Introduction
My research interests using of all optical devices and spectroscopy instruments in order to measure the quality before and after treatment of water and wastewater using different eco- friendly and law cost environmental materials including biological, chemical, physical and mathematical modeling. My recent researches cover the use of Microbial Fuel Cell (MFC) for both electricity production and wastewater treatment. I am also interested with preparing and teaching course materials.

Article
Industrial-scale testing was performed for fine screen reject recovery technology with a mixed office waste (MOW) pulping line. Results showed that the recovery system removed macrostickies and dirt specks with an efficiency of 95.7% to 98.3% and 51.5% to 76.8%, respectively. These results were not affected by the running consistency (0.26% to 1.44...
