Flow limiters for reverse osmosis membranes

The flow limiter is an indispensable component in every reverse osmosis water filter. Only through the flow limiter, the process of reverse osmosis takes place in a membrane. The flow limiter, also known as a fixed pressure regulator, ensures that a certain amount of wastewater (retentate) can flow out of the reverse osmosis membrane within a certain time. Only then can the osmotic pressure build-up. For example, the inscription FLOW 700 means that at approx. 6 - 8 bar operating pressure of the reverse osmosis membrane (osmotic pressure, internal pressure), the flow limiter lets through a water quantity of approx. 700 millilitres per minute relatively constantly (depending on the back pressure).In addition, selecting the appropriate flow restrictor also determines the ultrapure water (permeate) to wastewater ratio. Since the VISION AQUA water filters are additionally equipped with the GREENOSMO® TECHNOLOGY, flow limiters can also be used, which do not comply with the usual specifications for ultra-pure water to wastewater ratio.Thus, the VISION AQUA water filters with reverse osmosis achieve a ratio of 1:0.8, which in plain language means that for 1 litre of ultra-pure water, the VISION AQUA water filter with reverse osmosis requires approx. 1.8 litres of raw water.

Der Durchflussbegrenzer ist ein unverzichtbares Bauteil in jedem Umkehrosmose Wasserfilter. Erst durch den Durchflussbegrenzer findet der Prozess der Umkehrosmose in einer Membran statt. Der Durchflussbegrenzer, auch als Fester-Druckregler bezeichnet, sorgt dafür, dass eine gewisse Menge an Abwasser (Retentat) aus der Umkehrosmose-Membran innerhalb einer bestimmten Zeit abfließen kann. Erst dadurch kann sich der osmotische Druck aufbauen. So bedeutet z.B. die Aufschrift FLOW 250, dass der Durchflussbegrenzer bei ca. 6 - 8 bar Betriebsdruck der Umkehrosmose Membran (osmotische Druck, Innendruck) eine Wassermenge von ca. 250 Milliliter pro Minute relativ konstant (Abhängig vom Staudruck) durchlässt.Zusätzlich wird durch die Wahl des passenden Durchflussbegrenzers auch das Reinstwasser (Permeat) zu Abwasserverhältnis bestimmt. Da bei den VISION AQUA Wasserfiltern zusätzlich die GREENOSMO® TECHNOLOGY eingesetzt wird, können auch Durchflussbegrenzer eingesetzt werden die den üblichen Vorgaben an Reinstwasser zu Abwasserverhältnis nicht mehr entsprechen.So erreichen die VISION AQUA Wasserfilter mit Umkehrosmose ein Verhältnis von 1:0,8, was im Klartext bedeutet, für 1 Liter Reinstwasser benötigt der VISION AQUA Wasserfilter mit Umkehrosmose ca. 1,8 Liter Rohwasser.
