Evaluation of combined membrane and UV filtration shows improved water quality, indicating a practical solution for communities.

The aim is to evaluate the effectiveness of combined membrane and ultraviolet filtration systems in enhancing drinking water quality.
Analyzed raw and treated water samples for quality parameters such as TDS, turbidity, color, pH, nitrate, and nitrite.
Used standardized methods from the Indonesian Ministry of Health to assess the effectiveness of the filtration system.
TDS decreased from 172 mg/L to 122 mg/L.
Turbidity reduced significantly from 136 NTU to 11 NTU.
Color improved from 36.4 PtCo to 12.2 PtCo.
pH increased from 5.85 to 6.26, approaching safe drinking levels.
Nitrate and nitrite levels remained below maximum limits after treatment.
