“…In this sense, cost-effective process such as EC to recover them from wastewater and reuse in recent years has attracted the attention of researchers. In different studies, by applying various electrode materials as cathode and anode, high pollutant removal efficiencies were achieved.The electrocoagulation process performs very good treatments on aluminum and iron electrodes [20]. Comparison the results of this study with some studies is shown (see Table . 2).…”

“…While taking the time optimization values, 16 mA/cm 2 electricity was applied in the electrocoagulation device with the help of an aluminum metal electrode, and the study was carried out at the times determined for the time optimization study (10,20,30,40,50, 60, 90 minutes). The sedimentation process was ensured by keeping the wastewater passing through this process for 24 hours.…”

In this study, it is aimed to treat the wastewater from drilling operations during the creation of a natural gas storage area by electrocoagulation (EC) method. Boron and sulfate parameters in the wastewater were tried to be eliminated with the help of aluminum electrodes. During the removal of boron and sulfate pollutants, optimization studies were carried out on process time, pH, and current criteria. Boron (B) and sulfate (SO4) concentrations of wastewater generated during drilling were measured as 1.18 mg/L and 3348 mg/L, respectively. The samples taken after the purification work were placed in the measuring tapes and kept on hold for 24 hours. After the settling time, samples taken from the upper part were analyzed. During boron and sulfate removal, 16 mA/cm2 current, 30 min contact time, approximately 61% and 36% efficiency were obtained at 7 pH values.

Waste sludge disintegration and bound water reduction was investigated by comparative chemical oxidation using calcium hypochlorite, hydrogen peroxide, peroxymonusulfate and peroxydisulfate in the study. Response surface methodology (RSM) with Box-Benhken Design (BBD) was used to determine operating parameters namely initial pH (2-10), oxidant dosage (5-85 mg/g TSS), and Fe 2+ to oxidant ratio (0.2-2) and disintegration time (20-100 min). According to ANOVA results, determination coefficient (R 2 ) was found 93.2%, 76.3%, 84% and 84.8% for each oxidant, respectively. Under the optimum operating conditions, disintegration degree in terms of chemical oxygen demand (DD COD ) was calculated 11.09%, 5.23%, 10.75%, and 5.34%, respectively. Furthermore, bound water reduction (BWR) of waste sludge increased after the disintegration process, and 33.52%, 24.56%, 44.63% and 32.80% BWR values were obtained under the same operating conditions. Results show that the higher DD COD and BWR values were achieved by calcium hypochlorite and peroxymonosulfate treatment.

“…While water oxidation produces hydrogen and oxygen gas in the anode, hydrogen gas and hydroxide in the cathode are produced by reducing water. In addition, oxidation produces a strong oxidizing hydroxyl radicals and forms of dehydrogenated and hydroxylated species can react with organic pollutants [30][31][32][33]. Accordingly, when leachate enters the anode and cathode from the region between the reactor wall and the anode, it is subjected to electrokinetic conditions and organic oxidation occurs.…”

Herein, landfill leachate containing high amount of organic matter, which is quite difficult to treat, was first treated using the new submerged membrane electro-bioreactor (SMEBR) system. Aluminum (Al) electrode was used for the treatment of leachate in the SMEBR and Al accumulation was detected. This study aims to examine Al accumulation in the treatment of leachate with high organic content in the SMEBR system. The Al values obtained were plotted on a graph using MS Excel, and Mann-Whitney U test was used to determine whether there is a statistical difference between the observed Al values. Also, correlations between Al accumulations and conductivity and TOC in SMEBR and SMBR were evaluated. Resultantly, it was found that relationship between Al and conductivity is very weak, correlation between Al and TOC% is a weak-moderate, the Al accumulation in the SEMBR has a linear relationship with time and there is a very strong correlation between the two variables (R 2 = 0.7591). Its correlation with time in the SMBR is moderate (R 2 = 0.3316). MS Excel 2016 and Minitab 16.0 programs were utilized in the statistical analyses.
