B Basic
information
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it comes to
the processing of drinking water (raw water). This operation manual
takes into consideration the current regulations 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 companies are permitted to make major modifications to
water supply facilities
and that tests, inspections and maintenance on installed devices are to
be performed at regular intervals.
In order to ensure drinking water quality, the issue of hygiene in
installations is becoming increasingly important. On the one hand, when
commissioning the installation there is the issue of cleaning by means of
flushing and then, depending on water hardness, the implementation of
measures to prevent lime scale. On the other hand, there are sanitation
measures such as sanitation flushing, disinfection, the removal of lime
scale and rust as well as the creation of a protective layer by means of
mineral dosing. These measures result from the latest requirements of
the German drinking water ordinance and standards, in particular DIN
EN 806-4.
The DVGW work sheet W 557 describes the "cleaning and
disinfection of drinking water installations"
It serves as the basis for avoiding and eliminating microbial
contamination and undesired deposits in drinking water installations as
defined by the drinking water ordinance. It describes the cleaning of
drinking water installations and the system disinfection of drinking
water installations or parts thereof and designates which disinfection
methods are to be applied and when as well as preventative measures
for avoiding microbial contamination.
The continuous disinfection of drinking water (drinking water
disinfection) is, in contrast, described in DVGW work sheet W 556
(under preparation).
