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.

Your Guide to Choosing the Right Pool Filtration System

August 19, 2024
Maintaining a pristine pool means you've got to have a pool filtration system that works hard—so you don’t have to. Whether you're dealing with a faulty system, thinking about upgrading, or simply trying to plan ahead, you're in the right place. We'll break down the three most common pool filtration systems to help you find a unit that fits your budget and needs. Why You Need a Pool Filter While the filtration process varies depending on the type of filter you choose, they all serve the same purpose—trapping contaminants and debris. This is essential for maintaining a safe swimming environment . A well-functioning pool filtration system : Captures visible dirt, debris, and bugs that fall into the pool Traps microscopic bacteria and algae spores—contaminants you cannot see with the naked eye Improves water clarity Circulates water, which helps with chemical distribution and even cleaning Prolongs the lifespan of equipment by preventing clogs and mineral buildup Types of Pool Filtration Systems Sand Filters Many homeowners choose sand pool filtration systems because they are simple, efficient, and affordable. These filters use a bed of specially graded sand inside a large tank. When water passes into the tank and through the sand, it traps debris and particles while allowing clean water to pass through. Most sand filters are capable of trapping 20-40 micron-sized particles. To put that into perspective, consider that: A human hair is roughly 50-70 microns in diameter The human eye can spot particles that are about 40 microns This is a long way of saying that a sand filter can remove most dust particles and pollen. However, it won’t filter very fine dust, bacteria, or viruses. This is, of course, why we use pool chemicals or automation systems to fill in the gap. Pool Cartridge Filters These units use a cylindrical cartridge made of pleated, paper-like material inside a tank. Here's how they work: Water flows through the cartridge The pleats trap dirt and debris Clean water is sent back to the pool No backwashing required! Most cartridge filters are capable of filtering 10-20 micron-sized particles (more than sand filters). You should know that you must clear your cartridge filter regularly to maintain efficiency. While not difficult, this process is slightly more hands-on than backwashing a sand filter. Diatomaceous Earth Filters (DE) Diatomaceous Earth (DE) filters are a highly effective pool filtration system that uses a fine powder made from crushed fossilized algae (diatoms). These units work by coating a set of filter grids inside a tank with the DE powder. As pool water flows through the tank, it passes through this DE coating, which acts as an extremely fine sieve. Two important facts about DE pool filters: They can filter contaminants and particles as small as 2-5 microns (much smaller than what sand or cartridge filters can). They require more maintenance than other filters. After every backwash, you must add power to recoat the grids. The tradeoff is that you achieve exceptionally clean pool water.

How Often Should You Replace Water Filters in a Water Purification System?

June 5, 2024
Whether for drinking, cooking, bathing, or any other residential need, contaminant-free water is essential! Water purification systems are excellent ways to protect the water that flows through your home, but they need regular maintenance to function effectively. Replacing filters is crucial to a maintenance plan, but how do you know when to change water filters? Is there a water replacement schedule you should follow? We'll answer these questions here! Why Filters Need Replacing The filter in your water purification system plays a pivotal role in delivering clean water. Filters trap bacteria, particles, and other contaminants, stopping them before they reach your taps. Over time, filters become clogged and get less effective, compromising your water quality. Water purification system maintenance is essential to keep water contaminant-free and protect the purification system's lifespan and effectiveness. Filters Factors That Affect Replacement Frequency Generally, most manufacturers recommend a water filter replacement schedule every 6 to 12 months. How often you need to change your water filters depends on several factors, including: The Type of Filtration System You Have Some high-tech systems require adherence to a stricter maintenance schedule to run efficiently. Familiarize yourself with your setup and the manufacturer's guidelines for maintaining the unit. Your Household's Water Usage Does anyone in your household enjoy long showers? Do you spend a lot of time washing dishes? Is the tap constantly being turned on for a glass of water? The higher your water usage, the more quickly filters get clogged, as water frequently flows through them. If you have high water usage, you may need to replace your filters every six months or sooner! The Quality of Your Water Source The initial quality of the water affects a replacement schedule as well. The cleaner the water is to start, the less work the filter has to do, helping it have a longer lifespan. The more contaminated the initial water, like well water, the more often you'll need to swap filters out for clean ones. Signs It's Time for a Replacement Some systems have built-in indicators that signal when to replace a filter, but not all! If your system doesn't have such an indicator, signs that your system is due for a fresh filter include changes in: Clarity Taste Odor All of these indicate that a filter is no longer effectively removing impurities. Replacement Options To protect the lifespan of your water purification system, it's important to choose replacement filters made specifically for your setup. If there are no manufacturer recommendations, choose a high-quality one compatible with your system. Generic, cheap filters typically don't have the filtration capabilities or longevity as those designed for use with your water purifier.

What Is Reverse Osmosis?

May 30, 2024
Do you spend more time cleaning your pool than swimming in it? Are you tired of calcium buildup, murky water, and endless chemical treatments? Many pool cleaning companies will tell you to drain your pool and start fresh in situations like this. However, experience has shown us that this is the wrong approach. Over the last decade, we’ve saved thousands of gallons of water using our Puripool™ Reverse Osmosis system. It’s cheaper, faster, and more efficient than pool draining. Plus, it preserves 85% of your existing pool water. If you’re new to the process, keep reading. We’ll tell you how it works and why it is an effective solution. Why Reverse Osmosis? We think reverse osmosis is our industry’s “worst-kept” secret. Although this technology has been around for decades, pool cleaning companies have been sluggish in adopting it—either because they don’t know about it or are misinformed about its effectiveness That is unfortunate because reverse osmosis is incredibly effective in revitalizing perfectly usable water by eliminating calcium and toxins like dirt, debris, bacteria, and heavy metals. Here’s how the process works. How Does Reverse Osmosis Work? Reverse osmosis purifies water using a semi-permeable membrane that dissolves solids and removes contaminants. The process begins by pressurizing the contaminated water and forcing it through the membrane, which traps pollutants while allowing clean water to pass through the other side. Let’s break that process down in simple language by showing you how we work. Arrival We arrive with a mobile filtration system that is entirely self-contained. We make great efforts to minimize disruption, so we do not need to tap into your power supply. You can even continue swimming while we complete the process. Pre-Filtration To start, we extend two hoses from our trailer into your pool. One hose pulls water from your pool to a pre-filter that removes contaminants before reaching the reverse osmosis membrane. The other hose returns clean water back into your pool. Pressurize and Treat Once filtered, we pressurize the water and guide it through the reverse osmosis membrane. This membrane has tiny pores that trap dissolved solids and contaminants while allowing clean water to pass through. Reintroduction Finally, the clean water is returned to the pool through the second hose. Why Choose Reverse Osmosis? It’s faster and more efficient : Our system can filter up to 40,000 gallons of water daily. On average, the process takes between 12-16 hours for the average residential pool Reduces chemical dependency : Fewer dissolved solids and contaminants means money saved on expensive pool chemicals Protects equipment : Reverse osmosis reduces calcium and scale buildup, protecting pool surfaces and equipment while reducing maintenance Eliminates contaminants : Our process removes bacteria, viruses, pesticides, and other contaminants you cannot see with the naked eye Increases clarity : Once treated, your once-murky water will be crisp, clear, and inviting Saves money : In addition to saving the money you would have spent draining your pool, you can also expect to spend less on cleaning services, chemicals, and equipment repair and replacement Crystal Clear Solutions For Common Pool Problems Are you tired of murky water, high chemical costs, and endless maintenance? We can help. Whether you need to revitalize your pool water, set up an automation system, or need help with maintenance or installation, we offer a comprehensive line of pool and plumbing services .

Frequently Asked Questions

  • How does the Puripool™ Process work?

    Our mobile filtration trailer utilizes reverse osmosis (RO) to reduce:


    Calcium hardness

    Total dissolved solids (TDS)

    Salts

    Phosphates

    Cyanuric Acid (CYA)

    Waterborne diseases

    And other contaminants from the swimming pool

    Our trailer is completely self-contained and runs on its own power. Two hoses extend from the trailer—one connected to a pump that draws water from your swimming pool into the mobile filtration trailer. We use a second hose to return the treated water to your pool. 


    The water undergoes pre-treatment before contacting the reverse osmosis membranes, ensuring pure, clean water returns to the swimming pool. We estimate how long the process will take by measuring the total dissolved solids (TDS). This tells us how long it will take to reduce contaminants and calcium levels to lower levels than your city offers.


    It’s worth mentioning that there is no downtime during the process and the interior finish of the swimming pool is never exposed.

  • How long does the process take?

    Currently, we can transform 40,000 gallons of water a day into safe, clean drinking water! Obviously, the size of your pool determines how long it will take based on this level. However, most residential swimming pools will take between 12 and 16 hours to complete, and commercial pools take longer.

  • Is the process safe?

    Absolutely! In fact, you can actually swim in the pool during the filtration process! There are no power cords or electricity in or near your pool, nor are they lying around for someone to trip on.


    An inch-and-a-half hose with a Virginia Graeme Baker Act (VGBA) compliant fitting is placed in one end of the pool to draw the water back to the trailer for treatment, and another inch-and-a-half hose returns the clean (drinkable!) water back to your pool. That’s it!


    We are 100% self-contained and do not need to inconvenience you with electricity, extension cords, or an outlet.


    All we need from you is a freshwater supply to replenish the small amount of water lost during the process—approximately 15-20%.

  • My pool water is cloudy or has a green/yellow color. Will the Puripool™ Process help?

    Even though the Puripool™ Process can transform contaminated pool water to drinking water standards, we are not a pool filtering/maintenance company.


    Your pool equipment or pool service company must clear any suspended solids and algae from your pool before we begin work. Our service is strictly limited to the chemical purification of your pool and the removal of total dissolved solids (TDS), viruses, bacteria, allergens, and waterborne diseases that your pool equipment cannot remove.


    In short, your pool water must be clear, non-turbid, and algae-free before we begin the Puripool™ Process.

  • How can I tell if I have hard water in my pool?

    If you spot scaling, chances are you have hard water—even if it isn’t visible to the naked eye.


    Your best chance of identifying hard water is if you turn on the lights for your swimming pool at night. Typically, you can see these scaled particles floating around your pool at night! If you haven’t changed the water in your swimming pool in two or more years, it’s there! Trust us.
