This paper presents a tool for the analysis of conversion of organic waste into energy. The tool is a program that uses waste characterization parameters and mass flow rates at each stage of the waste treatment process to predict the given products. The specific waste treatment process analysed in this paper is anaerobic digestion. The different waste treatment stages of the anaerobic digestion...

This review article addresses the use of biological activated carbon in water treatment and its techniques for development, with premise analyzing potential Activated Carbon (AC) human consumption. For this end, it aims to identify used production AC, benefits, from vegetable waste treatment. has ability selectively collect gases, liquids impurities inside pores, which is reason widely filtrati...

Inhibition of the respiration microbial activity in the activated sludge caused by heavy metal concentrations (Cr, Cd, Cu and Ni) was studied by means of respirometric method using Strathtox respirometer (Strathkelvin Glasgow).The studied sludge samples were obtained from the two waste water treatment plants with different types of pollution (municipal waste water and domestic waste water). Key...
