4. THE DEVICE AND PRINCIPLE OF OPERATION RO-70S
The main components of RO-70S:
1 - Housing RO-70S assembly;
2 - Preliminary water treatment unit (cartridge K3);
3 - Reverse osmosis membrane unit (cartridge RO-50S);
4 - Water conditioning unit
(cartridge for potting or conditioning of water).
ATTENTION! The efficiency of the RO-70S depends on the pressure of the water supply. Reliable
operation of the RO-70S at a pressure in the water pipes of less than 0.2 MPa (29 psi) is not guaranteed.
1. Under reduced pressure in the water supply system, to obtain the optimum drainage ratio and clean
water it is recommended to use a pressure boost kit.
The RO-70S housing (1) consists of an upper plate in which two collectors are fixed for connection of the
replacement cartridges and hydro automatics of RO-70S. The top plate is covered with a decorative lid fixed
by three plastic fasteners.
On this decorative lid a post-filter-filter is fixed. An important part of the RO-70S enclosure is the storage
tank for clean water. Since the performance of the membrane cartridge is small (depends on the type of
membrane element, water temperature and pressure in the water pipe), the water after the membrane
cartridge is fed to the storage tank so that you can use clean water at any time and in the desired quantities.
2. The prefilter unit (2) includes a plug-in filter cartridge K3. The pre-water treatment unit is designed to
remove impurities from water that can contaminate the membrane, such as iron hydroxide and active
chlorine.
3. The block of membrane (3) enters the reverse osmosis membrane RO-50S. The block of reverse osmosis
membrane cleans water from organic and inorganic compounds, salts, and also softens water.
4. The water conditioning unit (4) includes a post-filtration cartridge or a water conditioning cartridge
Aquaphor (hereinafter – post-filter) depending on the RO-70S version. The water conditioning unit removes
extraneous smell and taste, and, depending on the performance, mineralizes the water.
How the RO-70S works
From the cold water supply network, water enters the RO-70S inlet and passes through a pre-filter. Further,
through the automatic valve, water enters the reverse osmosis membrane unit. The membrane cartridge
has two outputs: a clean water outlet and a drainage water outlet. Passing through the flow restrictor,
drainage water goes to the sewer.
Purified water enters the storage tank, which has a built-in diaphragm separating the tank from into two
cavities: accumulative and technical. In the storage cavity there is completely purified drinking water, and
in the technical – tap water. During the collection of clean water in the storage tank of the system, tap water
from the technical cavity is forced into the drainage, without creating resistance to a set of clean water. As
soon as the storage tank is full, the automatic valve will block the flow of water into the RO-70S. Once the
storage tank is full, the automatic valve will block the flow of water into the RO-70S.
When you open the tap for pure water, the tap water enters to the technical cavity through the inlet valve
and squeezes the purified water out of the storage cavity through the water conditioning unit to the tap for
clean water.
This action activates the automatic valve and opens the water supply to the RO-70S storage tank.
