“…The TDS value generally decreases with the length of the electrocoagulation time. This result is in accordance with the results of Osman's et al [11] and El-Ezaby et al [12] which successively performed electrocoagulation on tanning wastewater and wastewater from an orange juice industry. The lowest TDS value was found when the wastewater was treated for 40 minutes, which was 209 mg/L.…”

The ablution ritual performed by Muslims before praying requires large amounts of clean water (3.9 L - 4.42 L/person). This is a challenge that needs to be addressed, as in some places, water is a scarce commodity. This study aims to treat ablution wastewater at Masjid Al-Bukhari UIN Raden Mas Said Surakarta using electrocoagulation. The treated water is expected to be reused for ablution rituals in the mosque. Laboratory-scale research methods were performed to treat ablution wastewater. The effect of electrolysis time was evaluated to determine efficiency of the method on the parameters of pH, temperature, total dissolved solid (TDS), conductivity, and ammonia level. Interestingly, ablution wastewater treated using electrocoagulation meets clean water quality standards. This means that the water is safe to reuse for ablution activities in mosques. The electrolysis time has a significant effect on the increase of pH value and the decrease of ammonia level. TDS levels decreased to 65.3% when treated for 40 min. Meanwhile, the conductivity value decreased to 526 µS/cm from the initial value of 1108 µS/cm when the water was treated for 60 min. Statistically, electrolysis time has a significant effect on the decrease of TDS, conductivity, and ammonia levels (α<0.05).

“…Therefore, the best experiments were employing the EC process. One EC investigation was carried out in a system for treating an effluent generated by a guava juice manufacturing process, 194 with a COD index between 2582 and 3685 mgo 2 •L −1 and with turbidity between 119.0 and 201.0 NTU, with pH values between 4.7 and 5.1. The authors evaluated the effect of initial pH (4.5−9.5), electric current density (2.5−4.5 mA•cm −2 ), and treatment time (10−40 min) on the reduction of the COD index of the effluent in question by aluminum/ stainless-steel electrodes.…”

Electrocoagulation (EC) is an efficient treatment method that involves the electrodissolution of anodes, the formation of coagulants in situ, and the production of hydrogen at the cathode, facilitating the removal of pollutants by flotation. Industry in general aims to reduce the contaminant load, expressed as chemical oxygen demand (COD), and EC effluent treatment is particularly effective in this process. The development of EC processes has been an efficient alternative for the treatment of effluents with high pollutant loads, such as tannery, pulp and paper, textile, beverage, and food industries, and many demonstrate the potential for application in car wash effluent. This study presents a review of the use of EC for the treatment of various effluents containing COD, OGs, surfactants, color, and turbidity, but with a greater focus on the vehicle washing sector. It also discusses the factors that influence the efficiency of EC and the main discussions of the authors. Presently, the investigations of studies already carried out show that the performance of the EC process is dependent on many relationships and factors, such as the type of material constituting the electrode, the electric potential difference, the electric current density, the distance between electrodes, the surface area of the electrodes, the pH, the initial concentration of contaminants, the conductivity and the treatment time. The review demonstrated that the EC process has been employed in the treatment of many types of effluents and with relatively high efficiency rates, in general, between 60.0% and up to 90.0%, aiming at the reduction of the COD indexes, the reduction from 60.0% up to 99.0% of color content, the 87.0% reduction of chromium. In turn, for turbidity, it varied on average from 44.0 to 99.0%. For other parameters such as MBAS and OGs, in most studies, the reduction exceeded 90.0%.

“…TDS levels tend to decrease during the electrocoagulation process, although initial readings are not always consistent due to settling and sedimentation (Idusuyi et al, 2022). Other research has also shown that the longer the electrocoagulation time, the higher the TDS decrease rate (El-Ezaby et al, 2021). Therefore, it is important to optimize the electrocoagulation time to achieve effective results in reducing TDS levels in wastewater.…”

Eutrophication is a natural phenomenon in aquatic ecosystems that causes algae and other aquatic plants to overproduce. This process can benefit the ecology in tiny amounts, but too many nutrients can generate hazardous algal blooms and kill fish and other aquatic life. To prevent eutrophication and sustain aquatic ecosystems, agricultural waste water like microalgae production wastewater must be treated. The goal of the project is to get nitrogen and phosphorus out of the wastewater from growing microalgae, which is an agricultural waste water. One way to recover nutrients from wastewater is electrocoagulation. This procedure uses an electric current to create microscopic gas bubbles that collect and remove pollutants from wastewater. According to this study, electrocoagulation reduces phosphate and nitrate in microalgae culture wastewater. Phosphate concentration dropped by 90.20% in the 15th minute, while nitrate concentration dropped by 36.19% in the 30th minute. These reductions may be caused by struvite formation and nitrate conversion to nitrogen gas. This study demonstrates that electrocoagulation is a potential technology for recovering nutrients from agricultural waste water and reducing aquatic ecosystem eutrophication.
