Development of a burner to measure biogas generation
(2012-09-10)
This paper describes the development of a system of an automated biogas burner which records the amount of biogas burnt by a biogas low flow system. The biogas produced in mini SST biodigestors, (mini station of sewage ...

Bioleaching of toxic metals from sewage sludge by co-inoculation of Acidithiobacillus and the biosurfactant-producing yeast Meyerozyma guilliermondii
(2018-04-01)
The aim of this research is to evaluate the influence of co-inoculation of Acidithiobacillus bacteria and the biosurfactant-producing yeast Meyerozyma guilliermondii in bioleaching processes. The tests were carried out ...

Metal fractionation in sludge from sewage UASB treatment
(2017-05-15)
This study evaluates the trace metal composition and fractionation in sludge samples from anaerobic sewage treatment plants from six cities in Brazil. Ten metals were evaluated: Ni, Mn, Se, Co, Fe, Zn, K, Cu, Pb and Cr. ...
Heavy metals: The main factor limiting the agricultural use of sewage sludge
(2017-01-01)
Heavy metals occur naturally in rocks and soils being natural constituents of the Earth's crust that are rarely toxic. The excess heavy metals in soil originate from other sources, which include sewage improper stacking ...
