Pools are highly popular, with associated spa visits, swimming lessons for babies and aquarobics on the rise. To increase comfort for guests, pool temperatures have been raised in recent years, which promotes bacterial growth, thereby increasing demands on water purification systems to conform with permitted bacterial levels.
One way to keep bacteria levels down is to add more free chlorine, although, while the free chlorine does its job, the by-product, chemically bound chlorine, is formed. The bound chlorine causes problems such as red, itchy eyes, rashes and breathing difficulties. It is also the chemically bound chlorine that produces chlorine odour.
Today, Wallenius AOT is integrated into pool systems at commercial hotel facilities, on cruise ships and municipal bath houses around Europe.
Building Wallenius AOT into water purification systems improves water quality, reduces bacterial levels and lowers maintenance costs, while helping reduce the use of chlorine and levels of chemically bound chlorine to levels so low that even people with allergies can enjoy pool activities. In addition, lower chemical doses improve the environment for those working in and around pools. Decreased chemical emissions also entail a lower impact on the environment.
