Osmosis Drinking Water Frequently Asked Questions... |
What is Reverse Osmosis? Reverse osmosis, also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as dissolved individual ions from a solution. Reverse osmosis is used to purify water and remove ions and dissolved organic molecules. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing. The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications that are currently in place. Reverse osmosis uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most reverse osmosis technology uses a process known as crossflow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected species away from the membrane, in a concentrated brine reject water. The process of reverse osmosis requires a driving force to push the fluid through the membrane, and the most common force is pressure from a pump. The higher the pressure, the larger the driving force. As the concentration of the fluid being rejected increases, the driving force required to continue concentrating the fluid increases. Reverse osmosis is capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 daltons. The separation of ions with reverse osmosis is aided by charged particles. This means that dissolved ions that carry a charge, such as salts, are more likely to be rejected by the membrane than those that are not charged, such as organics. The larger the charge and the larger the particle, the more likely it will be rejected.

| What
is a R.O. system? A typical system consists of:
One or more Pre-filters to remove silt, iron, chlorine or other particulate matter. A membrane to remove raw water contaminates. A pressure sensitive hydraulic on/off pressure valve to send pre-filtered water to the membrane to make treated water for storage. A small storage tank for treated water. May include a post-filter to polish stored water and to maximize its taste just prior to consumption. |

Can I hook up the RO to my ice maker? Yes
- in most case we can connect directly to your refrigerator. Connecting
the system will extend the life of your ice maker and make great tasting
ice. Turn your fridge into a Culligan Water & Ice Machine. |
|||
Is RO water really as good as bottled?
"bottled water ... without the bottle". |
|||
Does the system require any maintenance or service? Yes
- Every drinking water system requires service approximately every 12-24
months. We schedule Total System Replacements every 18 months ... it's
like getting a new system every time. If for any reason you need service
just call. We will come and it won't cost you anything. 100% Total Service
is included so you can always be assured of the highest quality water. |
