This study aimed to secure a supply of reclaimed wastewater using the Birm filter to eliminate the manganese during the pretreatment stage. Another purpose was to analyze the characteristics of the UF membrane fouling. In this study, there were no investigations on the residual chlorine level, the chloride criterion, and the ABS criterion. Owing to these missing criteria, the quality of the reclaimed wastewater was found to be substandard when compared to the required quality standards for reclaimed water. However, it complied with the SS, BOD, turbidity, and chromaticity standards and was therefore still suitable for landscaping, cleaning that does not involve human contact and industrial applications. The water treatment facilities in industrial areas did not seem to need the Birm filter, since the removal of Mn ions in the wastewater was not effective enough. However, when manganese removal is required, injection of calcium permanganate or chlorine can remove the oxidation. The study of the UF membrane fouling involved SEM and EDX analyses, which indicated that carbon and oxygen ions accounted for 47% of the overall composition, but there was no trace of inorganic matter. Furthermore, the difference in the recovery rate of the fouled membrane between acidic and alkali cleaning was more than 78%. In conclusion, the results indicated that organic matter contributes to membrane fouling whereas inorganic matter has no effect.
