What is reverse osmosis? Reverse osmosis is a water purification process that removes various types of contaminants, impurities, and dissolved solutes. Although reverse osmosis is not specifically designed to eliminate microorganisms, it can reduce the concentration of bacteria , viruses , and other pathogens due to the size of their molecules. Certain compounds dissolved in water, such as pesticides, chemical solvents, chlorine and pharmaceutical products , can also be remo

The evolution of reverse osmosis technology has involved the contributions of several scientists, engineers, and researchers over the years. Here are some of the pioneers who played a major role in the development and improvement of reverse osmosis technology. Sidney Loeb and Srinivasa Sourirajan: In 1959, Sidney Loeb and Srinivasa Sourirajan, American researchers, developed the first cellulose-based reverse osmosis membrane. Their work marked the beginning of serious resear

Water softeners are devices designed to reduce water hardness by removing or reducing minerals such as calcium and magnesium, which can be present in high concentrations in hard water. Here are some reasons why people use water softeners in their homes: Prevention of limescale deposits: Hard water contains minerals that, when they precipitate, form limescale deposits. These deposits can accumulate in pipes, household appliances (such as water heaters, dishwashers, and washin

Reverse osmosis and ultrafiltration are two separation processes used in membrane filtration to purify water and other liquids. Although they share some basic principles, they differ in their objectives, their filtration mechanisms, and their applications. Here are the main differences between reverse osmosis and ultrafiltration: Pore size of the membrane: Reverse osmosis: Reverse osmosis membranes have extremely small pores, allowing them to retain most solutes and even wate

Here is the literal translation, respecting your layout and all your rules: NASA (National Aeronautics and Space Administration) played an important role in the development of reverse osmosis, particularly in researching solutions to provide drinking water to astronauts during space missions. Reverse osmosis systems were considered key technologies for space missions, where efficient water management is crucial. NASA researchers worked on the development of water recycling sy

Reverse osmosis is a water purification process that uses a semi-permeable membrane to remove impurities and contaminants from the water. The concept of reverse osmosis dates back to the 1950s. Here is a literal translation, respecting your layout: Here is a brief history of reverse osmosis: Discovery of osmosis: The natural phenomenon of osmosis was observed long before the development of reverse osmosis technology. Osmosis is the natural movement of water molecules through

In France, tap water is generally considered safe and of high quality. The country has implemented standards to ensure the safety and potability of the water distributed to consumers. Tap water in France is regularly monitored and subjected to thorough analyses to ensure that it meets current health standards. Local authorities, generally the regional health agencies (ARS), are responsible for monitoring water quality in each region. They carry out regular tests on water sour

Il peut y avoir plusieurs raisons : 1. Beginning of the osmosis process: Rinsing of the membrane: During the first use, the reverse osmosis membrane needs to be rinsed to remove the preservatives and contaminants that may have accumulated during transport and storage. This rinsing can last several hours and may give the water a slightly different taste or smell. 2. Bacterial contamination: The biofilm: If the reverse osmosis system is not properly maintained, a biofilm can d

The question of whether it is safe to drink water from a water softener depends on the type of softener used and how it operates. Water softeners are generally designed to reduce the mineral content, particularly calcium and magnesium, in hard water. However, the softening process may involve the use of salt (usually regenerating salt based on sodium chloride) as part of the regeneration cycle. If your water softener uses salt, it is important to note that the sodium concentr

The choice of a filtration system for your domestic water depends on several factors: Quality of tap water: Check the water analysis of your municipality > https://sante.gouv.fr/sante-et-environnement/eaux/eau Identifiez les contaminants potentiels:  chlorine, limescale, pesticides, nitrates, etc. 2.Needs and preferences: Daily quantity of filtered water. Taste and smell of the water. Presence of sensitive individuals (infants, elderly people). Budget. 3. Available filtration

Symbols of refinement, orchids require special care to thrive over time. Among the essential factors for their good health, water quality plays a fundamental role. Osmosis water, obtained through a reverse osmosis system that filters out most mineral salts, heavy metals, impurities, and “forever pollutants,” proves to be an ideal solution for watering and caring for these demanding plants. In their natural environment, orchids benefit from pure, light rainwater. However, our

For the past few days, the media have been highlighting the launch of Dans Mon Eau , an innovative tool that maps chemical pollutants in drinking water in France. While tap water is generally of good quality, areas of non-compliance have been identified, particularly concerning nitrates, pesticides, and PFAS. In this context, many households are wondering: is it worth investing in a home water treatment system?   The associations Générations Futures and Data For Good have pu

Last week, our Aquavie Technologie team had the pleasure of attending the SETT Trade Show in Montpellier (from November 4 to 6, 2025) to present our latest water treatment equipment. It was a great opportunity to meet outdoor hospitality professionals, highlight our solutions, and establish new connections. Here is a full overview of this successful participation. Why was the SETT Trade Show a must-attend event? The SETT Trade Show, fully oriented toward outdoor hospitality
