Anaerobic digestion is a process in which microorganisms break down biodegradable substrates in the
absence of oxygen. It can be used to treat various organic wastes and recover bio-energy in the form of
biogas, which ...
The majority of the antimicrobial compounds used for treating textiles are synthetic based and are not considered to be environmentally friend. Therefore, solanum incanum fruit and onion peel were selected for the current ...
In this study, the adsorption efficiency of Ethiopian sodium bentonite clay adsorbent for removal of Cr (III) and Cr (VI) ions from tannery effluents has been investigated. The clay was found from Gewane area, Afar region, ...
The growth in various types of industries together with population growth has resulted in enormous
