This article describes one of the modern technologies for processing and reduction of sewage sludge. Sludge in wastewater treatment plants (raw and excess activated sludge, etc.) should be treated, providing opportunity to its disposal or storage and to minimize its impact on the environment. The proposed method of reducing the sediment, namely activated sludge (which provides a decrease of 40-80%) can be embedded directly into the technology of sewage treatment, rather than in processing precipitation, which is very important and promising process.

Key words surplus sludge, treated waste water, ozonizer,disinfection,concentration, toxic substances, microorganisms.
