A group of scientists from Istanbul Technical University (ITU) announced a technical evaluation report that includes the findings and possible solutions for the mucilage (sea saliva) problem threatening the Marmara Sea.

ITU faculty member Prof. Dr. Ismail Koyuncu, Prof. Dr. Izzet Ozturk, Prof. Dr. Mustafa Yanalak, Prof. Dr. Ozcan Arslan, Assoc. Dr. Ebru Dülekgürgen, Assoc. Dr. Mustafa Evren Erşahin and Dr. Instructor Member Türker Türken's opinions and suggestions regarding the mucilage problem are included.

The report, which includes analysis models of mucilage formation and the damages it causes, also includes satellite images provided by ITU Satellite Communication and Remote Sensing Center (UHUZAM).

White paper lays out the causes of the mucilage problem

According to the current data, 53% of the municipal wastewater in the Marmara Sea basin is mechanically treated, 42% is advanced biological (with C, N, P removal) treatment, and 5% is after biological (C, partial N, P removal) treatment. is discharged.

According to the results of the modeling studies carried out in the Marmara Sea and the Bosphorus, eutrophication control in Marmara and prevention of further deterioration of the dissolved oxygen level in the substrate; in other words, it is recommended to apply biological C, N and P removal treatment before all point wastewater discharges to Marmara, especially Istanbul, in order to ensure that the receiving environment is used for purposes such as swimming, water sports and fishing.

In the last 10 years, before the urban and industrial wastewater discharges to Marmara, especially Istanbul, Izmit and Bursa, biological N and P removal treatment applications have accelerated. kazanis gone. As a result of these practices, significant water quality improvements have been achieved and biodiversity has increased, especially in the Golden Horn, Izmit and Gemlik Bays. KadıköyIt is observed that the dissolved oxygen levels in the lower layer are < 2 mg/L in the eastern region of the Izmit Bay, where water exchange is limited with the Büyükçekmece Baba Cape ~ northern Tuzla Peninsula axis, where the effluent of Küçükçekmece and Büyükçekmece Pre-Treatment Plants are discharged.

Suggestions for solutions to the problem of mucilage in 10 articles

1. The Marmara Basin, which includes the Sea of ​​Marmara, the Straits and its sea connections, should be considered and evaluated as a whole.

2. An interdisciplinary scientific-based approach should be applied and university-public-industry-private sector-NGO collaborations should be developed in order to reduce the pollutant loads that increase mucilage formation processes in the Sea of ​​Marmara.

3. The maximum amount of Advanced Biological WWTP effluent should be used in the irrigation of urban green areas (if any) and/or in industry, to reduce the amount of wastewater given to Marmara.

4. Recycling in wastewater treatment plants kazanshould be given priority. In this context, the implementation of innovative, space-saving and energy efficient wastewater treatment processes should be initiated.

5. The OIZ and individual industrial facilities should be prevented from discharging priority and hazardous materials into the municipal canal network through effective monitoring and inspections.

6. The formation of ecological conditions in the upper layer of the Marmara Sea should be supported. With the migration of fish between the Black Sea, Marmara and Aegean Seas, fish shelter/spawning areas should be protected and the sustainability of these regions should be ensured.

7. Water quality should be constantly monitored, monitoring, inspection and sanction capacities of domestic and industrial WWTP discharges should be developed, and deterrent sanctions should be imposed on facilities that are not operated in accordance with standards, and monitoring data should be shared.

8. The operation of advanced biological wastewater treatment plants by specialized private sector companies based on contracts of at least 8-10 years should be expanded.

9. Satellite images with different spatial and temporal resolutions should be provided, especially for monitoring mucilage and contamination. Active satellite systems should be examined and integrated into studies.

10. A dynamic Geographic Information System (GIS) that will also serve as a decision support system for the Marmara Sea and Basin should be established. Up-to-date information about the Marmara Sea and the areas it interacts with should be produced continuously, the structuring and changes in these areas should be determined, and the effects on the Marmara Sea ecosystem should be revealed.
