Swimming Pools, Fountains & Lakes


Water quality maintenance is one of the greatest daily challenges in swimming pool operations. Chlorine can have damaging effects on the human body, corrode facilities and cause-related maintenance problems and overall increase utility/water costs. Data obtained from numerous public water facilities and related industries shows the economical and health benefits of using water treated with our proprietary system in such operations. Pursanova also offers excellent product maintenance services, while still maintaining affordable prices. We’ve received many enthusiastic comments from pool patrons, coaches and staff such as, “The water is just so much cleaner,”“Our patrons enjoy the clean, refreshing water in our pools,” and, “With the Pursanova PursaLex™ we’ve definitely seen an improvement with chlorine related problems.”

Common Public Swimming Pools Problems

Health Issues:

Chlorine can cause eye irritation and red-eyes as well as allergic reactions in some individuals, especially in the sinuses or even on contact with skin. Swimming in chlorinated pools can also aggravate throat and breathing conditions and damage or bleach hair.

Polluted Water:

Polluted water can cause a foul odor and make the water cloudy and opaque. This, in turn, means that more hypochlorous acid and potassium permanganate will need to be used and filtration tanks will require more back-washing, resulting in an increase in water usage.

Facility Degradation:

Pipes, infrastructure, the pool and the plumbing can become corroded with oily residues becoming more difficult to remove. Additionally, mold can grow on walls and ceilings.

Other Problems:

Water temperatures can become more susceptible to changes in outside temperatures, resulting in fluctuating patronage rates. It can also have an effect on the overall health and well-being of employees.

The Pursanova PursaLex™ System Leads to Improved Filtration and Decreased Chemical Usage

Electromagnetic measurements have shown that PursaLex ceramics constantly radiate infrared light in the range of 1 to 20 microns. When these ceramics come in contact with water, the water is activated, becoming more soluble and absorbable. The same effect can then be conferred from the water to any living organism upon contact. Analysis indicates that surface tension is actually decreased in PursaLex water. Further, activated water has been shown to evaporate 70% slower than normal water at room temperature. Pursanova ceramic ores have been shown to be very safe, and are made from natural minerals that undergo a sintering process at 1300C°, and their polished protective coating ensures continued optimal performance. Pursanova ceramics are certified by the Japanese Health, Labor and Welfare Ministry under the Japanese Food Hygiene Law (Clause 370).

Benefits of the PursaLex™ System

Reduction in Chlorine Related Problems

  • Significant reduction in release of chlorine gas from chlorinated water
  • Relief from itchy, blood-shot or painful eyes. Improved skin condition.
  • Relief from throat pain caused by accidental ingestion of water
  • Relief from sinus and allergic reactions
  • Reduced damage and bleaching to hair

Easier Maintenance

  • Dramatic improvement in filtration system condition
  • Reduction in use of hypochlorous acid, potassium permanganate, and other chemicals
  • Improved clarity of water, flocculants (clarifying agents) no longer necessary
  • Improvement in water’s ability to retain heat
  • Prevents water temperature to drop
  • Significant reduction of chlorine and other swimming pool odors
  • No more chlorine odor as well as swimming pool odor.
  • Frequency of filtration backwashing necessary dramatically decreased (up to 80% less)

Prevents Facility Corrosion

  • Decreased condensation
  • Less mold on ceilings and walls
  • Reduced sludge build-up on pool walls
  • Improvement in rusting of pipes

Additional Considerations

The system also helps maintain temperatures in swimming pools. In one example from a colder region, the swimming pool water temperature typically measured around 30C° at night. Then in the following morning, the temperature would usually drop by around one degree. After installing the Pursanova PursaLex™ System, the average drop in water temperature fell to 0.5C°. This feature has helped many pool facilities in cutting heating costs. Swimming coaches and pool staff have also noted fewer symptoms of cold exposure such as backaches, muscle stiffness, and joint pain. Some swimming pool facilities even reported that staff members were catching colds less frequently after installation of the Pursanova PursaLex™ System.

Heating Cost Savings

A decrease in 185 tons of water means a decrease in heating costs equivalent to the cost of heating 185 tons of water. PursaLex™ treated water also absorbs heat more readily, saving further on heating costs as well as time. Customers can potentially see savings of up to 30% in heating costs alone thanks to the temperature stabilizing effects of the PursaLex™ system.
