Hydrogen Production Via the Electrolysis of Municipal Effluent Using Carbon Fibre and Nickel-Foam Anode

This study aims to explore hydrogen production via alkaline water electrolysis using municipal effluent. The experiments were conducted in a flow cell electrolyzer using carbon fibre and Ni-foam as the anode, with another Ni-foam electrode employed as the cathode for all experiments. Synthetically prepared effluent and real municipal effluent...

Water purification in a solar reactor incorporating TiO₂ coated mesh structures

The rate of photocatalytic oxidation of contaminants in drinking water using an immobilized catalyst can be increased by properly designing the catalyst structure. By creating a solar reactor in which meshes coated with TiO₂ were stacked, we demonstrated that degradation of humic acids with four superimposed stainless steel meshes...

Fungal removal of humic acids from treated wastewater: Potentials for a continuous flow non-sterile bioreactor

In order to address the ambiguities and knowledge gaps in the HA removal by WRF, mechanisms of removal were explored in chapter 2. It was shown that the mechanisms of HA removal by WRF involves the degradation of HA to smaller molecules, conversion to FA and also biosorption of HA by fungal mycelia. Furthermore, the ability of laccase to...

Fungal treatment of humic-rich industrial wastewater: application of white rot fungi in remediation of food-processing wastewater

This paper presents the results of fungal treatment of a real industrial wastewater (WW), providing insight into the main mechanisms involved and clarifying some ambiguities and uncertainties in the previous reports. In this regard, the mycoremediation potentials of four strains of white rot fungi (WRF): Phanerochaete chrysosporium, Trametes...

Bioremoval of humic acid from water by white rot fungi: exploring the removal mechanisms

Mitigation of Humic Acid Inhibition in Anaerobic Digestion of Cellulose by Addition of Various Salts

Humic compounds are inhibitory to the anaerobic hydrolysis of cellulosic biomass. In this study, the impact of salt addition to mitigate the inhibitory effects of humic compounds was investigated. The experiment was conducted using batch tests to monitor the anaerobic hydrolysis of cellulose in the presence of humic acid. Sodium, potassium,...
