58 results about "Osmosis" patented technology

Osmosis (/ɒzˈmoʊ.sɪs/) is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations. Osmosis can be made to do work. Osmotic pressure is defined as the external pressure required to be applied so that there is no net movement of solvent across the membrane. Osmotic pressure is a colligative property, meaning that the osmotic pressure depends on the molar concentration of the solute but not on its identity.

Device and method for mixing liquids, also suitable for remineralizing and revitalizing osmosis water

Water purification, particularly through reverse osmosis systems, is gaining importance given the increasing levels of contaminants in tap water. Contaminants such as bacteria, agricultural runoff, hormones, plasticizers, and other pollutants pose a growing challenge. Water purification through reverse osmosis is a proven method for removing contaminants such as pollutants, microorganisms, and chemicals from drinking water. Despite its efficiency in removing contaminants, reverse osmosis also leads to the elimination of essential minerals that are important for human health. The present invention aims to develop a device for remineralizing and revitalizing osmosis water, which not only enriches the water with a balanced mixture of vital minerals, but also restores its original, natural energy structure.
