To understand Advanced Water Chemistry, you need to compare it with what is done in conventional pools.
Conventional Pool Water Chemistry
Conventional pool chemistry is complicated and
difficult to manage well. It has a
narrow operating range with tight limits on pH, chlorine, buffer, calcium and
stabilizer levels, and more. Simplistically, it has a small ‘sweet spot’ where
the water chemistry is good.
Challenges with conventional pool chemistry are several. Chlorine, as used in 99+% of pools, is a poor disinfectant at pH greater than 7.8 and gets progressively worse at higher pHs. Most pools drift continuously to their natural pH of around 8.5. pH must therefore be controlled by the constant addition of acid and buffer to ‘re-activate’ the chlorine and keep the pool correctly sanitised. Chlorine also breaks down quickly under sunlight, so stabilizers against the effects of the sun are used to maintain disinfection through the day.
High levels of organic matter from swimmers and the surrounds, get into the pool and form noxious and irritating chloramines, which are responsible for sore eyes and strong chlorine smells. Pool chemistry is affected by temperature, the pool surface, the amount of sunlight and shade, and bather activity.
All this makes conventional pools very difficult to manage well manually, unless the owner is prepared to spend a great deal of time on the pool. Effective pool control with conventional chemistry really requires automation based on chemical sensors, chemical dosing pumps and manual chemical addition based on test kit readings. It requires handling and storage of large quantities of dangerous chemicals.
While there are a few rules-of thumb that assist in manually managing pools, they are not universal or as effective as one might wish. Pool water is genuinely complicated and often presents a tedious maintenance task.
Advanced Water Chemistry
Pooled Energy’s Advanced Water Chemistry operates at the natural, equilibrium pH of the pool and in most cases requires little or no acid addition. It works so well because it has a large operating 'sweet spot' where the sanitiser is effective and the water is comfortable.
For sanitation, Advanced Water Chemistry uses
a combination of chlorine, generated by a conventional salt water chlorinator, and
stabilised bromine. Bromine is commonly
used in spas but, unlike chlorine, is effective at high pH. Bromine is also more stable at higher
temperatures (which is why it is so common in spas)……and it does not form
Instead of bicarbonate buffer, Advanced Water Chemistry uses a borax buffer system that works at high pH. It also uses magnesium salts to soften the water and protect the chlorinator and pool surfaces from calcium deposits.
Overall, Pooled Energy's Advanced Water Chemistry needs very low amounts of chemicals added to the water, compared with conventional chemistry. This results in less irritating, more pleasant, better sanitised water.
Pooled Energy Control systems also operate on
conventional chemistry pools however these are more expensive to operate, requiring
aspects such as active pH management via acid addition and do not match the
water quality of the Advanced Water Chemistry approach.
