The simplest answer to this question is yes! It might be a relatively new concept in the swimming pool industry but as far as water purification goes, it has been around for a very long time. Whether it is seawater, tap water, brackish or swimming pool water it can be purified but the system in which you do it will differ. As far a swimming pools go, the water can be purified by way of Reverse Osmosis (RO) but we want to explain how this is different from your under the sink RO system. If you’re not familiar with RO, according to Wikipedia, “it is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvents allowed to pass to the other side. To be “selective”, this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules) to pass freely.” If you are familiar with RO in your house, those are extremely inefficient because for every 1 gallon of water produced, it wastes 5-6 gallons. So you might be thinking, how is this good for the swimming pool industry when you have on average 20,000 gallons of water and are experiencing drought conditions? Well, we hope this blog posts explains why it can be done as well as why it is your best solution.
Water loss with RO is directly dependent upon water pressure. The higher the pressure forcing water through the membranes the less water loss. This should help explain why normal tap water that runs through an RO membrane loses so much water whereas with more sophisticated systems you can achieve far less water loss. We recently purchased a mobile filtration system that will allow us to not only recycle swimming pool water but also retain 85% of the water in the swimming pool. The unit itself will travel to your home or commercial property where two hoses will be used in the swimming pool. One will be your intake hose and the other will be for the purified water to be introduced back into the pool. The intake hose will take water from your pool and travel through a series of booster pumps that will force the water to enter the membranes around 200psi. This is how we can retain so much water! As the water hits the RO membranes it will lower the following issues that most swimming pool owners will face and why swimming pool professionals will tell you that it’s time to change out the water in your pool…
- Calcium hardness
- Total Dissolved Solids
- Cyanuric acid
- Waterborne diseases
- And so much more…
As the water enters back into the swimming pool at a drinkable state, we are giving you a much better product than a typical drain and refill because the water in the LA area is about 300 parts per million calcium hardness and not drinkable. Our guarantee to you is that we will give you better water than tap, we will purify your swimming pool in typically less than a day (residential only), we will not expose the surface of your swimming pool and you can actually swim in the pool while the process is being performed. If you are curious as to how this mobile filtration process can help you, give us a call today!
