Isabel Pereira Felizardo made the recommendation during a lecture on "Innovative techniques used in prospection and treatment of water".

Speaking at a workshop on " coffee with science and technology", the Chemical Engineer noted that the process is being tested, but still needs approval.

In addition to ozone, the sector also made testes with sudfloc, which is a polymer-based aluminum salt, added the chief of Lab department of Water Distribution Firm "EPAL".

Isabel Felizardo said that the intention is to reduce costs in water treatment, but unlike chlorine or ozone, for example, the process entails the creation of factories in water treatment stations.

"United Nations says that chlorine has some substances that may cause cancer, but does not recommend against its use. It suggests methods such as ozone. As the product takes less time in the water than the chlorine, the stations are recommended to have their own local productions or factories, "she  said.
