benefits summary

With all the unique properties of clinoptilolite working in Zelbrite, the pool water not only gets a superior "physical" treatment but an additional "chemical" treatment, resulting in cleaner pool water. No other filtration medium on the market (such as sand and diatomaceous earth (DE) can produce this "double whammy" treatment of pool water!

The difference in "physical" performance can be explained by the fact that the surface of sand is quite smooth and non-porous. Contaminants can only be trapped between the sand grains. Zelbrite not only traps contaminants between grains, but additionally traps contaminants onto its vast pitted surface area and within its porous structure. Thus its ability to attract, capture and hold dirt and other contaminants is far greater than conventional pool filter materials. It also traps finer particles such as colloids and can filter to diatomaceous earth standards or better. This translates to exceptional pool-water clarity and sparkle.

From the "chemical" perspective, it is important to understand that most contaminants in pool water are of organic origin produced by bathers (human detritus from skin cells to urea). These complex organic substances containing nitrogen eventually breakdown to ammonia/ammonium. Chlorine, used for disinfection, combines both with the ammonia and with these organic pollutants, to form both irritating and dangerous compounds.

For example, when ammonium ions mix with chlorine, chloramines are formed (these register as combined chlorine in testing). Chloramines are the compounds generally responsible for the acrid odours and burning eyes in pools.

By removing ammonium by ion-exchange, Zelbrite pool filter media significantly reduces the propensity to form these compounds. Additionally, the chemical adsorption qualities of Zelbrite, remove harmful organic pollutants and again lessen their interaction with chlorine.

Besides the superior pool water quality produced for swimmers, chlorine usage is markedly reduced as ammonium and organic contaminants are removed, and the chlorine is utilised in disinfection (free chlorine) rather than combining (combined chlorine) with contaminants.

As a consequence the ancillary chemical requirements are reduced and total dissolved solid (TDS) build-up is also reduced.

 

Zelbrite - the superior swimming pool filter media, delivers exceptional pool-water clarity and sparkle.
