Quite simply, the best way to remove calcium from your swimming pool is by using Reverse Osmosis (RO) filtration. Most people are quite familiar with RO to provide drinking water and the small tanks that typically sit below your sink. Those tanks provide drinking water to homes and businesses but are quite inefficient when it comes to water conservation. Typically, for every one gallon of water, they waste 7-10 gallons. This is because these tanks run on normal water pressure and can’t provide the higher pressure needed to minimize water loss. Whereas, at Pool Water Recycling we use industrial size RO membranes on our mobile filtration trailer to save as much as 85% of the existing water in the swimming pool. The purpose of this blog post is to inform you how this is done.

If you own a swimming pool in Southern California, dealing with high calcium hardness, total dissolved solids (TDS), and cyanuric acid is pretty common. As swimming pool water evaporates the hardness minerals remain in solution and build up over time. After a couple years, you will notice scaling on the water tile line, the interior finish, your filtration equipment and any water features you might have. If you test your water or take a water sample into a pool store chances are the calcium hardness levels will be high and they will recommend draining your swimming pool to remove calcium hardness. The problem with that train of thought is the following:

  • We are in a drought and by draining your pool you will lose on average 20,000-gallons of water and another 20,000 just to fill it up.
  • Our fill water comes out the tap around 400 parts per million (ppm) which is already on the higher level of the minimums recommended for your pool.
  • It typically takes 2-3 days to do this
  • You could crack the interior finish of the swimming pool

Instead, our mobile filtration trailer comes to you and we recycle the water using RO filtration. We can lower calcium hardness, TDS, CYA, phosphates, salts and waterborne diseases without draining the pool. We can finish most residential swimming pools in less than a day, you can swim in the pool while it is being filtered and you can conserve on average 20,000 gallons of water in less than a day. Since the interior finish is never exposed it lowers the risk of damaging it and we put drinking quality water back in your swimming pool.

Reverse Osmosis is the best way to filter swimming pool water for many different reasons. If you are curious how you can get the best quality water for you and your family to swim in, contact us today.

Pool Water Recycling can also filter commercial swimming pools too. All jobs are bid based on gallons in the water. To learn more, call us today!
