Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules and other particles from drinking water. It is the opposite of the natural process by which moisture is taken up by living cells. With plants, special cell walls act as the membrane through which water passes, bringing with it nutrients that feed the plant. In water purification, a synthetic membrane separates water with a high concentration of contaminants from water with a low concentration. Reverse osmosis forces the water with the high concentration through the membrane to the other side using normal water pressure. Only molecules of water can easily pass through that membrane; so the water emerges on the other side purified. This leaves the impurities behind and rinses them down a waste drain. Learn more…
Do water purification systems that use reverse osmosis remove minerals that are needed for good health?
Reverse osmosis does not remove minerals vital for good health.
Crescent Hills’ water purification system can remove over 90% of the fluoride in the water. Fluoride occurs naturally in both the earth and water, and is often artificially added to municipal supplies to help prevent tooth decay. The long-term effects of fluoridation of public water, however, is still unknown. Recent studies indicate that it may not be as healthful as originally thought, and has little benefit for teeth after childhood. Consider, too, that humans only consume about 2% of total fluoridated water. Further, there are more prudent alternatives to fluoridating an entire water supply, such as the application of fluoride tablets and vitamins that may provide a safer, more precise dose to your children.
The filters need to be replaced every 12 months. Your Crescent Hills representative can recommend the optimal change-out period based on your usage. We also suggest changing the storage tank air charge when we sanitize your system, which we do at no cost to you.
Can the Crescent Hills under-the-counter systems be connected to ice makers, refrigerator water dispensers and instant hot water dispensers? What kind of maintenance is required for those??
Most definitely, provided a water line is run from under the sink to the refrigerator. The tubing used should preferably be plastic. Existing copper tubing is often corroded and scaled from tap water and the purified water may dislodge this buildup and create problems in the ice maker. We recommend copper tubing not be used unless absolutely necessary. We can supply a special ice maker hookup kit that includes all the tubing and fittings required for the typical ice maker and/or refrigerator water dispenser connections.
What happens to all the organic and inorganic impurities removed by the Crescent Hills water purification system?
They are automatically rinsed from the membrane surface and washed down the drain. Unlike filters that trap impurities, the membrane used in the Crescent Hills drinking water system is self-cleaning. As water flows across the membrane, it becomes divided into two streams. The production stream is the purified water that is forced through the membrane by diffusion. The impurities are left behind. The concentrate stream serves as a rinse that carries those impurities off the membrane surface and into a drain. As a result, accumulation of impurities on the membrane is slow, keeping it clean and effective over time.
Crescent Hills offers free consultations for your home drinking water needs. A reverse osmosis system generally sells for $680.00. Our systems are also available to rent.
The water in my area tastes chlorinated when it comes out of the tap. What type of filtration system will help the most with removing the chlorine taste?
Reverse osmosis and carbon filtration.
My husband and I are looking for a water filtration system that will suit our apartment. Not sure how long will be here but also need something that is portable and that we will not be spending thousands of dollars on. Please help.
Reverse Osmosis systems are easily moved from one location to another.
I have a refrigerator that only has an inline filter instead of the additional (and much desired) second filter in the fridge. We have used the sink faucet one for awhile but it's so expensive, has to be changed a lot, and is always in the way when I'm doing dishes. Would you recommend getting an undersink filtration system or buying something like Culligan delivered already filtered water?
We recommend an under the counter reverse osmosis system. The filter will need to be changed annually.
