Turbo Pressure Boost Turbo Pressure Boost -- ExampleExampleSWRO plant, Membrane feed flow 41.6 m3/h, conversion 40 %, membrane feed pressure 64 bar,
brine pressure 62 bar, brine back pressure of 0.5 bar. What is the pressure boost???
HALOHALO--225 = (0.57) x (0.60) x (62 225 = (0.57) x (0.60) x (62 –– 0.5) = 21 bar boost0.5) = 21 bar boost
