Reverse osmosis, also known as hyperfiltration, is a process similar to membrane filtration that when used on water eliminates the presence of most heavy metals and contaminants. However, there are key differences between filtration and reverse osmosis. During the filtration process, the water is strained through a membrane which allows the filter to catch some but not all unwanted particles in the water. When osmosis is applied, it incorporates diffusion, the process of moving molecules from a region of higher concentration to a region of lower concentration. In the process of osmosis the molecules are water, and pressure forces the water across a semi-permeable membrane which allows the passage of water, but not ions (for example: Na+, Cl-) or larger molecules like glucose, urea, or bacteria. With reverse osmosis rather than moving molecules from a region of higher to lower concentration, molecules are moved from a lower to higher concentration. At the end of the process the solute, (unwanted contaminants) remain on one side, and the pure solvent (clean water) passes to the other side.
Benefits of Reverse Osmosis
•Can reduce levels of common parasites such as giardia and cryptosporidium, fluoride, arsenic, asbestos, atrazine, benzene, chlorides, silver, sulfide, cysts, hexavalent chromium, trivalent chromium, copper, cadmium, radium, radon, selenium and more.
•Uses no electricity
•Can provide clean, sparkling, fresh water in your home
•Brewed drinks that use water such as coffee, tea, or soups may have richer flavor
•Low mineral content of the water can keep household appliances like steam irons and humidifiers working longer and more efficiently
•Save a large amount of money yearly, by cutting spending on bottled water
Multi-Pure’s MP750 Plus RO combines Multi-Pure’s renowned carbon block filter technology with the reverse osmosis technology, making it the most technologically advanced System in the world today. The Multi-Pure MP750 Plus RO is the ONLY device certified under NSF/ANSI Standards 42, 53, and 58 to reduce: Fluoride, Nitrates/Nitrate, Arsenic V, Chloramine, PCBs, Toxaphene, Chlordane, Lead, Mercury, and many other contaminants.
The Multi-Pure MP750PlusRO Unit is easy to install and simple to operate. It uses no electricity and the impurities removed through the reverse osmosis process are flushed down the drain. The pre-filter component provides 5 micron filtration to remove large particulate matter and extend the life of the reverse osmosis membrane. The reverse osmosis component reduces the level of Total Dissolved Solids (TDS), rust, dirt scale, and organic tastes and odors. The processed water is conveniently stored in a 3 gallon pressurized tank which is small enough to fit neatly under your sink. Multi-Pure’s MP750PlusRO Unit includes pre-filter, RO membrane, and Multi-Pure’s Model MP750SB as a post-filter, giving you the highest quality water possible.
