BROMINE WATER TREATMENT FOR SWIMMING POOLS

Although bromine is not the most common treatment for swimming pools, it is as much efficient as chlorine and less restrictive.

Such as chlorine, bromine is a strong oxidant and disinfectant. It destroys bacteria, moulds, viruses and other organic materials that can be found in a swimming pool’s water.

Bromine inconveniences

Its price, as it is 30 to 40% more expensive than chlorine.

Non ecological: a high quantity of water must be emptied when bromine is overdosed.

A weekly check of the pool’s pH (between 7,5 and 8,0 for bromine) must be done as bromine efficacy depends on it.

SALT WATER TREATMENT FOR SWIMMING POOLS

As its name suggests, a swimming pool with salt is a pool filled with salt rather than chlorine or bromine water.

But it does not mean that the pool will not contain chlorine, as the salt molecule naturally contains chlorine.

The process consist in using the natural chlorine of the salt rather than pure chlorine which is more irritating for the skin, hair and clothes, worse for the environment and expensive.

A swimming pool with salt stands out from other standard treatments such as chlorine or bromine.

Salt allergy

OZONE WATER TREATMENT FOR SWIMMING POOLS

Ozone is one of the most natural and powerful water treatment for swimming pools and spas. We also use ozone to treat daily use water, such as tap water (Nice city makes the most of this treatment since 1907). Ozone is increasingly being used by professionals for public and municipal swimming pools.

Ozone is really efficient with bacteria, germs, organic material and viruses which are virtually destroyed by this treatment.

It is the best disinfectant for swimming pool and is stronger than any other manual or automatic chemical treatment. Ozone starts oxidizing algae as from 50 microgram diluted in 1l of water (µg/l).

A swimming pool treated with ozone stands out from chlorine, bromine and salt disinfectants in several ways. .

No skin or mucous membranes irritation.

Just the pleasure to swim in a spring water.

Ozone allergies

No allergies possible, as a water treated with ozone is entirely disinfected.

Dangers linked to an excessive exposure to ozone

None, as ozonation and desozonation are only made in the technical room, with no waste discharge in the pool as ozone re-combines in oxygen before going back to the pool.

Ozone inconveniences

The only inconvenient will be the price that need to be invested at first. But it will be quickly paid off with the gain on water consumption and energy savings.

Ozone water treatment is a wonderful solution for all owners of public and private swimming pools wishing to invest in an efficient, healthy and ecological process.
