Concentration Distribution of Molecules and Other Species in the Model System Fe-NaCl-Na2S-H2SO4-H2O at Various Temperatures of the Electrocoagulation Process

Zarlık MAYMEKOV | Canarbek İZAKOV | Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Mehmet KOBYA

Under practical conditions, one of the possible solutions to the problem of treatment of hydrogen-sulfide-containing industrial wastewater is the electrochemical oxidation of sulfides. In this work, the model system Fe-NaCl-Na2S-H2SO4-H2O is considered, an experimental setup is constructed, and the electrocoagulation process is studied in a wide (288-308 K) range of temperatures of an aqueous solution of hydrogen sulfide. The optimal ratios between the initial components in the system are determined. The experimental and calculated pH of the solution are found. The system is thermodynamically ...Более

The effect of various polymer-based coating types on the biological corrosion resistance of mortar

Tahir GÖNEN

As the urban population increases and the level of social life advances, the amount of wastewater originating from houses, institutions and industries increases as well. It is necessary for the infrastructure systems in settlements to be sustained under healthy conditions. Since the subsequent repair of infrastructure systems is difficult, appropriate selection of the materials used in these systems is of importance. Concrete pipes are widely used in sewerage systems. In the present study, it was aimed to improve the biological corrosion resistance of concrete pipes via coating with various ma ...Более

Exploring Landscape Archaeology and UAV-Based Survey in the Kochkor Valley, Kyrgyzstan

Kubatbek TABALDİYEV

From the earliest archaeological investigations along Central Asia's Tien Shan range, researchers have noted the diversity of highland communities and their participation in complex subsistence, exchange, and political systems. However, landscape archaeological approaches that might address socio-economic integrations have been limited by discontinuous, sometimes skewed datasets. Here, we present the results of UAV-based survey at Kok-Sai, an upland alluvial slope in the Kochkor Valley of north-central Kyrgyzstan, in which we identified more than 900 archaeological features in a 380 ha study a ...Более

Ammonia removal from wastewater by air stripping and recovery struvite and calcium sulphate precipitations from anesthetic gases manufacturing wastewater

Mehmet KOBYA

Anesthetic gas plant wastewater (AGPW) contains high concentrations of ammonia (NH3-N) and sulphate ions, which is known to results in severe environmental pollution in aquatic ecosystems without treatment. In the first stage of this study, a lab-scale investigation was done to improve removal of ammonia from AGPW by air stripping and struvite (or MAP: magnesium ammonium phosphate) precipitation processes, separately. The main operating parameters such as pH, air flow rate (L/min) and operating time were optimized for air stripping. The theoretical amount of removed ammonia via the air strippi ...Более
