Most individuals are very aware of what Reverse Osmosis (RO) is used for. Typically, the most common application is for drinking water and this application is usually installed under the sink in your home. According to Wikipedia, “reverse osmosis is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking 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.” Quite simply, it is a process that removes calcium, salts, waterborne diseases, phosphates and so much more to provide you with the best quality of water!

Recently, this form of filtration has also been applied to swimming pools because of water quality issues, drought conditions and pool safety. In many areas of the country, including Dallas, the water coming out of our tap is loaded with calcium and other hardness minerals. Depending on where you live in Texas and even Oklahoma the water coming out of the tap is at a minimum of 300 parts per million (ppm). The most optimal range for swimming pools is between 200 and 400 ppm but as water evaporates those hardness minerals remain in solution and gradually increase over time. As this happens, calcium will deposit on filtration equipment, stain the water tile line, stain the liner and ruin water features. When this happens (typically after 2-3 years) homeowners and commercial property swimming pool owners will need to change out the water in the pool. If you choose to do a typical drain and refill, this process can take up to 2-3 days, the chance of ruining your liner increases and the water is moderately hard from the tap. Whereas, Weber Pools offers RO Mobile Filtration using the Puripool Process, which comes to your house or commercial property.


This form of filtration lowers calcium hardness, total dissolved solids, phosphates, salts, waterborne diseases, cyanuric acid and so much more without draining the swimming pool. This takes the risk of ruining your liner out of the question, it puts drinking quality water back in your swimming pool, it conserves 85% of the existing water in the pool and you can swim in the pool while the process is being done. The form of filtration is completely safe for your swimming pool, can be performed all year round and when it is performed every couple of years it can prolong the lifespan of your swimming pool!
