Abstract
The primary goal of this research is to investigate the effectiveness of using Ammonium Biflouride(ABF) as an anti-scaling agent in improving the performance of the RO membranes. ABF was used as on-line dosing with different doses for mitigation of scaling caused by silica (SiO2) on RO membranes. To study the efficiency of the anti-scaling agent, Scanning Electron Microscopy & Energy Dispersive X-ray Spectroscopy (SEM-EDS) were performed for all phases before and after using the anti-scaling agent on the used RO membrane surface. The main parameters measured were: silica, TDS; Flux loss was observed for the cross-flow RO membrane after filtration.ABF doses used were: 2, 4, and 6 mg /l at constant pH = 6 and the optimum dose were found to be 4mg/L
