Q: What is Reverse Osmosis (RO) System ?
RO Systems is a Home Drinking Water System that uses the principle of reverse osmosis to remove 95-99% of all the mineral and chemical contaminants from raw tap water. PurePro products gives you the quality of bottled water with the convenience of a faucet mounted on your kitchen sink.

Q: How does Reverse Osmosis differ from a Water Filter ?
Ordinary water filters use a screen to separate only particles of dirt sediment from water. Reverse osmosis employs a semipermeable membrane that removes not only particles but also an extremely high percentage of dissolved contaminants-molecule by molecule- from raw tap water.

Q: What is the membrane and how does it work ?
The membrane consists of several thin layers or sheets of film that are bonded together and rolled in a spiral configuration around a plastic tub (This is also known as a thin film composite or TFC membrane.) The material of the membrane is semipermeable : it allows water molecules pass through while acting as a barrier to dissolved solids (i.e.: mineral chemical contaminants). When the feed water stream passes across the surface of the membrane, the PurePro molecules penetrate the membrane surface, working their way around the spiral and collecting in the center tube. The remaining contaminants are concentrated and washed from the surface of the membrane down the drain.

Q: Why use Reverse Osmosis to purify water?
Reverse osmosis have become the water purification method of choice for drinking water in many households and bottling plants throughout the world. No wonder, as reverse osmosis has become the best and most efficient method to purify polluted and undesirable water into pure and tasty water.

Q: Will R.O. remove Sodium from the water ?
YES! Reverse Osmosis was originally designed to make sea water drinkable for the navy. It is ideal for anyone on a low sodium diet.

Q: Does R.O. remove Bacteria ? Cryptosporidium ?
YES! An R.O. membrane has a pore size much smaller than bacteria virus, pyrogen or the cryptosporidium parasite. When functioning properly it will remove all microorganisms from tap water and produce sterile water . 

Q: What factors affect the quantity and the quality of the water produced ? 
1. PRESSURE. The greater the water pressure, the better the quantity and quality of the water produced. Water pressure of 60 psi ideal. RO system include one booster pump can make sure the water pressure.
2.TEMPERATURE. 76*F is the ideal water temperature for R.O. 40*F water will cause the production of R.O. water to fall to half of that at 76*F. The maximum water temperature recommended is 85*F.
3.TOTAL DISSOLVED SOLIDS (TDS). The higher the amount of dissolved contaminants in the water, the lower the quantity of water produced. A high level of TOTAL DISSOLVED SOLIDS can be overcome with additional water pressure.
4. MEMBRANE. Different membranes have different characteristics. Some produce more water than others; some have better contaminant rejection capabilities; some have greater resistance to chemical abrasion for longer life.
