The effectiveness of drum of wastewater treatment (DOWT) in reducing TSS of domestic wastewater

Objective: This study aims to determine the effectiveness of the Drum of Wastewater treatment (DOWT) in reducing levels of Total Suspended Solid (TSS) in domestic wastewater. Method: This study was an experiment to determine the effectiveness of Drum of Wastewa- ter Treatment (DOWT) in reducing TSS levels of domestic wastewater. It was conducted from September to October with Pretest---Postest Design. Pretest data obtained from examination of wastewater parameters before processing, while posttest data was after processing. Result: The pH level of wastewater during the measurement process is in the range between 6.12 and 6.85 where in this circumstance the bacterial microorganisms are very dominant from others. The temperature ranged from 24 to 32. The measurement results of TSS obtained an average 34 mg/L before processing and 2.85 mg/L after processing with an efficiency of 91.6%. Conclusion: DOWT wastewater treatment has been able to reduce TSS levels according to the specified quality standards.
