Abstract
Population growth increases the need for raw water supplies. Poor quality, quantity, and continuity of raw water conditions impacts to the scarcity. The problem can be solved by water treatment technology. East Flood Canal (BKT) is one of the infrastructure facilities in DKI Jakarta province has potential to become a source of raw water supply. This study aims to analyze the appropriate pre-processing technology to improve the water quality of BKT. Analytical Hierarchy Process method was used to determine the appropriate pre-treatment technology to improve the water quality of BKT. There are 3 alternative technology options, such as MBBR (Moving Bed Biofilm Reactor), MBR (Membrane Bioreactor), and Bank Filtration, while the criteria are the environment, social, and economic. The questionnaire were weighted, reviewed consistently, and analyzed descriptively. The results showed that the MBBR technology earns the highest weight of 0.51, MBR is 0.38, and the BF is 0.12. Based on environmental and social aspect, MBBR needs the smallest area, hence it can be easily approved by the people. In economic aspect, the investment of MBBR is more expensive, however the operational is affordable. In conclusion, MBBR technology is the most appropriate technology for water treatment of East Flood Canal.
