Pool Reverse Osmosis

Pool Reverse Osmosis Treatment

Millions of gallons of perfectly usable pool water are wasted every year. We’re on a mission to change that. Our Puripool™ Reverse Osmosis system revolutionizes pool maintenance, preserving 85% of water and eliminating pollutants, leaving you with crystal-clear water in just one day.

Cleaner, Faster, More Sustainable

We’re not making waves in our industry for nothing. We've reinvented traditional pool cleaning services that are time-consuming and wasteful. Using cutting-edge technology, we reduce calcium hardness, eliminate toxins, and revitalize your pool in just one day.

What is Reverse Osmosis?

Believe it or not, you may not be able to visually detect the need for reverse osmosis treatment in your pool water because the contaminants cannot be seen with the naked eye. However, several indirect indicators can help you identify when your pool needs reverse osmosis treatment:

  • Calcium Deposits: You may notice the presence of calcium deposits on the plaster or tile line in your pool.
  • Chemical Consumption: If you’re burning through a significant amount of pool chemicals to maintain water quality, it could be a sign of contamination.
  • Equipment Damage: Poor water quality can damage your pool’s light fixtures and equipment.

In such cases, our competitors may tell you to drain your pool and start fresh. That’s the wrong approach. Our treatment offers a cost-effective, low-labor alternative that revitalizes your water. 

Here’s a quick overview of how the process works. First, we pressurize pool water so it flows through a reverse osmosis membrane, which traps unwanted particles, including:

  • Total dissolved solids (TDS)
  • Dirt and dust
  • Lowers calcium hardness and minerals
  • Viruses
  • Heavy metals
  • Phosphates
  • Cyanuric acid (CYA)

Once the water passes through the membrane, we rechannel the treated water back into your pool, leaving it clear, clean, and contaminant-free. The best part? From start to finish, the process only takes a single day. 

Benefits of Reverse Osmosis Treatment

Reduces Costs

Save money on chemical expenses, conserve water, reduce unnecessary repair costs, and extend the life of your pool equipment—all while enjoying cleaner, safer water.

Increases Water Clarity

Our process improves water clarity and color, giving you better views, and an overall safer, cleaner, more sustainable swimming experience.

Less Maintenance

Spend more time swimming—not vacuuming. Reverse osmosis reduces time-consuming maintenance routines without introducing additional chemicals.

Softer Water 

Reverse osmosis also reduces hardness found in most tap water, eliminating the unsightly scaling you’ll find on your tile and filtration equipment.

Less Contaminants

Over time, pools accumulate dirt, debris, bacteria, heavy metals, and other toxins. Our process filters out these contaminants—even those you can’t see with the naked eye.

One-Day Process. Long-Term Savings

How We Work

We arrive with a mobile filtration trailer designed to clean your pool water on-site. Like everything we do, our trailer is self-sufficient and runs on its own power.

To begin the process, we connect two hoses to the trailer—one for extracting water from your pool and another for returning purified water. The pre-treatment process occurs before the water reaches the reverse osmosis membranes, ensuring only pure, clean water is returned to your pool.

Our system can handle up to 40,000 gallons in a single day, which means we complete most jobs in 12-16 hours. Commercial pools may take longer, depending on their size. Once we’re done, you’ll be left with a pool that’s clean, safe, and free from contaminants.
