Abstract:
"Spa waters should be left untreated" says the dogmatic approach. Health authorities of European countries having traditional spa culture strictly control hygienic conditions of bathing in thermal/mineral waters. These regulations are based on the assumption that chemical treatment (disinfection) of such waters impacts their healing effects. However, a slow change of paradigm has been observed in studying the mode of action of spa waters that could help overcome recent attitudes. Organic content or the role of microbiome has also been emphasized by some authors recently. The article deals with possible interactions among aquatic microorganisms and the disinfection and health effects of spa waters and tries to explain the new findings in this field.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
States of Water
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
