Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.
reverse osmosis system
Diffusion and osmosis are thermodynamically favorable and will continue until equilibrium is reached. Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. The pores in special membranes let pass through water molecules but stop larger, organic and inorganic materials. This process under pressure is followed by carbon filter and basically all the organic particles are removed along with almost all the minerals.
Reverse osmosis filter for wine
Reverse osmosis system is not only used for filtration of water, but it is also used for filtration of wine. An ultra-fine reverse osmosis filter allows liquids – water, acid, or alcohol to pass through, but will retain color and flavor components. The reverse osmosis filter is used to remove the “permeate”, which is primarily alcohol and water and

is turned into high-proof alcohol that has no flavour. This lowers the alcohol in the wine. Though the equipment is expensive, the filter system made by Velo Group of Italy using the latest technology is more common among large wineries or producers that can charge super-premium prices.
