Frequency Asked Questions (FAQ)

Biofresh 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 Biofresh products gives you the quality of bottled water with the convenience of a faucet mounted on your kitchen sink.

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.

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

Reverse Osmosis is the reversal of the natural flow of osmosis. In a water purification system, the goal is not to dilute the salt solution, but to separate the pure water from the salt and other contaminants. When the natural osmotic flow is reversed, water from the salt solution is forced through the membrane in the opposite direction by application of pressure-thus the term REVERSE OSMOSIS. Through this process, we are able to produce pure water by screening out the salts and other contaminants.

YES! Reverse Osmosis was originally designed to make sea water drinkable for the navy. It is ideal for anyone on a low sodium diet.

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.

The PurePro System contains a quality carbon filter which will remove more than 98% of organic chemicals from the water. These include THMs(chloroform), DBCP, lindane, TCEs(trichloroethylene), PCEs(tetrachloroethylene), carbon tetrachloride chlorine, In addition to these organic chemicals, below is a partial list of other contaminants removed by the Re1812-70 TFC membrane. The percentage of removal shown below is a conservative estimate.
