The Effect of Pump Pressure in Improving the Quality of Peat Water Treatment Throught Nanofiltration: Effectiveness

Abstract

Objective: The study aimed to evaluate the effectiveness of nanofiltration at different pressures in reducing turbidity, colour intensity, organic matter, Fe, TDS, as well as Total Coliforms and E. coli in peat water.

Methods: This research employed a quasi-experimental design with a quantitative approach. The tested pressures were 30 Psi, 40 Psi, and 60 Psi, each repeated 9 times, resulting in a total of 27 samples. The tested parameters included turbidity, colour intensity, organic matter, Fe, TDS, Total Coliform, and E. coli. Sample analysis was conducted at the Laboratory of Standardisation and Industrial Service Agency in Pontianak, West Kalimantan. Data analysis was performed using One-Way ANOVA and Kruskal-Wallis tests.

Result: The effectiveness of nanofiltration, such as turbidity (98.98%) with a p-value of 0.539>0.05, TDS (92.04%) with a p-value of 0.0567>0.05, organic matter (97.18%) with a p-value of 0.808>0.05, and Fe (90.83%) with a p-value of 0.613>0.05. Statistical tests indicate no significant difference between pressures (p-value 0.05).

Conclusion: Variations in pump pressure have a significant effect on the quality of peat water in achieving clean water standards. To achieve drinking water standards, further processing such as reverse osmosis is needed.
