Why it matters

Until recently water treatment in pools has been all about clean blue water and well-distributed chlorine.

This is not the case anymore.

We now know that chlorine by-products are dangerous for swimmers, especially children. Chlorine by-products like chloroform and tri-chloramines are linked to asthma and cancer. Authorities in most countries now strictly regulate chlorine by-product levels.

Today water treatment in pools is all about creating a chlorine by-product free swimming environment, and at the same time clean blue water with well-distributed chlorine.

Scientific perspective

It all started with the Belgian professor Bernard who formulated the pool chlorine hypothesis in 2006: The hypothesis postulated that ”the rise in childhood asthma in the developed world could result at least partly from increasing exposure of children to toxic gases and aerosols contaminating the air of indoor pools”. Since then many scientific studies have been published both supporting and rejecting his pool chlorine hypothesis.

In 2011 the German health authorities (Umwelt Bundes Amt) found that evidence was sufficient to put out a press information on their homepage warning families with asthma and allergies about the by-product asthma risk. The press information especially suggested that these families not to take their children to baby swimming due to exposure of by-products to their underdeveloped lungs.

inBlue and the Founder & CEO Ole Gronborg, Ph.D. was featured in the recent publication of Whitepaper on Recreational Water published by ‘State of Green’ Denmark. The whitepaper describes how the inBlue design concept is insuring much fewer harmful chlorine by-products, and the shift to the new technology provides up to 30% savings in the use of chlorine.The World Health Organization (WHO) urges pool owners to focus on lowering chlorine by-products present in the water and air of recreational pool environments (read more on this here).

InBlue is the first concept in the world rethinking water treatment in pools, creating almost by-product free water and air.

Did you know
Chlorine does not smell. The typical smell of chlorine in pools is the dangerous bBy-product trichloramine that is formed when urine is chlorinated.
