Abstract
Pertumbuhan jumlah pasien gagal ginjal kronik mendorong meningkatnya kebutuhan air bersih untuk proses hemodialisis, yang menghasilkan limbah air dialisat bekas dengan kandungan urea dan kreatinin yang tinggi. Teknologi membran merupakan teknologi yang potensial untuk mendukung regenerasi air dialisat yang berkelanjutan. Tujuan dari penelitian ini adalah untuk menyelidiki potensi penggunaan membran serat berongga PES/PVP dengan menggunakan pengisi HFO untuk memisahkan urea dan kreatinin pada air dialisat bekas hemodialisis sintetik. Fabrikasi membran dilakukan menggunakan metode non-solvent induced phase solution (NIPS) dalam bentuk modulasi serat berongga. Membran hasil fabrikasi dikarakterisasi menggunakan X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), dan Water Contact Angel (WCA). Kinerja pemisahan urea dan kreatinin juga turut dikaji. Studi ini menemukan bahwa dengan penambahan 5% berat HFO kedalam membran PES/PVP akan memiliki performa yang cukup bagus. Nilai fluks urea sebesar 176,97 L m-2 h-1 dengan besar rejeksi urea 54,81%. Nilai fluks kreatinin sebesar 105,83 L m-2 h-1 dengan rejeksi kreatinin sebesar 74,27%. Penentuan konsentrasi urea dan kreatinin (1600 mg/L dan 100 mg/L) mengacu pada kandungan asli pada air dialisat bekas hemodialisis. Hal ini menjelaskan bahwa membran PES/PVP dengan HFO sebagai pengisi berpotensi untuk dikembangkan lebih lanjut pada aplikasi regenerasi air dialisat nyata di masa depan.

The increase in the number of chronic kidney failure patients has led to a growing need for clean water for hemodialysis, which produces waste dialysate containing high levels of urea and creatinine. Membrane technology is a promising technology for supporting the sustainable regeneration of dialysate water. The objective of this study is to investigate the potential use of PES/PVP hollow fiber membranes with HFO fillers for separating urea and creatinine in synthetic hemodialysis waste dialysate water. Membrane fabrication was performed using the non-solvent induced phase solution (NIPS) method in the form of hollow fiber modulation. The fabricated membranes were characterized using X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), and Water Contact Angle (WCA). The study found that adding 5% by weight of HFO to the PES/PVP membrane resulted in satisfactory performance. The urea flux value was 176.97 L m-2 h-1 with a urea rejection rate of 54.81%. The creatinine flux value was 105.83 L m-2 h-1 with a creatinine rejection rate of 74.27%. The determination of urea and creatinine concentrations (1600 mg/L and 100 mg/L) was based on the original content in the dialysate water from hemodialysis. This indicates that the PES/PVP membrane with HFO as a filler has potential for further development in real-world dialysate water regeneration applications in the future.
