Reverse Osmosis Under Sink System, Every Thing You Should Know

Installed reverse osmosis system under sink, their particularity is to deliver reverse osmosis water continuously, without storing it in a buffer tank

Installed reverse osmosis system under sink, their particularity is to deliver reverse osmosis water continuously, without storing it in a buffer tank. When choosing a reverse osmosis device, the direct reverse osmosis water system represents an interesting alternative to the traditional model.

Operation of the direct flow reverse osmosis

Before reaching the membrane, tap water passes through various cartridges. Their functions: provide a first level of filtration to protect the membrane in particular by trapping sediments, dechlorinating the water using activated carbon, or modifying the structure of the limestone by using KDF (mixture of copper and zinc). .. The membrane then removes 80 to 95% of the dissolved solids, the water thus filtered is of exceptional quality.

Depending on the reverse osmosis model, the membrane has a more or less significant daily filtration capacity: from 50 to 285 liters per day for the 75 GPD (Gallon Per Day) membrane and from 125 to 475 liters per day for the 125 GPD; these figures largely depend on the pressure, the temperature and the quality of the water to be filtered. The minimum recommended pressure for good performance of our direct flow reverse osmosis system is 2.8 bars.

Without a buffer tank, the flow rates will be respectively 9 to 11 liters per hour , direct reverse osmosis and 5 to 8 liters per hour.

The osmosis water/rejected water ratio is 1 liter for 4 litres. The discharged water can be recovered and used for non-food uses.

Connection of a direct reverse osmosis under sink system

Our two direct-flow reverse osmosis systems, located under the kitchen sink, are supplied with a specific small three-way tap that groups together most of the connections. A diagram is more explicit than a long speech, the representation below explains how to connect a direct reverse osmosis system

What maintenance for direct flow reverse osmosis?

Like most reverse osmosis units, the cartridge replacement interval on a direct flow reverse osmosis water system is 6 to 12 months. The state of the membrane, meanwhile, is checked using a TDS meter; the membrane has a lifespan of 2 to 5 years.

The maintenance of the direct osmosis unit is limited to these simple operations, since here, there is no tank to inflate to the correct pressure.

If you want to buy a space-saving under-sink reverse osmosis that is easy to install and maintain, the direct-flow osmosis simpure T1-400 is for you! The quality of water obtained by means of these devices is equivalent to that of a more imposing device, only the instantaneous flow rate is lower, but in use, this is not a constraint.
