The process is called "Reverse" Osmosis since it requires pressure to force pure water across a membrane, leaving the impurities
The reverse osmosis process uses a semi-permeable membrane to separate and remove dissolved solids, organics, pyrogens, submicron collodial matter, viruses, and bacteria from water. The process is called "Reverse" Osmosis since 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, thus providing safe, pure water.
CHOOSING THE RIGHT REVERSE OSMOSIS SYSTEM To select the right Reverse Osmosis system, there are few 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. All models are indicate the gallons per day (GPD) of product water.
