content of residual aluminum in treated water.
