Abstract

The article deals with the formation of biofilms on plastic surfaces for wastewater treatment of small and medium enterprises for the processing of food products. Gives the composition of imitator of sewage and physico-chemical parameters of efficiency of bio-sorption purification. It is shown that after the end of the cleaning cycle the waste water, the observed values of monitored indicators were down 90,8—99,9 %. The results obtained were the basis for the evaluation of prevented environmental damage caused by water pollution. Performed microbiologic studies on the definition of microorganisms belonging to biofilm. We have identified protozoa (amoebae, ciliates and rhizopod), nitrifying bacteria (Nitrosomonas, Nitrobacter), zoogloeas, yeasts and molds. In a large number in the composition of biofilms are present kind by Pseudomonas bacteria.

Keywords

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