When pool water develops high Total Dissolved Solids (TDS), calcium hardness, or cyanuric acid (CYA), draining and replacing the entire pool is not your only option.
Reverse osmosis is a filtration method that pushes water through a fine membrane, catching minerals and dissolved solids that regular filters miss. Applied to a swimming pool, this is known as reverse osmosis pool filtration, and it works without draining the pool first.
A reverse osmosis pool filtration system is set up as a mobile trailer that hooks into the pool with a hose. Pool water is drawn out, passed through the RO membrane, and returned cleaner than before. The leftover concentrate is sent to a drain, and a small amount of fresh water tops off what’s lost. At No Drainer, this is where we specialize — running the RO process on-site so pools stay filled and open throughout treatment.
The result is reverse osmosis water that’s noticeably softer, with lower calcium and dissolved solids than untreated pool water. Since the whole setup runs on its own power source, a small reverse osmosis plant like this can treat most residential pools in under a day, at any time of year, without pulling the pool out of service.
Reverse osmosis is a membrane-based filtration process that separates water from many dissolved substances. For swimming pools, RO filtration can be used to reduce Total Dissolved Solids (TDS), calcium hardness, cyanuric acid, salts, phosphates, and other substances that accumulate in pool water over time.
When water chemistry becomes increasingly difficult to manage, continually adding chemicals may not address the underlying buildup. Reverse osmosis for swimming pools provides an alternative by treating the water itself instead of automatically replacing the entire volume of pool water.
Total Dissolved Solids, or TDS, can increase as pool water is used, treated, and replenished over time. High TDS can make maintaining pool water more difficult and may affect the overall water condition. Mobile reverse osmosis filtration is designed to reduce TDS by removing many dissolved substances from the water being processed.
High calcium hardness can contribute to mineral buildup and calcium scale on pool tile and other surfaces. When calcium levels become difficult to manage, reverse osmosis can reduce calcium from the pool water as part of the purification process. This gives pool owners an alternative to relying solely on draining and replacing the water.
Cyanuric acid, commonly called CYA or pool stabilizer, can accumulate over time. When CYA becomes too high, maintaining appropriate pool chemistry can become more challenging. Reverse osmosis pool filtration can reduce CYA from the existing pool water, providing another option when a homeowner is told that draining is necessary because of high cyanuric acid.
Pool water can also accumulate salts, phosphates, and other substances over time. Mobile RO filtration can reduce a range of unwanted substances from the water being processed as part of the overall pool water purification process.
Our reverse osmosis equipment comes directly to your property.
High TDS, calcium, or CYA does not always mean your pool needs to be completely drained.
The process is designed to recover and reuse most of the existing pool water.
We provide pool water purification services in Phoenix, Scottsdale, Cave Creek, Fountain Hills, Tempe, and Glendale.
