Abstract:
The technology of reverse osmosis (RO) membrane is one of the
desalinization methods that are environmentally friendly, with lower energy
consumption and it does not need a large area to build which makes this
technology suitable to applied and competitive to applicative.
This research studies the alternative of desalinization of brackish water,
the performances of reverse osmosis membrane and the influence of operation
pressures and concentration to the membrane mechanism. Samples used in this
study are synthetic (NaCl with a concentration of 10, 20, 50 and 100 ppm). The
operation pressure of the membrane used in this research is between 0,5 and 7 bar.
The Filmtec USA model TW30-1817-75 RO membrane is utilized. The measured
parameters are fluxes and TDS. It can be conducted, from the results, that
operation pressure, the concentration of NaCl and TDS baits influence flux of the
reverse osmosis membrane in the desalinization of the synthetic brackish water.
The increase operation pressures increase the flux. The increase of NaCl and TDS
concentration decreases the flux. The maximum flux of synthetic sample of NaCl
was 52,5547 L/ m^. jam with the sample of NaCl concentration used 10 ppm,
operation pressure was 7 bar.
