Fouling behaviour study of fish farm effluent treatment on ultrafiltration membrane / Sivasangary Ragupathy

Abstract Dalam teknologi membran, pencemaran membran adalah salah satu masalah utama. Ia menyebabkan kemerosotan fluks. Oleh itu, dalam kajian ini, tingkah laku pencemaran membran bagi ladang ikan rawatan efluen menggunakan membran ultrafiltration telah dikaji. Membran yang digunakan dalam kajian ini adalah membran hidrofilik disintesis sendiri. Kesan keadaan suapan yang berbeza, kesan kadar suapan aliran yang berbeza (4L / min, 6L / min dan 8L / min) dan tekanan suapan yang berbeza (0.4atm, 0.8atm dan 1.2atm) prestasi membran dan pencemaran membran telah dikaji. Ia telah didapati bahawa fluks adalah lebih 0.31 L/m2.hr tinggi bagi efluen selepas filtrasi berbanding dengan efluen sebelum filtrasi. Fluks permeat meningkat secara bukan linear dengan tekanan suapan, ini menunjukkan bahawa pencemaran membran mendominasi profil fluks. Fenomena pencemaran membran telah disahkan lebih liang disekat terutama pada tekanan operasi tinggi iaitu 1.2 bar. Fluks didapati optima pada kadar suapan aliran 6L/min dan tekanan suapan 1.2atm. _______________________________________________________________________________________________________ In membrane technology, membrane fouling is one of the major drawbacks. It causes flux declination. Thus, in this study, the fouling behavior of fish farm effluent treatment on ultrafiltration membrane was studied. The membrane used in this study was a self-synthesized hydrophilic membrane. The effect of different feed conditions, different feed flowrate (4L/min, 6L/min and 8L/min) and different feed pressure (0.4atm, 0.8atm, and 1.2atm) on the membrane performance and membrane fouling were studied. It was found that the flux was higher for pre-filter effluent by 0.31 L/m2.hr compared to effluent before pre-filtration. The permeate flux increased non-linearly with feed pressure which showed that fouling is dominating the flux profile. The fouling phenomena were further confirmed to be pore blocking especially at high operating pressure (1.2 bar). It was found the flux profile was the highest at optimum feed flowrate 6L/min and transmembrane pressure.
