Certification - Water Treatment Chemicals

Water treatment chemicals and filter media used for the preparation of drinking water by water suppliers in the UK must be show to comply with the European Standards published as the BS:EN series. This is a requirement of the Drinking Water Inspectorate (Regulation 25 Letter 11/2000).

The standards specify the purity criteria for chemicals in terms of the contents of active ingredient and impurities and by-products. The same general layout has been used for standards for all chemicals. This covers:
   Identification;
   Physical and chemical properties;
   Purity criteria;
   Test methods;
   Labelling,
   Transportation and storage; and
   Informative

material relating to product manufacture, use in water treatment and emergency procedures. Similarly, a common layout has been adopted for inorganic supporting and filtering materials. Currently, over 80 standards have been produced and published as BS:ENs. A few remaining standards are in the final stages of preparation.

Treatment chemicals and filter media for use by water undertakers not covered by European Standards require Regulation 31 approval for use in the UK.

Copies of these standards can be obtained from BSi.

For further information on these standards please contact Mr Peter Jackson.
