“…OPCs under the optimum conditions mentioned above, were 0.07 US$/(kg color removed) and 0.4 US$/(kg COD removed). These results differ from the results of studies [76][77][78] suggesting that the use of ECF as a process for real printing and packaging wastewater treatment by RSM optimization, could be a feasible technology due to high COD and color removal efficiency and economical viability in terms of operating costs.…”

In this work, electrocoagulation-flotation (ECF) following sedimentation was applied as a printing and packaging wastewater treatment using four Al electrodes with a parallel monopolar configuration. A sedimentation process was applied after the ECF as a post-treatment phase to remove large pollutants. The simultaneous efficacy of the operating parameters initial color content (1,843.44-12,156.56 ADMI), initial pH (3.56-10.44), current density (6.02-22.18 mA/cm 2), and treatment time (5.62-74.38 min) on color and chemical oxygen demand (COD) removal efficiencies were evaluated alongside processing costs. Response surface methodology (RSM) and central composite design (CCD) optimized these key parameters to achieve the highest removal efficiencies and lowest operating costs. Based on the results analyzed by RSM-CCD, using initial color content of 5,576.38 ADMI, initial pH of 7.29, the current density of 18.49 mA/cm 2 , and treatment time of 59.76 min as optimum operational conditions can result in 97.8% and 92.1% for color and COD removal efficiencies, respectively. At these optimum conditions, operating costs (OPCs), including electrodes material and energy consumption, were 0.07 US$/(kg color removed) and 0.4 US$/(kg COD removed). The results confirm ECF-sedimentation as a promising and costeffective tool for the treatment of printing and packaging wastewater.

“…after that point (which point?) (Moosavirad, 2017). From results obtained by treating both the samples, it can be concluded that CD, pH, and IED play a role in the CCV initially and during the process any changes in above mentioned parameters also reflects the impact on CCV .…”

The effluent from the oil drilling site is a complex mixture of harmful chemicals that causes environmental impacts on its disposal. The treatment of oil drilling site wastewater has not been explored in-depth in the available literature and requires understanding about its characteristics and optimization of the treatment process. In the present study, we have optimized the electrocoagulation process with aluminum electrodes for the drill site wastewater treatment. A multi-level factorial center composite design using response surface methodology (RSM) is applied to quantify the individual and combined effect of the current density, pH and inter-electrode distance (IED) on the COD removal from the drill site wastewater and the energy consumption of the electrocoagulation process. The increasing current density shows significant increase in COD removal. A similar trend was observed with decrease in pH on COD removal. The model obtained from RSM study predicted the optimum current density, pH, and IED within the experimental range of the study. It was found that the optimum condition for DSW-1 samples for 78% COD removal is at 4.76 mA/cm2 and 4 pH, and for DSW-2, we get the COD removal of 64% at 19.04 mA/cm2 and 1.2 cm IED. The study shows that the current density is the dominant factor for the process's energy consumption and operating cost as compared to the pH and IED. The study demonstrated optimization of the electrocoagulation process in drill site wastewater treatment and could be effectively used for large-scale treatment through the electrocoagulation process.

“…The results generally are equally high for each study. Pirkarami et al [26][27][28] reported that the percentage of turbidity removal using iron as electrodes is 97%, 95% and 95% in dye, mining, and synthetic wastewater respectively. Similar trends are also identified in TDS and color.…”

The increased demand for water stimulates the use of treated wastewater as an alternative resource. However, there has been a constant concern from communities regarding the quality of the treated water. Thus, we present an investigation of community perception on reusing treated wastewater from ablution wastewater. This study aims to treat the ablution wastewater using the continuous electrocoagulation method and to investigate community perception of the treated wastewater. A laboratory experiment was conducted to observe the physical, chemical, and biological properties of the treated wastewater, while focus group discussions (FGD) with 10 respondents from two different mosques in Solo were carried out to understand the community perception if the treated wastewater to be reused for ablution water. The laboratory results showed that the electrocoagulation coupled with the chlorination process successfully diminished the wastewater's physical and chemical properties. the results meet the standards set by the Ministry of Health of the Republic of Indonesia through Regulation No. 32/2017 on Water Quality Standard for Sanitary Hygiene Purposes. On the other hand, the FGD results revealed two different perspectives regarding the application of treated wastewater. Over half of the respondents agreed to reuse the ablution wastewater, while the remaining declined. The decisions of those who agreed are highly affected by the Indonesian Ulema Council Fatwa regarding the status of the treated wastewater. Meanwhile, those who refused argued that currently, there is no urgency to use the treated wastewater since they are not aware of the seriousness of the issue. Furthermore, the respondents are also concerned about the possibility of virus contamination on the treated wastewater, making the water unsafe to be used.
