ANALISIS KARAKTERISTIK MEMBRAN PENGOLAHAN AIR DARI BAHAN POLYVINYLIDENE FLUORIDE (PVDF) DENGAN PENAMBAHAN PERAK NITRAT

Clean water is essential for human life and sustainable development. To meet the needs of various households and the demands of an ever-evolving lifestyle, the demand for clean water continues to increase. Pollution and environmental damage caused by the disposal of domestic and industrial wastewater are among the factors contributing to the decline in water resource quality, which in turn leads to a scarcity of clean water sources. Membranes have been used in water purification processes for several years. Membranes are well-suited for clean water treatment because they are inexpensive and efficient. This study aims to examine the morphology of membranes, hydrophilic properties, mechanical strength, and filtration efficiency of Polyvinylidene fluoride (PVDF) mixtures modified by adding Silver Nitrate (AgNO₃) as an antibacterial agent and using a DC electric field printing method of 20 Kv. The tensile test results show that the highest maximum stress at 1 wt% reached 4.194 N/mm², while decreasing to 3.828 N/mm² (1.5 wt%) and 1.847 N/mm² (2 wt%) due to particle agglomeration that weakened the structure. Clean Water Permeability (CWP) testing recorded an optimal flux of 25.059 L/m².h.bar at 1 wt%, decreasing to 21.374 L/m².h.bar (1.5 wt%) and 14.004 L/m².h.bar (2 wt%) due to pore blockage. SEM analysis confirmed uniform pores with minimal agglomeration at 1 wt%, while higher concentrations caused clumping and reduced porosity, making 1 wt% the ideal composition. Thus, the most effective AgNO₃ concentration is 1 wt% in PVDF membranes, as it produces the highest tensile stress (4.194 N/mm²), optimal CWP flux (25.059 L/m².h.bar), and uniform pore structure with minimal agglomeration based on SEM analysis.
