Reverse Osmosis Systems

Reverse Osmosis (RO) is a process that uses pressure applied through a membrane barrier to remove dissolved solids from a liquid. The RO process uses cross-flow filtration as compared to depth filtration. The former has three streams while the latter two. In RO the feed flows tangentially over a membrane surface and separates into permeate and concentrate. The concentrate is normally wasted except when energy recovery is viable in which case the high pressure of the concentrate is used to reduce overall power consumption before disposal.

The PACT RO normally uses a thin film composite membrane wound in a spiral configuration. The standard PACT RO package is a skid-mounted unit that includes a cartridge filter; high pressure pump; membrane cleaning pump; membrane housings (pressure vessels); membrane elements; instrumentation for flow/pressure/temperature and conductivity; PLC-based control panel and; interconnecting piping, fittings, valves and electric wiring within the confines of the skid. As standard piping used on the high pressure side (feed and concentrate) is 316 stainless steel and on the low pressure side (product) is schedule 80 PVC. However, its client’s option to request that all piping on the RO skid be 316 s/s or higher alloy steel.
