| Abstract | An innovative onsite blackwatertreatment system by integrating conventional septic tank (CST) and up-flow anaerobic reactor (UF) has been proposed as a sustainable option for the green school concept. This study demonstratedthe functionality and performance,under actual conditions, of the innovative onsite blackwater treatment system at thegreen schoolin Bangkok, Thailand. Four pilot-testing units of the integrated CST and UF (CST+UF 1-4) system were installed at the green school (IPC Green International Preschool and Nursery, Ramkhamhaeng 21). During the 4-month operation,the integrated CST and UF system received blackwaterfrom 4 publicflush toilets (6-10 L water/flush), eachwith more than 60 users/day.The effluent COD and BOD5concentrations of the integrated CST and UF system could be maintained at approximately 100 and 50 mg/L, respectively, and meeting the local discharge standard of Thailand.The integratedCST and UFsystemis considered to be an innovative onsite wastewater treatment technology for alleviating the environmental concerns associated with septic tank effluent. |
