Reverse osmosis is a water treatment technique that allows to produce large quantities of demin water in a constant and reliable manner.
How does reverse osmosis work?
A reverse osmosis installation produces pressure on an aqueous solution, which is in contact with a semipermeable membrane. This pressure is larger than and opposite to the osmotic pressure. Because of this pressure, water permeates through the membrane (cfr. diagram). The main part of the solution’s substances are stopped by the semipermeable membrane.
Reverse osmosis is a physical process requiring no chemical products. Thanks to the modern membranes up to 99.6% of the dissolved substances is eliminated without regular interruptions for cleaning or maintenance.
The permeate contains almost no more dissolved substances. Without a reverse osmosis installation, these particles can lead to a production interruption (or in any case to a less efficient production).
A reverse osmosis appliance eliminates almost all:
* Mineral salts
* Heavy metals
* Bacteria, viruses and pyrogenic

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.

Reverse osmosis (RO) is used to reduce dissolved solids from feed waters with salinities up to 45,000 ppm TDS (total dissolved solids). Municipalities and industrial facilities are able to use RO permeate as a consistently pure drinking water supply and to transform drinking water to high purity water for industrial use at microelectronics, food and beverage, power, and pharmaceutical facilities. The technology is also very effective at removing bacteria, pyrogens, and organic contaminants.
Reverse osmosis separation technology is used to remove dissolved impurities from water through the use of a semi-permeable membrane. RO involves the reversal of flow through a membrane from a high salinity, or concentrated, solution to the high purity, or "permeate", stream on the opposite side of the membrane. Pressure is used as the driving force for the separation. The applied pressure (P) must be in excess of the osmotic pressure of the dissolved contaminants to allow flow across the membrane.

Size Matters! One 16" instead of 4 x 8" membranes equates to less O-rings, permeate connectors that can leak, and still produces more water per m2 of membrane surface area!
GrahamTek 16 inch RO membranes are manufactured by reputable membrane suppliers such as Hydranautics and SAEHAN who manufacturers the membranes for GrahamTek under licensing arrangements
