Mobile Filtration For Residential and Commercial Applications

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 (CYA)
  • Total Dissolved Solids (TDS)
  • Borates
  • Salt
  • Iron
  • Copper
  • Magnesium
  • Algaecides
  • Sequestering Agents
  • Phosphates
  • Bacteria and Viruses
