Photocatalytic degradation of methylene blue dye and fungi Fusarium equiseti using titanium dioxide recovered from drinking water treatment sludge

Massive amount of water treatment sludge is produced annually and majorly being treated via landfills which will eventually lead to the environmental problem. In this study, an attempt was made to evaluate the photocatalytic activity of titanium dioxide (TiO2) that was extracted from drinking water...
