Waste management

Possibilities of combined ways of treatment for selected waste types using an experimental equipment for physical waste treatment with the intention of their further use

This article presents possibilities of a unique device for industrial waste treatment using a patented process, and outlines possible future directions. This device, using different physical processes, individually or in synergy, e.g. combined effects of ultrasonic waves, focused microwave field, arc discharges, electrostatic field and the exposure to ultra-violet radiation, is intended to degrade dangerous substances in waste, reducing its hazardous properties for the environment and to prepare the waste for future applications (material or energy), i.e. separately or in combination with other technology processes, such as biotechnology.

Determination of selected illicit drugs in wastewater using liquid chromatography tandem mass spectrometry

The wastewater-based epidemiology approach to the analysis of illicit drugs was conceptualized in 2001 and for the first time was applied in 2005 for cocaine estimation in Italy. Further, other illicit drugs as heroine, cannabis and amphetamine have been estimated.

Quality of sludges and wastes from household and small wastewater treatment plants and their utilization in agriculture management

The aim of this article is to introduce partial sections of the research projects TA02020128 and TA02021032 (Technology Agency of the Czech Republic). These parts of the projects pay attention to the issue of quality of sludge and other wastes produced in wastewater treatment plants (WWTP) using activated sludge process, anaerobic processes (including septics) and extensive (natural) wastewater treatment plants (with horizontal subsurface flow reed-beds), which also include mechanical pre-treatment.
