Article Citation - WoS: 3Citation - Scopus: 5Use of Geothermal Fluid for Agricultural Irrigation: Preliminary Studies in Balçova-Narlıdere Geothermal Field (turkey)(2021) Meriç, M. Kamil; Kukul, Yasemin Senem; Özçakal, Emrah; Barlas, N. Tuba; Çakıcı, Hakan; Jarma, Yakubu Abdullahi; Kabay, Nalan; Baba, AlperBalçova-Narlıdere Geothermal Field (BNGF) hosts the largest geothermal district heating system of Turkey and several geothermal wells used for district heating and thermal tourism activities. This study assesses the use of BNGF geothermal fluid for agricultural activities. The spent geothermal brine was treated using nanofiltration and reverse osmosis membranes on a pilot-scale membrane test system. The qualities of the product were evaluated in terms of agricultural irrigation integrated with the implemented innovative wireless sensor network. It is important to use geothermal fluid, which is consists of valuable minerals, for irrigation. But when using geothermal fluid in irrigation, the chemical composition of the water must be carefully monitored to prevent damage to the plants. Nevertheless, the first result shows that the use of geothermal fluid to irrigate is proving to be a promising and economically viable option in BNGF.Article Citation - WoS: 17Citation - Scopus: 19Effect of Operational Conditions on Separation of Lithium From Geothermal Water by ?-Mno2 Using Ion Exchange–membrane Filtration Hybrid Process(Taylor and Francis Ltd., 2018) Recepoğlu, Yaşar Kemal; Kabay, Nalan; Yoshizuka, Kazuharu; Nishihama, Syouhei; Yılmaz İpek, İdil; Arda, Müşerref; Yüksel, MithatA hybrid system coupling ion exchange and ultrafiltration (UF) was employed to separate lithium from lithium-spiked geothermal water. The effect of process parameters such as adsorbent type, adsorbent dosage, permeate flow rate, and replacement speeds of fresh and saturated adsorbents have been evaluated to determine the efficiency of the hybrid system. According to the results obtained using λ-MnO2 derived from spinel-type lithium manganese dioxide, the optimal operating conditions to separate lithium from geothermal water were found with powdery λ-MnO2 with an adsorbent concentration of 1.5 g adsorbent/L solution, replacement rates of fresh and saturated adsorbents of 6.0 mL/min, and a permeate flow rate of 5.0 mL/min. The ion exchange–UF hybrid system providing an advantage to work with very fine particles easily can be considered as a favorable process for the separation of lithium from geothermal water.
