Water treatment solutions Reverse Osmosis Osmopack Operating principle The membrane filtration process is a water refining technique. It is used for separating and concentrating molecules or ion species in solution, and/or separating particles or micro-organisms in suspension in a liquid. These processes use permselective membranes, which are thin barriers which, under the effect of an active force, retain or allow the passage of substances between the two separated media. The water must obligatorily be filtered before passing through the membrane. It first enters a polypropylene cartridge which will retain suspended matter greater than 5 microns in size. The water now ready to be refined successively passes through a granular activated carbon bed and an extruded activated carbon cartridge. These two stages help remove the micropollutants and organic matter contained in the water. The water, pressurised by a pump, then passes through a membrane frontally. The treated water (also known as the filtrate or permeate) passes through a final activated carbon cartridge which captures impurities and unpleasant tastes, before the water is stored in a container for consumption. The water that has not passed through the membrane and contains unfiltered elements (known as the concentrate) is discharged to the drain. The membrane has an absolute retention power more commonly known as the cut-off threshold. It corresponds to the membrane filtration threshold. Scope The osmopack is a module installed at the point of use of an installation. It is essentially fitted for household applications. Ensures maximum protection for water of mediocre quality. Installed at the point of use so as to only treat the water intended for use. Solution of potential interest for water not having undergone prior treatment.

Water treatment solutions Reverse Osmosis Technical characteristics It is strongly recommended to replace the filters regularly in order to maintain good water quality. The pre-membrane filter replacement frequency is dependent on the quality of the water to be treated. If the water is not subject to upstream treatment, it is recommended to replace the cartridges at least every 2 months. If applicable, the cartridges should be replaced every 4 months. The upstream filtering phases help prevent clogging of the membrane which results directly in treatment failure: head loss or poor membrane operation....
