Abstract
The pulp and paper industry wastewater contains organic compounds such as lignins, resins, tannins, polysaccharides, alcohols and carboxylic acids. Pulp and paper liquid waste cannot be disposed of immediately because it can affect drinking water sources, endanger human health and cause unpleasant odors so that the waste must be treated first before being disposed of into the environment. The methods that can be used in the treatment of oily wastewater are ceramic membrane technology and electrocoagulation. The purpose of this study was to determine the effectiveness of the electrocoagulation-membrane combination method in treating pulp and paper wastewater in terms of the values of BOD, COD, TSS, pH and color. The application of this combined membrane and electrocoagulation method uses activated carbon from avocado seed waste and iron as electrodes at various variations, namely voltage (5 and 10 V), flow rate (1 and 3 L / Min), pressure (5 and 10 Psig) and processing time (30, 60 and 90 minutes). The results showed that the electrocoagulation-membrane method was effective in treating pulp and paper wastewater. After processing, the best operating conditions for each membrane were obtained. A pressure of 5 psig with a flow rate of 1 L / minute for membrane 1, a pressure of 5 psig with a flow rate of 1 L/minute for membrane 2 and a pressure of 5 psig with a flow rate of 3 L/minute for membrane 3.Based on the best operating conditions for each membrane , combined with the best operating conditions of the electrocoagulation method, namely a voltage of 10 V and an operating time of 90 minutes. The lowest COD and TSS values were obtained on membrane 2, namely 21 mg/l and 29 mg/l. The lowest BOD and color values were obtained on membrane 1, namely 27 mg/l and 42 TCU. The lowest pH value obtained on membrane 3 is 6.09.
