    Constructed and riverine wetlands design considerations for domestic and agricultural diffuse pollution treatment-a case study from Turkey
    (TAYLOR & FRANCIS INC, 2016) Gunes, Kemal; Tuncsiper, Bilal; Drizo, Aleksandra; Masi, Fabio; Ayaz, Selma; Tufekci, Huseyin
    In this study, a riverine constructed wetland system (RCWS) was monitored with the aim to investigate its functionality and cost-effectiveness in treating domestic wastewater. Turkey's second biggest freshwater lake, Eirdir lake, is becoming polluted directly and indirectly with both domestic and diffuse pollution sources. In this paper we: (1) describe a water quality monitoring campaign on an existing long drainage channel where the majority of pollution originates from untreated urban sewage (2) discuss the design parameters and some considerations for a new RCWS to diminish and eliminate domestic and diffuse pollution loads originating from Gelendost and Yaka. In our design considerations, (1) we projected population increase over a 30-year period, which resulted in total 12,000 population equivalent, including the drainage network run-off originating from agriculture; (2) we aim to achieve 90% reduction in chemical oxygen demand, 70% of nitrogen (N) and 40% of total phosphorus. To achieve design objectives, we propose that the new RCWS consists of six horizontal flow CW and seven FWS systems, laid out within the drainage channel bed itself. This project would represent one of the few systems specifically designed to provide diffuse pollution treatment, and would be the first system of this kind in Turkey.

    Domestic wastewater and surface runoff treatment implementations by constructed wetlands for Turkey: 25 years of experience
    (Elsevier, 2021) Gunes, Kemal; Masi, Fabio; Ayaz, Selma; Tuncsiper, Bilal; Besiktas, Mehmet
    The first studies on constructed wetland (CW) system in Turkey applied at the TUBITAK Marmara Research Center (TUBITAK MRC) in 1994. These studies carried out both in laboratory and pilot applications within TUBITAK MRC campus. Treatment performances were investigated by using different types of wetland plants in different types of wetland systems. After 2000, the real scale CW treatment systems where implemented in various regions of Turkey. Submerged horizontal flow systems (SFS-h or HF), free water surface flow (FWS) and various hybrid systems were applied in the Egirdir Lake basin. In order to treat both domestic wastewater and runoffs from agriculture, real scale CW systems designed in the Egirdir lake basin. Apart from these, the CW systems were built for the treatment of the domestic wastewater of 5000 people equivalent in the Konya closed river basin. Furthermore, pilot scale systems were carried out by using different types of wetland systems for the treatment of runoff from highways and railways in Sapanca lake basin. All of the treatment system has provided treatment criteria set forth in the regulations in Turkey. The biggest problems encountered in these systems are related to the operation and maintenance. Some systems have been inactivated because of not enough personnel have been allocated. In this study, applied research projects conducted in Turkey on CWs for 25 years were evaluated and relevant problems encountered presented.
