Beschreibung

This Code of Practice W 249 serves as basis for the removal of arsenic, nickel and uranium within the scope of drinking water treatment. Occasionally, arsenic, nickel and uranium reach concentrations in water used for drinking water abstraction that can necessitate the removal of these substances.

This Code of Practice describes the most important rules, which shall be observed when assessing the necessity of treatment measures to reduce the concentration of these substances and when selecting suitable treatment measures. It is assumed that measures have been examined and where necessary taken to prevent or minimise the introduction of these substances into the water in the first place and that these measures were not successful. The Code of Practice will make reference to such measures, but will not deal with them in detail.

It can analogously also be applied to small plants according to DIN 2001-1. The Code of Practice does not apply to water treatment in drinking water installations. As far as the disposal of accruing residues is concerned, reference is made to DVGW code of practice series W 221.
