Aerobic Bio-oxidation with Ozonation for Recalcitrant Wastewater Treatment
Journal of Advanced Oxidation Technologies, 2008AbstractThe aim of the present research was to find a combination of biological and chemical oxidation processes that improves the purification efficiency of recalcitrant wastewater treatment at reduced ozone consumption. The following wastewater treatment processes were experimentally studied: conventional aerobic biooxidation, post-ozonation of ...

Procedure for determination of elemental sulphur bio-oxidation rate
Bioprocess Engineering, 1989A procedure is described for measuring the rate of biooxidation of elemental sulphur in nutrient solutions. Results of preliminary measurements of sulphur bio-oxidation rate in a dynamic system are presented. The rate of sulphur bio-oxidation has been determined at the level of 0.02–0.05 g of sulphur per m2 of sulphur per h.

Bio-oxidation of minerals in air-lift loop bioreactors
International Journal of Mineral Processing, 2001Abstract The high rate bio-oxidation of minerals in tanks has received a great deal of interest over the last decades. So far, aerated stirred tank reactors, which are common in the mining industry, have been used for these processes. However, as we are dealing with a biological system, it makes sense to apply reactor types that are especially ...

Surface Characteristic of Pyrrhotite Bio-Oxidized by Acidithiobacillus Ferrooxidans
Advanced Materials Research, 2011This paper deals with the surface characteristic of pyrrhotite bio-oxidized byAcidithiobacillus ferrooxidans. Large amounts of jarosite and element sulfur were determined in the bio-oxidation processe of pyrrhotite. More complicatedly, biofilm exists on the surface of pyrrhotite. This type of structured community ofA.

Bio-Oxidation Operation Parameters of Handling Optimization Outer Mining
2012China is a extensive resources country, but years of continuous exploitation make resources exhausted, the easy treated goldmine just like them. According to the study, the relativity domestic refractory gold resources is about 1,000 - 1,200 tons (about 1/3 of the proven reserves), which is mainly distributed in the southwest, northwest and northeast ...
