What is the actual process of the residential reverse osmosis system?
Depending on the system you have, the raw tap water 1) flows through a 5-micron particle filter to remove rust, dust and other sediments, 2) flows into a carbon briquette cartridge filter, which removes 98% of the chlorine and organic chemical, 3) flows through a carbon block filter to filter multi-chemical compounds and suspended solids, 4) flows through a reverse osmosis membrane (TFC) that separates 95-99% of the dissolved contiminants from the water molecules, which are washed down the drain, 5) flows through a small carbon filter to remove the remaining trace of chemicals, taste and odor (see Flow Chart), and 6) flows into a tank for storage. Inside the tank is a balloon -like rubber diaphragm, pre-charged with 7-10 pounds of air. As the tank fills, the air pressure increases and pushes the water out when the faucet is opened.
