The Effect of Pressure Application on Reverse Osmosis Membrane Performance in The Brackish Water Treatment Process
Keywords:
Reverse Osmosis, Fluxs, RejectionAbstract
One of the clean water treatment technologies uses reverse osmosis membranes. Reverse osmosis is a water purification process that, in principle, uses the help of hydrostatic pressure so that the solvent can move from a high-concentration solution to a low-concentration solution. This experiment was conducted using 9% brackish water and applying pressure to the membrane of 50, 54, and 58 psi. Observations were made on pre-treatment, permeate, and retentate flow samples. The results of the observations showed that increasing pressure would affect the performance of the RO process. This is indicated by the highest rejection and flux values obtained at a variation of 58 psi, which were 0.9989 - 0.9992 and 335.09 L/m²/hour. The application of pressure to the RO process will affect the total dissolved solids produced.
