Abstract

Purification, based on a joint time and space bio-logical and adsorptive treatment of waste waters should be attributed to one of the most promising and versatile methods of biosorption. The article gives the analytical characteristic of bacterial adhesion and the processes of interaction between the bacterial cell surface and the substrate. The results of the studies on the purification of synthetic waste water with the help of an attached biocenosis and free of sludge forming in laboratory equipment are presented. The polymeric construction of the floating-type by the company “ETEK Ltd” with a width of cells from 10 to 15 mm were used as a carrier attached biocenosis. The article presents the data on the effect of temperature and hydrogen ion exponent (pH) in the adhesive activity of microorganisms and on the amount of removed nitrogen. It is shown, that the optimal process conditions for nitrification in laboratory equipment with the polymer structures of the floating type by the company “ETEK LTD” are temperature from 30 °C to 35 °C and pH from 8 to 9.

Keywords

biosorption, wastewater purification efficiency, preventing economic damage, economic instruments.
