Abstract

Ovo istraživanje bazirano je na procjednoj vodi odlagališta komunalnog otpada i modificiranoj otpadnoj vodi. Voda je modificirana metodom standardnog dodatka slijedećih metala: Ba, Cu, Cd, Fe, Hg, Mn, Ni, Pb, Sn i Zn. Metali su uklonjeni iz modificirane otpadne vode metodom koprecipitacije sa željeznim hidroksidom i kalcijevim karbonatom te metodom adsorpcije na kaolinit, bentonit i kalcijev karbonat. Cilj istraživanja bio je objasniti i usporediti najčešće korištene metode za pročišćavanje otpadnih voda koristeći jeftine i široko dostupne materijale. Učinkovitost metoda utvrđena je nakon statističke analize prikupljenih podataka.

Abstract (english)

This research was based on leachate water from landfill of municipal waste and on modified wastewater. Water was modified by the Method of Standard Addition of the following metals: Ba, Cu, Cd, Fe, Hg, Mn, Ni, Pb, Sn and Zn. Metals have been removed from the modified wastewater by method of co-precipitation with iron(III) oxide-hydroxide and with calcium carbonate and by adsorption to kaolinite, bentonite and calcium carbonate. The goal of the research was to explain and compare mechanisms of the most common processes for purification of wastewater by using low cost materials. Effectiveness of the processes was determined after the statistical analysis of the gathered data.
