Basic information (reverse osmosis system)
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it comes
to the processing of drinking water. This operation manual takes into
consideration the current guidelines and stipulates information that
you will need for the safe operation of your water treatment system.
Among other things, the regulations stipulate that
only approved specialist companies are permitted to make major
modifications to water supply systems
and that checks, inspections and maintenance on installed devices
are to be performed at regular intervals.
2 | Water
There is no chemically pure water in nature. Even in the
atmosphere, rain water absorbs various substances that change the
properties of the water to a greater or lesser degree. This process
continues as the water passes through the ground layers, with the
result that the water is enriched with increasingly large quantities of
materials. Carbon dioxide (CO
2
) is particularly important here, since
this substance increases the dissolving capability of the water even
more. Consequently, drinking water contains quantities of dissolved
sodium, potassium, calcium, magnesium, iron, manganese, copper,
zinc, chlorides, fluorides, sulphates and also nitrates, nitrites,
phosphates and silicates that vary greatly from location to location.
Due to dynamic substance and water cycles, harmful elements,
are increasingly being released into the natural environment.
These are only partially and slowly broken down by natural effects.
Consequently, these elements build up in the groundwater and
surface water over the course of time. Removing them from
natural water deposits again represents a particular challenge.
Grünbeck faces this challenge with the aim of producing unpolluted
drinking and industrial water.
The water works provide us with pure drinking water that is suitable
for consumption. However, if the water is to be used for technical
purposes, further treatment is frequently required.
