Abstract
The Jagir River has experienced a decline in water quality due to domestic and industrial activities, with pollutant parameters such as TDS, turbidity, and total coliform exceeding the quality standards. This study aims to analyze the effect of the operating duration of PVC ultrafiltration membrans coated with Titanium Dioxide (TiO2) on the removal capability of TDS, turbidity, and total coliform parameters, as well as the effect of pressure variations and TiO2 coating on the flux rate. This research method involves adsorption pre-treatment using granular activated carbon (GAC) before the ultrafiltration process with varying pressures (1; 1.5; 2 bar) and operating durations (15 – 75 minutes). The results showed that adsorption pre-treatment was able to reduce turbidity (95.45%), total coliform (59.93%), and TDS (18.89%). The combination of 2 bar pressure with an operating duration of 75 minutes resulted in the highest removal efficiency for all three parameters, namely total coliform (100%), turbidity (96.90%), and TDS (18.84%). TiO2 coating increases the membran flux rate at the start of operation, especially at high pressures, but decreases drastically over time due to fouling. The study concluded that the combination of adsorption and ultrafiltration with appropriate variations in duration and operating pressure can increase the effectiveness of pollutant removal and maintain membran performance. Furthermore, coating with titanium dioxide can increase the membran flux rate when operated at the appropriate pressure.
