In the commercial industry, proper pool maintenance requires a drain and refill approximately every 6-12 months, depending on usage and/or TDS (total dissolved solids) levels higher than 2,000 parts per million. This practice produces wasted water as well as wasted chemicals. Commercial properties will benefit from our trailer mounted, mobile filtration unit, or larger properties may opt to have you install full-time inline units, allowing them to never drain their pools again, except for re-plastering! Either way, large amounts of water will be conserved.

Residential pool water needs to be removed and replaced every 2 years, depending on starting TDS and Calcium Hardness levels. In less than a day, the mobile filtration unit will not only remove the hard water minerals from the pool, allowing your customers to use fewer chemicals but will also retain nearly 85% of the existing water. Your customers will be left with a swimming pool that is as clean as bottled drinking water!

Some of the benefits of using the Puripool Process include:

  • Water Conservation – Saving a precious, and limited, resource
  • Less Chemical Demand and greater equipment reliability
    (less hard water build-up)
  • No Down Time – Pool can remain open during treatment
  • Plaster is not exposed or compromised
  • Soft-water swimming experience

Our Puripool Process lowers or removes:

  • Calcium Hardness
  • Cyanuric Acid
  • Borates
  • Salt
  • Iron
  • Copper
  • Magnesium
  • Algaecides
  • Sequestering Agents
  • Phosphates
  • Bacteria and Viruses
  • Total Dissolved Solids
