Balancing Water Chemistry2018-10-05T11:32:52+00:00



The maintenance of swimming pool water is multifaceted in the number of factors that must be controlled. More often than not, pool maintenance is simply thought of as needing to periodically add a sanitizer, adjust the pH and run the filter. In reality, swimming pool maintenance is much more than that.

pH, the measure of hydrogen ions in water, is the most important dynamic of water chemistry. The pH of water, captured in a confined space at a natural water temperature (56 – 80°F), unaltered by human interaction, rises predictably. An independent study of pools in Arizona, Florida and Brazil show a predictable increase of pH over a two-week period from an initial pH of 7.5 to pH of 8.5. This increase in pH is attributed to the Earth’s rotation.

The pool industry recommends maintaining pH between 7.2 and 7.8. This range is best for optimal effectiveness of any chemicals added to the pool to manage the water. However, every chemical has its own pH and affects the overall pH of a body of water. This makes it complex, if not impossible, to maintain pH in a precise range more rigid than that prescribed by the industry.

A mathematical formula, created from data taken of eleven pools over a course of two years, reliably and accurately predicts the pH of confined bodies of water. This model, which accounts for the effect of the Earth’s rotation, can precisely calculate pH more accurately than any current measurement technology available.

The Septor 7 Water Management System balances pH by taking advantage of the amphoteric nature of water. Hydrogen ions produced within the cartridge during the electrolysis of muriatic acid may be positively or negatively charged, making them attracted to the respectively oppositely charged polar end of water molecules. These ions attach to circulating water molecules, forming a mist, comprised of hydronium and hydroxide ions and water molecules, that streams into the filtration system. By controlling the quantity and pH of the hydrogen ions produced, the Septor 7 can be customized to balance pH to any desired value for a wide variety of applications.

The Septor 7 cartridge, also referred to as the ion generator assembly, is engineered to produce ions of a specific pH, shape, and quantity. These parameters are developed from the mathematical model previously mentioned to counter the effect of the Earth’s rotation. The rate at which ions are produced and integrated with the water allows for consistent pump system parameters to be used. Precise water pH can be controlled by minutes, hours, or days, using custom-made ions.

All portable, none portable, pool, spa, water system in the world require continuous monitoring and addition of chemicals to adjust pH. The benefit of the Septor 7 technology is that the water will be precisely balanced without the addition of non-native chemicals and requires no human interaction/ participation to the water. Because the ion is not a particle and has no hardness, the water is clearer, safer, and more pleasant to use for swimming or drinking.

Algae and organic particles are present in all water to some degree. Wind, dirt, rain, and people bring a relentless assault of algae to the water. Algae spores reproduce quickly and, given the right conditions, are capable of doubling their numbers within a few hours. Although these organisms are not visible to the naked eye, as they increase their numbers (and reach a saturation point), they make a visual impact on your pool. Water may first appear dull and lifeless—not shiny—in the initial stages of a bloom. Depending on water conditions, this can rapidly turn into a discoloration in the water from their pigments and ultimately lead to colonies taking root on pool surfaces.

Chemicals such as chlorine kill algae by disintegrating the outer walls of their cells, reacting with the material inside thereby rendering the organism no longer able to multiply. Disinfection with chlorine is not instantaneous and efficacy is dependent on concentration and contact time. Chlorine only works in balanced water, yet even in optimum conditions, chemicals like chlorine are only 20-30% effective due to side reactions like the formation of chloramines and other byproducts. When pH and alkalinity are out of normal range, toxic chemicals won’t poison the algae.

In contrast, the Septor 7 ion controls algae on multiple levels:

  • By regulating pH within tight parameters without disrupting alkalinity, water is perfectly balanced every minute of every day. Proper water pH and alkalinity levels reduce the potential for algae growth and the stability of these two properties by the Septor 7 precludes the opportunity for algae to have the right conditions to bloom.
  •  Ion distribution is integral with the water molecules, not dependent on the presence of stabilizer. The ubiquitous presence of the Septor 7 ions and the absence of side reactions maintains efficacy in controlling algae 3-4 times greater than chemical sanitizers.
  • Ions in the water create an uninhabitable environment for algae to grow, ravaging the organism from the inside out. Camouflaged as oxygen, algae feast upon it and spontaneously explode, extinguishing any potential to bloom.

The Septor 7 Water Management System is engineered for versatility, portability and convenience. No other invention in the world manages the complexity of balancing all three legs of water chemistry simultaneously without introducing chemicals to the water. Septor 7 technology is truly remarkable in its ability to convert any freshwater source into pure drinking water. The utility of such extraordinary technology has applications for household, environmental, agriculture, industrial and recreational purposes.

Total Alkalinity (TA), the measure of alkaline minerals dissolved in water, helps to buffer water and resist dramatic fluctuations in pH. Water, in the absence of chemical intervention, has alkalinity properties of 40–60 ppm and can be perceived in the physical attributes of water quality—color, clarity, shimmer. Cloudy, dull, lifeless, murky water are indicators that alkalinity is outside of this natural range. In order to prevent pH bounce and maintain chemical effectiveness, the recommended level for alkalinity of water in a confined space is 80-120 ppm.

Managing alkalinity is twice as difficult, compared to pH, when water is chemically managed. Alkalinity is very sensitive to the addition of chemicals used to control other parameters such as pH, phosphates, sanitizer, hardness and stabilizer levels; bather load has an indirect impact on alkalinity due to the production of by-products like chloramines.

pH and alkalinity are intertwined; it is impossible to chemically adjust pH or alkalinity without altering the other. Alkalinity trends in the same direction as pH (low pH/lower alkalinity; high pH/elevated alkalinity) but because pH is a logarithmic value and total alkalinity is linear, they will not be lowered or raised at the same rate. The addition of acid to lower pH induces alkalinity to drop and the constant addition of acid makes it much more likely that alkalinity will fall below the normal range over time. Conversely raising alkalinity can only be accomplished with the addition of carbonates and more dramatically affects pH. It is easy to see how the ‘yoyo effect”, constantly adding one chemical that must be countered by another, can become frustrating in balancing water chemistry.

There has not been a practical way to raise only the pH without affecting TA—until the HYDROVortX technology in the Septor 7 Water Management System. Because the Septor 7 balances pH without chemicals, alkalinity is not altered. Once the alkalinity is balanced in the recommended range of 80 to 100 ppm, it is maintained within those parameters with no adjustments necessary. Septor7 manages this with the pH balanced ion that attaches to the oxygen in the water and results in no net effect on alkalinity properties.
