      Utilizing Reverse Osmosis For Treating Green Pools

      One of the most popular questions we get asked at Pure Water Industries is if, “Reverse Osmosis filtration can clean up green pools?” The simple answer to this question is no. RO mixes with algae just as well as oil and water! We all know swimming pools get neglected or phosphates increase in the pool which can cause an algae bloom. In addition, with excessively high levels of Cyanuric Acid (CYA), it isn’t uncommon for swimming pools to turn green. However, there are a few things that are extremely important for us to discuss on how to tackle what is needed when this question is asked.

      First and foremost, algae grow in swimming pools because of the following reasons:

      • Lack of chlorine or other forms of sanitation
      • Improper filtration run times or dirty filters

      Depending on the time of year, you will need to make sure you have adequate amounts of chlorine in your pool (minimum 3 parts per million) and that your filter is running long enough. Both need to be higher in the summertime when the water is warm. Other factors that can cause a pool to turn green is if your CYA levels are high which will require you to have higher amounts of Free Chlorine to combat it or if your filters are dirty or your sand is old.

      Typically, if all those are working correctly, then your pool should be clear and blue. So, if this question is asked of you, please don’t filter their swimming pool if algae is present because it will plug up your membranes. It is instead warranted to support them by giving advice on how to clear it up first, then after that is complete and the water is clear, you can then come to the residential or commercial swimming pool and recycle the water using your Reverse Osmosis mobile filtration trailer.
