Reverse Osmosis

Reverse Osmosis separates dissolved solids, pyrogens, organics, submicron collodial matter, viruses, and bacteria from water by forcing the water through a semi-permeable membrane. This process is called "reverse" osmosis because it requires pressure to force pure water across a membrane, leaving the impurities behind. Reverse Osmosis is capable of removing 95 - 99% of the total dissolved solids (TDS) and 99% of all bacteria.

The raw water, which contains salts and impurities, is pushed into the membrane element, and the system pump forces the water through the membrane for collection in the product tube in the center of the membrane element. The water that contains impurities passes out of the element along the surface of the membrane and does not enter the product tube.


Selecting the Right Reverse Osmosis System

To select the right Reverse Osmosis system for your application, there are four primary considerations: the type of raw water, the quality of the product water required, the capacity of product water required, and any special features such as storage, repressurization, or mounting. The model numbers indicate the amount of product water each system will produce; the EPRO model numbers indicate the gallons per day (GPD) of product, and the DELTA system model numbers indicate the number of gallons per minute (GPM) of product.
