Abstract

River water is a crucial resource that continues to experience a decline in quality due to high levels of turbidity and Total Suspended Solids (TSS). This study aims to analyze the effectiveness of combining pneumatic rapid mixing and hydrocyclone flocculator technologies in reducing TSS and turbidity in river water, using a laboratory-scale experimental approach. The independent variables tested were air flow rate (70, 55, and 40 L/min) and hydrocyclone diameter (15 cm and 20 cm), with water quality parameters including turbidity, TSS, and pH. Testing was conducted using standard methods (SNI), and data analysis employed removal efficiency and two-way ANOVA statistical tests. The results showed that the optimal configuration was achieved at an air flow rate of 70 L/min and a hydrocyclone diameter of 15 cm, with turbidity reduction efficiency of 73.1% and TSS reduction efficiency of 63.8%. These findings indicate that the integration of both technologies can produce an efficient and stable coagulation-flocculation process, with potential for application in sustainable surface water treatment.
