Summary

The biotechnology of sewage water purification from phthalic ethers is based on the use of micro organisms-decomposers of phthalates. High level of efficiency of sewage purification from phthalic ethers is ensured by fixing of micro organisms-decomposers on fine-fibrous carrier. Biotechnology is environmentally friendly, non-waste and cost effective.

Description

The biotechnology is based on micro organisms-decomposers using phthalic ethers as the only source of carbon and energy. High level of efficiency of sewage purification from phthalic ethers is ensured by fixing of micro organisms-decomposers of Rhodococcus type on fine-fibrous carrier in series-connected blocks of anaerobic and aerobic bioreactors.
Sewage water treatment with the help of micro organisms-decomposers ensures a high level of utilization of effluent components that are decomposed to carbon dioxide and water. In the process of water purification intermediate toxic metabolites are not stored; thus the process of decomposition appears to be completely harmless. No wastes that have to be disposed or thermo decontaminated are produced as the rest of biomass is transferred with purified water from bioreactor to biological treatment facilities where it forms sewage sludge being a harmless organic component.
