Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2017)Transition metal and metalloid oxyanions such as Cr-compound (CrO4-2) and As-compound (H3AsO3) are common pollutants routinely detected in effluent waste streams from the mining industry around the world. Biological treatment ...

Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)Catalytic bio-oxidation of toxic Arsenite (As(III)) to Arsenate (As(V)) in a mixed culture of bacteria strains isolated from cow dip in Tzaneen (Limpopo Province South Africa) was investigated under anaerobic condition. ...

Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)Ceramic bead media Biofilm Reactor Performance was evaluated for Cr(VI) reduction utilizing As(III) as electron source with mixed culture of chemoautotrophic bacteria. The inoculant used was isolated from cow dip in Tzaneen ...

Igboamalu, Tony Ebuka; Nyakale, Atlegang; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (Italian Association of Chemical Engineering, 2020)Biocatalytic oxidation of Arsenite (As3+) to arsenate (As5+) in a mobilized and immobilized chemoautotrophic bacterium has been a challenging area of metallic bioremediation research. This is because arsenic in its trivalent ...

Igboamalu, Tony Ebuka; Needham-Clark, Benjamin; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)The energy output of a dual chamber anoxic microbial fuel cell (MFC) subjected to variation in the substrate concentration was investigated. Wastewater from a primary clarifier effluent stream was used as the MFC inoculum. ...

Igboamalu, Tony Ebuka; Bezuidenhout, Neil; Matsena, Mpumelelo Thomas; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2019)The primary objective of all microbial fuel cell (MFC) research is currently to find ways to increase its efficiency by optimising design architecture and operating values. Microbial fuel cells (MFCs) are however very ...

Matsena, Mpumelelo Thomas; Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)Hexavalent chromium [Cr(VI)] which are discharged together with organic pollutants in effluent streams from industry pose a health hazard to humans. The present study observed the reduction of Cr(VI) in presence of phenol ...
