Electrocoagulation has been employed as a treatment technique for treating various wastewaters. This study focuses on the performance of electrocoagulation process for the treatment of Palm Oil Mill Effluent (POME) and Paint Wastewater (PW) using iron electrodes. POME obtained from local palm oil producers and PW from a paint industry, both in Enugu state of Nigeria, were treated by electrocoagulation using two iron electrodes. Effects of current density, electrocoagulation time, pH, and temperature were studied. Results revealed that this process could reduce the concentration of Total Suspended and Dissolved Solids (TSDP), in both POME and PW. The highest removal efficiencies of 65% and 76% were obtained for POME and PW, respectively, at 3 Amps, 60min, pH of 10, and 50°C for POME and 3 Amps, 60min, pH of 6, and 60°C for PW. Of the two kinetic models studied, second-order kinetic model fitted best to the obtained experimental kinetic data. From this study, it can be concluded that electrocoagulation is effective in the treatment of POME and PW.

The purpose of current study was to examine the ability of electrocoagulation in decreasing chemical oxygen demand (COD) and total suspended solid (TSS) constituted in palm oil mill effluent. Bench-scale batch reactor containing two aluminum or steel plates (10 cm width × 30 cm height with 0.1 cm thickness) serving as electrodes with the interval distance of 3 cm was set up. The wastewater with COD concentration of 68,425 mg L-1 was treated in the reactor under the varied direct currents (0.3-1.3 A) and contact time (30-120 min). Sodium chloride was added to the wastewater to obtain the final concentration of 2 g L-1 (conductivity of 10 ms) prior to being fed into the reactor. The results showed that higher treatment efficiency when the aluminum was used as electrodes compared to the steel. COD removal efficiency was directly proportional to the contact time. The maximum COD and TSS removal observed at 1.3 A current input and 60 min contact time are 74.1 and 77.0%, respectively.

Malaysia has been recognized in recent decades as one of the world's leading palm oil producers and exporters. The number of palm oil mills multiplies each year, increasing the capacity of fresh fruit bunch waste or effluent discharged. Countless numbers of research and development, as well as implementation, have been dedicated to advancing the pollution control technologies. Most of the research is to treat and manage liquid and solid waste generated from palm oil mills. The main reason for such tremendous efforts is that the waste coming from palm oil mills has been declared as one of the pollution sources in the world. Thus, the purpose of this study was to utilize treated palm oil mill effluent (POME) sludge from the electrocoagulation process to produce bricks. Here, three different dilution rates, which was 60%, 90% and 100% of POME concentration have been analyzed in the electrocoagulation process, respectively. After the electrocoagulation process, the characteristics of POME effluents were evaluated, and the treated POME sludge was collected. Instead of being discarded after the treatment, the treated waste sludge from the electrocoagulation process was used to make bricks. Three different bricks labelled (A, B and C) from treated POME sludge from the electrocoagulation process (60%, 90% and 100%) were fabricated. These bricks have been analyzed based on the JKR Standard Specifications for Building Works. Data obtained showed that the compressive strength for the bricks (A, B and C) after seven days were 6.076, 8.233, and 6.344 N/mm2. Meanwhile, the bulk density of the bricks (A, B and C) were 2247.92, 2233.95, and 2094.33 kg/m3. The results showed that the compressive strength for these brick samples had met the JKR Standard Specification for Building Works of 5.2 N/mm2. It can be deduced that the bricks from treated POME can be a greener product compared to the traditional bricks. Moreover, the concept of a circular economy is adapted in this study to eliminate waste for a long-term sustainable environment.

As the ponding system used to treat palm oil mill effluent (POME) frequently fails to satisfy the discharge standard in Malaysia, the present study aimed to resolve this problem using an optimized electrocoagulation process. Thus, a central composite design (CCD) module in response surface methodology was employed to optimize the interactions of process variables, namely current density, contact time and initial pH targeted on maximum removal of chemical oxygen demand (COD), colour and turbidity with satisfactory pH of discharge POME. The batch study was initially designed by CCD and statistical models of responses were subsequently derived to indicate the significant terms of interactive process variables. All models were verified by analysis of variance showing model significances with Prob > F < 0.01. The optimum performance was obtained at the current density of 56 mA/cm2, contact time of 65 min and initial pH of 4.5, rendering complete removal of colour and turbidity with COD removal of 75.4%. The pH of post-treated POME of 7.6 was achieved, which is suitable for direct discharge. These predicted outputs were subsequently confirmed by insignificant standard deviation readings between predicted and actual values. This optimum condition also permitted the simultaneous removal of NH3-N, and various metal ions, signifying the superiority of the electrocoagulation process optimized by CCD.
