Abstract

Otpad kao posljedica ljudske djelatnosti predstavlja glavni problem vodoopskrbe i odvodnje. Osnovni problem stoji u činjenici da otpadne tvari zagađuju okoliš. Jedno od najizazovnijih pitanja u upravljanju otpadnim vodama je gospodarenje muljem koji se generira na uređajima za pročišćavanje otpadnih voda. Prosječna proizvodnja otpadnog mulja kreće se od 20 do 32,85 t po osobi godišnje. Ove ogromne količine mulja stvaraju velike probleme u gospodarenju otpada općenito. Obrada i zbrinjavanje mulja je sastavni dio pročišćavanja otpadnih voda. Iz tog razloga, razvoj rješenja za pročišćavanje otpadnih voda mora uključivati rješenje za obradu i zbrinjavanje nastalog mulja, a troškovi obrade i zbrinjavanja mulja su inherentni trošak pročišćavanja otpadnih voda. Navedeni problem uzrokovao je potrebu za pronalaskom kvalitetnijih rješenja, tako je i jedno od tih rješenja mikrovalno sušenje mulja o kojem će se detaljnije govoriti u ovom radu.

Abstract (english)

Waste as a consequence of human activity is the main problem of water supply and sewerage. The basic problem lies in the fact that waste pollute the environment. One of the most challenging issues in wastewater management is the management of sludge generated at WWTPs. The average production of sludge ranges from 20 to 32.85 t per person per year. These huge amounts of sludge create major problems in waste management in general. Sludge treatment and disposal is an integral part of wastewater treatment. For this reason, the realization of a whole wastewater treatment project must include a solution for the treatment and disposal of the resulting sludge, and the costs of treatment and disposal of sludge are an inherent cost of wastewater treatment. This problem has caused the need to find better solutions, so one of these solutions is microwave drying of sludge, which will be discussed in more detail in this paper.
