The Tech Inc. Batch RO Test Skid with Pressurised Work Exchanger runs true batch reverse osmosis. A pressurised work exchanger, with a free piston or bladder, holds the concentrate and lets the applied pressure follow the rising osmotic pressure through each cycle instead of staying at the highest value. Researchers use it to measure specific energy, recovery and cycle timing against conventional and closed-circuit RO.

Main components

Feed tank and cartridge prefilter
High-pressure pump on VFD with power metering
Recirculation pump
Pressurised work-exchanger vessel with free piston or bladder and position sensing
One pressure vessel for a 2.5- or 4-inch element
Pressure, flow, conductivity and temperature transmitters
PLC and HMI with phase sequencing and data logging

Applications: Desalination energy research, high-recovery brackish and seawater studies, brine concentration and teaching laboratories.
