Sabreen Daghera, A student of the Environmental Studies Program / Faculty of Science and Technology at Al-Quds University, discussed a master's thesis titled: "
“Improvement of large scale wastewater treatment plant using Epuvalisation technique and micelle clay complex column”
The thesis focused on the improvement of the sewage treatment plant at Al-Quds University using two techniques, one using an epuvalisation technique and another one using a micelle clay complex column. Where the results showed in the first technique the possibility of using it to treat secondary wastewater and purification through the irrigation of ornamental plants rosemary, and the plant hibiscus. The results showed that by comparing water quality analyzes between irrigation with treated wastewater and secondary freshwater, there was a decrease in the biological demand of oxygen (BOD) and chemical oxygen demand (COD). Moreover, the results of growth rate parameters and chemical analysis of plants (roots, stems and leaves) showed that there is no difference between plants that are irrigated by both types of irrigation water. And there’s no presence of high concentration of salts in any of the sections of plants.
The results of the second technique by adding the micelle clay complex column within the wastewater treatment plant showed that it contributed in reducing the fouling in the filtration provided. Therefore, we can also save one of the advanced filtration steps that cause the station's operational cost to rise, which is UF-SW. This treatment can be considered a proactive step for advanced filtration using reverse osmosis so that UF-SW can be dispensed with.
Sabreen participated in three local conferences in three Palestinian universities for this study and an international conference in Muscat, Oman.
At the end of the discussion, the committee that was composed of the main supervisor of the letter, Dr. Muhannad Qurei, the internal examiner Dr. Amer Kanaan, and Dr. Zaher Al-Barghouthi the Deputy Director General of the Palestinian National Center for Agricultural Research, granted the student a master's degree successfully.
