Engineering Note: The PX-70SB is designed specifically for low-pressure desalination applications including brackish water RO, water reuse, and industrial process water. With a maximum operating pressure of 450 psi (31 bar), it provides the same isobaric energy recovery principle as the SWRO models but optimized for lower differential pressures typical in BWRO systems.
