\MICROWAVE SUPPORTED TREATMENT OF SEWAGE SLUDGE

František Janíček – Milan Perný – Vladimír Šaly – Markus Giemza – Peter Hofmann

   This work is focused on microwave treatment of sewage sludge. The aim of our experiments was to investigate the impact of microwave radiation upon different sewage sludge parameters such as concentration of nitrates and nitrites, phosphates, COD (Chemical Oxygen Demand), SVI (Sludge Volume Index) and the microscopic structure of sludge. The experiments with microwave irradiation of sewage sludge indicate that moderate microwave power causes visible effects on the chemical, physical and biological properties of the sludge. The calculation of profitability and energy efficiency is also presented.

Keywords: gasification, microwave radiation, microwave reactors, waste
