Key words: biosorbent, immobilization, hydrocarbon, hydrocarbon oxidizing microorganisms, carbon-containing waste.
New method of biosorbent obtaining is proposed. Hydrocarbon obtained as a result of surplus active sludge modification was used as a matrix. Physical characteristics of hydrocarbon are not correspond to natural carbon sorbents, but are sufficient for using as a matrix for microorganisms immobilization on the porous surface. Results of investigations are considered to be the base for justification of technological process parameters for biosorbents obtaining on the base of carbon-containing waste and technology of biosorbents production. Proposed method of biosorbents obtaining allow to use material potential of carbon-containing waste, to reduce volumes of landfilled waste, to use efficiently obtained biosorbents in environmental technologies in processes of water and wastewater treatment from petroleum products, and bioremediation of oil contaminated soils.
