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

Electrochemical Sulfur Removal at Controlled and Uncontrolled pHs with an Iron Anode

Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Zarlık MAYMEKOV | Mehmet KOBYA

In this study, sulfide removal was carried out in the Electrocoagulation process under controlled and uncontrolled pH conditions. Under optimum conditions, electrocoagulation took place in less than 40 minutes at uncontrolled pH and less than 30 minutes at controlled pH to reduce the sulfite concentration of the effluent below 0.5 mg/L. The reaction rate constant and iron-sulfide molar ratio for sulfide removal were 14.09 x 10(-2) min(-1) and 0.97 mol/mol, respectively; under uncontrolled pH conditions, they were 22.88 x 10(-2) and 0.97 mol/mol at controlled pH. The mg sulfide removed per g Fe ...Более

Removal of arsenic in groundwater from western Anatolia, Turkey using an electrocoagulation reactor with different types of iron anodes

Mehmet KOBYA | Mustafa DOLAZ

Electrocoagulation (EC) is a significantly efficient method for As removal from waters and received considerable attention recently. In this study, the natural groundwater (GW) samples containing As concentrations of GW-1: 538.8 mu g L-1, GW-2: 1132.1 mu g L-1, and GW-3: 52, 000 mu g L-1 were obtained from different provinces and treated by EC process using different iron anodes (plate, ball, and scrap). To achieve drinking water As standard (10 mu g L-1), the operational time, applied current, and As removal optimization for all anode types were studied. At applied current of 0.025 A, the As ...Более

Evaluation of textile wastewater treatment in sequential anaerobic moving bed bioreactor-aerobic membrane bioreactor

Mustafa DOLAZ

In this study, the treatability of real textile wastewater [dissolved organic carbon (DOC): 500 mg/L), color: 6383 Pt-Co, sulfate: 362 mg/L)] was investigated in sequential anaerobic moving bed bioreactor (AnMBBR) and aerobic membrane bioreactor (AeMBR). AnMBBR was filled with 40 % career material (Kaldnes K1). The effect of different hydraulic retention times (HRTs) (6-48 h) and powdered activated carbon (PAC) addition (1 g/L) was investigated for system optimization. Sequential AnMBBR- AeMBR was successfully operated for textile wastewater treatment corresponding to 92 %, and 90 % dissolved ...Более

RECOVERING OF INDIGO DYE FROM DENIM WASTEWATER WITH H2O2 IN THE PRESENCE OF KI CATALYST

Mustafa DOLAZ

Today, the textile industry, which is rapidly developing and growing in proportion to the human population, poses serious environmental and health problems in terms of waste. In the world, indigo dyes are widely used in the manufacturing of jeans fabrics especially in textile factories producing cotton fabrics. The overall objective of the present study is to recover indigo dye which is referred to as the pollutant released into the wastewater and to assess the removal of color via oxidation. For this purpose, denim wastewater containing solid particles and small size cotton fibers was filtere ...Более
