Chlorine Pool & Non-Chlorine Pool Chemistry

Chlorine is used in pools to maintain it bacteria and algae free; it is a sanitizer (disinfectant), oxidizer, algicide and it can hold a residual value in the water.
Without Chlorine (or Bromine), there is significant risk for bacteria to grow in the water and potentially make you sick.

With the Aqua Biolight PhotonTransmitter installed as Peripheral Hardware the initial amount of Chlorine (Bromine) on your pool system can be significantly reduced. Together with the back-up of Oxygen Compounds, soft UltraSonic, and/or UV device you can drastically further reduce the total amount of chlorine that you need. Up to an 80% reduction of the amount of chlorine that you use in a year is within reach, and a much better idea than trying to run a Public Pool completely chlorine free.

You must control of course pH and Alkalinity, respectively Hardness.
You can do this with all kind of compounds to push pH up or pH down
and stabilize Total Alkalinity within the preferred limits of 80-120 ppm.

The most favourable way to do this is with multi-non-chlorine products, 10% NaHCO3 solution (soft pH up and limited to 8.4, also prevents black Algae growth),  10% NaHSO4 solution (pH down <5.0) or alternatively CO2 (pH down and limited to 6.7) or Cyanuric Acid in case of Chlorine Pools) and Borax (neutral, Stabilizer, also prevents blue and green Algae growth) add 50ppm to user`s need. Borates stop the algae cell from both producing food (photosynthesis) and then eating it (metabolism).

The limitation of systems such as UV and UltraSonic is that they do not hold a residual value in the water. Chlorine is added to a minimal extend on Public Pools, also to comply with the Regulations. You can rely on the Peripheral Equipment to do the heavy lifting, so to speak, and let the chlorine kill anything that is free floating in the water.

Aqua Biolight is an effective way to eliminate bacteria in swimming pool water and can be used on almost every type of pool and adapts easily to existing systems. It does however not eliminate algae and/or prevent algae growth. The remaining free chlorine is taking care of that. This amount (approx. 40% of the common amount, i.e. 0,8 ppm instead of 1,3 to 1,5 ppm), however might be needed to back-up the sanitizing effect of Aqua Biolight.

Pool Filter filled with AFM (activated Filter Medium), a pure green glass with a mesoporous structure and a large catalyc surface ensures a 30% better filtration compared to sand and makes your filter bio-resistant, self-disinfecting and self-cleaning, thereby saving on anti-algae, Chlorine, water consumption and energy.
Addionally, a UV Generator, and/or a soft-UltraSonic device can be installed, which adds a frequency energy to the recycle pool water, thereby disturbing the algae growth and further reducing the amount of Chlorine to be added to 20% or less.


The advantages of the safe, green Aqua Biolight technology
and additional Peripheral Hardware:

Can reduce the use of chlorine and other chemicals by up to 80% and more.
Is effective against all micro-organisms except for Algae (Algae is life),
greatly improves the water quality and creates a comfortable environment for bathing.
No red eyes or skin irritation, no problems for people with asthma or allergies.
It reduces the chance of Chloramines build-up on the water surface to nihil.
It reduces the use of supporting chemicals for water treatment (pH and Alkalinity Stabilization), like cyanuric acid (on Public Pools).

The Crystal clear sustainable Aqua Biolight structured, energized, healthy, healing, living and vital water gives health, beauty and enjoyment of life. Fully automatic and cannot be overdosed and results in significant lower chemical, energy and maintenance costs.

Whether the public pools are equipped with Aqua Biolight, AFM filled Pool Filter, Oxygen generator or -compounds, back-up UV Generator and/or an UltraSonic device, ideally it needs a return that goes to the bottom of the deep end of the pool as this will allow the longest amount of contact time with the water to be effective.

One can easily operate Residential-Private Pools (low occupancy) without Chlorine, instead with NaHCO3, NaHSO4, CO2 (alternatively), Borax, Oxygen coumpounds, thorough pH and Alkalinity Control, Aqua Biolight, AFM, eventually UV back-up and soft UltraSonic.

Please read also: “One CDC study found that more than 10% of routine inspections of public pools, hot tubs/spas, and water playgrounds (for example, at hotels/motels and waterparks) led to immediate closure because of serious violations, such as improper chlorine or bromine levels. Swimmers can check for adequate free chlorine (1–3 parts per million or ppm in pools/water playgrounds and 3–10 ppm in hot tubs/spas) or bromine (3–8 ppm in pools/water playgrounds and 4–8 ppm in hot tubs/spas) and pH (7.2–7.8 in all types of water) levels.
