A STUDY ON EFFICIENCY OF CONDUCTIVE MATERIAL FOR WASTEWATER TREATMENT FROM HOUSEHOLDS BY ELECTROLYSIS PROCESS

Abstract

Residential wastewater is a major drainage source of wastewater generated from household activities without proper management and treatment of wastewater that impact on water quality and the environment. From the preliminary study, the wastewater treatment system by electrolysis process to treat some organic substances dissolved in water, high concentration. It used to treat wastewater after standard treatment and high cleanliness. The aim of this study was to compare the effect of wastewater treatment on three types of electrical conductivity. This research was an experimental design. We examined three conductive materials, graphite, copper and aluminum. The samples were collect before and after treatment for analysis pH, BOD (Biochemical Oxygen Demand), SS (Suspended Solids), Fat and Oil, according to the wastewater control standards in wastewater from households, Muang Surat Thani District. In wastewater treatment direct current voltage of 24 volts, was use current of 10 amperes the electrode was made of each conductive material. The results demonstrated that pH, BOD, SS and Fat and Oil of pre-treatment wastewater was 5.784, 5,231 mg/L, 0.47 mg/L and 0.063 mg/L, respectively. After treating wastewater was using graphite sheet, copper and aluminum and was the electrolytic conductors, it was find that pH equal to 5.17, 5.11, 5.20 and SS equal to 0.08, 0.11, 0.085 mg / L and BOD equal to 223, 244, 235 mg/L and Fat and Oil equal to 0.051, 0.061, 0.055 mg / L, respectively. It can be seen that when comparing the results of the parameters of household wastewater, it was find that after treatment, the results were compare between graphite, copper and aluminum. It was finding that the use of graphite sheets gave the best results. The use of graphite sheet gives the best results. This makes the water quality after treatment better than using other conductive materials. Researchers are interested in the materials used in conducting graphite sheet electricity to apply in the construction of wastewater treatment equipment. It should be increase the number of times to analyze for reliable results; it should analyze the nutrients remaining in the water after treatment for the benefit of bringing water to add other benefits, such as growing hydroponics vegetables or bringing sludge to make fertilizer.
