What does Reverse Osmosis Remove from Pool Water?
As you know, over time, calcium levels in your pool accumulate, and the water becomes "harder".
Reverse Osmosis is capable of removing up to 99%+ of the dissolved salts (ions), particles, colloids, organics, bacteria and pyrogens from the feed water (although a reverse osmosis should not be relied upon to remove 100% of bacteria and viruses). An reverse osmosis membrane rejects contaminants based on their size and charge. Any contaminant that has a molecular weight greater than 200 is likely rejected by a properly running RO system (for comparison a water molecule has a MW of 18). Likewise, the greater the ionic charge of the contaminant, the more likely it will be unable to pass through the RO membrane.
Reverse Osmosis is very effective in treating brackish, surface and ground water for both large and small flows applications. Some examples of industries that use RO water include pharmaceutical, boiler feed water, food and beverage, metal finishing and semiconductor manufacturing to name a few.
Reverse Osmosis Water Filter Systems are a valid option for use in pools and spas. Municipal water contains high levels of calcium and other minerals that cause hardness in water. A small amount of calcium is recommended in pools (150-250 ppm), but once the water in the pool begins to evaporate, the levels of calcium spike dramatically. This causes buildup on the liner, the water line against the tile and in the pool equipment. Calcium becomes very troublesome for owners of swimming pools because it ruins the decorative tile and also causes water chemistry issues.
Chlorine is an important chemical for pools, but calcium absorbs the much needed chlorine. This can force a pool to go out of service. The first instinct is to add more chemicals to balance out this problem, even though doing so can cause more problems and create more work for the homeowner, but using a reverse osmosis water filter system is a much easier and eco-friendly alternative.
Instead of draining the entire pool and then fill it up with the same municipal water containing high levels of calcium, the more viable option is to recycle the pool water, filtering out all the contaminants using a reverse osmosis water filter system. With this method, you can conserve up to 90% of the water that was in the pool.
Using a reverse osmosis water filter system to filter out harsh chemicals such as calcium, salts and other hardness minerals will expand the life and maintenance of the swimming pool equipment. Along with the reverse osmosis membrane, a reverse osmosis water filter is used to help filter out unwanted chemicals. The reverse osmosis water filter helps filter out chemicals such as calcium, cyanuric acid, salts and alkalinity levels in the pool.
