Reverse osmosis system Watermelon RO-6

The water purification filter is based on the principle of reverse osmosis and consists of the following elements:


They are used for preliminary purification of water from insoluble particles, chlorine, organic substances before the water reaches the membrane, and help to increase the service life of the main cleaning element of the system – the membrane.


Simplified, it is a semi-permeable material through which only water and oxygen molecules can pass. Thanks to the membrane unit, the water flow is divided into permeate (clean water) and concentrate (dirty water, filtered, is discharged into the sewer).

Storage capacity

A tank for storing clean water. The useful volume is 10 liters.


The carbon cartridge filled with activated carbon absorbs gases dissolved in the accumulator water, thereby improving the taste of water.

Mineralizing cartridge

The main purpose of the mineralizing cartridge is to correct the pH to a value of 6.5-8, and to enrich the purified water with mineral salts, such as chlorides and bicarbonates of calcium, magnesium, sodium, and potassium. The amount of salts is comparable to the concentration of these salts in mineral waters sold in grocery supermarkets.
