Watermaid Ezy-300 Standard System
The best available system for reliability, simplicity and long life
More flexible system - Able to 'Super Chlorinate' if required due to increased pool use or Algae problem caused by incorrect filtration times or power supply interuption.
Always remember -Correct pH levels are still important even with a 'Watermaid' system
The benefits of Salt to Chlorine systems in swimming pools are:
1. The convenience and the constant delivery of pure chlorine-based sanitizer.
2. The reduction of irritating chloramines versus traditional chlorinating methods and the "softening" effect of electrolysis reducing dissolved alkali minerals in the water are also perceived as benefits.
3. For some people that have sensitivities to chlorine, these systems may be less offensive.
4. Salt water pools are cheaper to maintain throughout the year, since salt is significantly cheaper than the commercial chlorines
5. Control and Reduction of the chemicals used in the pool in particular Cyanuric Acid(added to every tablet), harmful to the pool structure and reduces the ability of the chlorine to work effectively - Maximum 75 ppm allowed in public pools in Spain
6. Remember that Salt Systems used in swimming pools are "Low Salt" compared to a "Seawater Pool" Salt Pool systems are between 2,000 and 6,000.
The Ocean is 35,000ppm (ppm = parts per million)
Maintaining the pool pH within the correct parameters 7.2~7.8
is not as simple as it may seem as those that check it regularly will know
As the pH rises with the addition of topping up the water or bathers entering the pool, chlorine can becomes almost totally ineffective.
For Instance, when the pH is 8.0 chlorine is only 22% effective and at 8.5 only 8% effective meaning you have to operate your pool with higher levels of Chlorine to maintain a safe pool - The recommended level of Chlorine is between 0.6 - 1.6ppm these are the maximum levels permitted in a public pool
pH balance : As the pH of the pool rises, Oxidizer / Chlorine action slows down. More Oxidizer / Chlorine must then be added to maintain proper sanitization.
The ideal pH range is between 7.2 and 7.6.
Total Alkalinity : If total alkalinity is low (below 80), the pH of the pool water may fluctuate widely . If the alkalinity is too high (above 140 ppm), it will tend to maintain pH at a higher level, thereby slowing the activity of the oxidizer.
To maintain the pH manually you would need to check it daily and on a well used pool twice or on commercial pools hourly - not practical.
Generally when we dose pool manually we tend to either "Overdose" = Wasteful and potentially harmful to the swimmers and the pool structure
or "Underdose" = potentially harmful to the swimmers and the pool structure
'Low Chem' water treatment systems are guaranteed to reduce or eliminate the use of Chlorine, Salt, and other toxic chemicals in your swimming pool.
Discover why 'Low Chem Systems' are becoming the healthy, environmentally preferred method of water treatment around the world.
We are sure you would like to reduce or eliminate the use of dangerous chemicals in your pool spa or home and save time and money.
Changes the calcium in your pool to a "Softer" form of calcium, acts as a flocculent maintaining the water clear and sparkling.
Maintaining Public Pools
Within the legal requirements and with maximum economy
More and more Public / Communal pool managers are struggling with the maintenance of their pool within the strict guidelines set by law.
The law relates to levels of:
Chlorine = 0.6 / 1.6 ppm*
pH = 7.2 - 7.6
Chlorine stabilizer = Maximum 75 ppm*
* ppm = Parts per Million
To maintain any pool to close tolerance you need to have a system of automatic control continually monitoring and adjusting the condition of the water to ensure it is acceptable.
The most economical and healthy systems are satisfied by using low level sea salt as the base chemical sanitiser, the salt is changed into Sodium Hyporchlorite via the electrolysis system, the production is automatically controlled by monitoring either the level of chlorine or the O.R.P. (Oxygen Reduction Potential) automatically of the water combined with pH monitoring and control - operating in conjunction in a commercially manufactured system large enough to cope with the varying demands placed upon a public pool from zero bathers to maximum in a couple of hours
In the case of public pools, it is essential to select the size of the salt-water electrolysis system by taking into account not just the volume of the pool, but also the maximum number of bathers per day and the climatic conditions (open air, air-conditioned, etc.).
