Using The Ro 400 - Electrolux RO 400 Handbuch

USING THE RO 400

The RO 400 is a water purifier based on the reverse osmosis technique. This means that all
foreign substances are almost entirely removed - more than 99% in most cases. In a great many
industrial applications, there are strict requirements for a consistent and high level of water purity,
in order to guarantee function and to keep maintenance to a minimum.
Pure water also leads to a better finished product.
One area of application is in humidifying systems. Purified water minimises the risk of nozzles
furring up, and problems with calcium dust from the water being spread in the premises
disappear.
In addition, using water without any salt content gives a better humidifying result.
Below is a suggestion for how the complete installation might look. Note that tanks and valves
are not supplied with the water purifier.
The basic principle
The purified water leaves the RO 400 at (A) and then goes
into the solenoid valve (B). The valve feeds the first volume
of water from each operating cycle into the reject water
outlet via an airlock ( C ), and after a set time it then feeds
the water to an air humidifying system, for example. The
airlock prevents bacteria from the reject water outlet getting
back up the hose into the water purifier. The reject water
from the water purifier runs out through the connector (E).
Cold water is plumbed in at (F). In certain cases this
application needs a pressure tank to be connected up to the
purified water from the RO 400 (G). This means that
operational times are longer when the RO 400 starts up,
which is an advantage. In order to take water samples, or
water for any other purposes, e.g. battery water, a ball valve
