Description
Summary:Yeast is a single-celled organism that is classified as a member of the fungi kingdom. Yeast has a significant role in the biological treatment of wastewater. The bio-sorption technology is applied to remove many pollutants such as heavy metal, dyes, and organic materials such as phenol. This technology is characterized by being inexpensive and environment-friendly. This research reviews yeast’s effectiveness as an adsorbent in removing heavy metals, dyes, and phenol from wastewater. The effects of some factors such as the concentration of pollutants, pH of the solution, and yeast mass in the bio-sorption process are reviewed. The bio-sorption process at equilibrium can be described using the isotherm model such as Langmuir and Freundlich isotherm models reviewed in this paper.
