If you swim in a lot of commercial swimming pools, you probably have noticed that the pool water tastes salty. This isn’t uncommon but why does this happen? Simply put, most commercial swimming pools inject liquid chlorine as a disinfectant into the pool and that will cause the salt levels to rise. When dealing with residential swimming pools the amount they use can’t be compared to a large commercial swimming pool with lots of bathers that’s why you might notice a salty taste when swimming in the water. As a bather, this can make your swim experience far less than desirable so what should you do?

For most swimming pool owners in the Greater Phoenix area, changing out the water every two years is extremely important to keep your Calcium Hardness (CH) levels low. Since our fill water is loaded with it we recommend changing out the water to prevent calcium from scaling the water tile line, interior finish, filtration equipment, salt chlorinator, spillways and decorative water features. As for commercial swimming pools with a higher number of bathers changing out the water is key to keeping salt levels down along with Cyanuric Acid (CYA) and TDS levels. Commercial swimming pools are monitored by state regulations and their water chemistry must be within normal limits or they can be shut down. So what if it’s in the middle of summer where it’s too dangerous to drain a pool or if it is during your busy months where having a pool out of commission will cost you money? What should you do?

Well, if you want to have the best quality of water in your swimming pool that your bathers can enjoy, your best option would be to use Reverse Osmosis (RO) filtration. This is a service that is available to those with swimming pools in the Greater Phoenix area and it will lower the salt levels along with Calcium Hardness and Total Dissolved Solids. Since RO filtration can filter down to an extremely low micron level is has the ability to lower salt and TDS levels which are monitored by the state for compliance reasons. Recently, DC Ranch Village Health Club & Spa chose to have us recycle their 70,000-gallon lap pool because it had a salty taste and the swimmers were very aware of this. Upon arriving at the club we measured the salt content to be at 4833 parts per million (ppm) which would be on the high end for most saltwater pools!

After filtering this swimming pool for two days, we were able to lower the salt content to 1470ppm. We were also informed by the General Manager on the property that one swimmer stated, “they could really feel a difference on his skin and the water looked great!” If you’re a commercial swimming pool owner, keeping your bathers happy and making sure your chemistry levels are in compliance should be your number one concern along with potential waterborne diseases. Our mobile filtration system can help with all of this and so much more! If you should have any questions, please contact us today!
