– Reverse-osmotic membrane unit (2 pc).
1. Body DWM-203 (1)
consists of tabletop, cover, stand, storage container and front panel. Four collectors (for
joining of replaceable filtering modules) are fixed in top plate, hydroautomatics block. Top plate is capped with cosmetic
cover, in the central part of which there is a handle that fixes the cap. In lower main body, stand, there is a pump for
increasing the water pressure in the DWM-203. In order that you can use clean water at any time in the required quantities,
the DWM-203 is equipped with a storage tank for clean water. On the front, the DWM-203 is covered with a decorative panel,
in which there is an electronics unit with control elements.
2. The composition of the preliminary water treatment unit (2, 3)
includes replaceable filter modules
K5 and K2.
The pre-treatment unit is designed to remove impurities from the water that can damage the reverse-osmotic membrane,
such as iron hydroxide and active chlorine.
3. The reverse osmosis membrane (4)
includes two replaceable membrane modules. Back-osmotic
membranes block purifies water from organic and inorganic compounds, salts, and softens water.
ATTENTION! The performance of the DWM-203 depends on the pressure
In the water pipe. The proper operation of DWM-203 at a pressure in the
water pipe below 0.14 MPa (1.4 at) is not guaranteed.
