Scope

This part of BS 8525 specifies requirements and gives methods of test for packaged and/or site-assembled domestic greywater treatment equipment. This standard applies to treatment equipment where all prefabricated components are factory- or site-assembled by one manufacturer and tested as a single unit. This part of BS 8525 does not require specific water treatment processes to be used. However, it applies to equipment that treats bathroom greywater so that it is of a quality suitable for prescribed domestic uses in residential, commercial, industrial or public premises. It is not applicable to treatment equipment which processes waste from WCs and kitchens. The test methods described in Annex B and Annex D have been devised for the type testing of domestic greywater treatment equipment with a nominal treatment capacity of up to 10 m3 per day. They are intended to be carried out on greywater treatment equipment under controlled conditions using public mains water and synthetic greywater. These test methods are not intended for commissioning or validation of the on-site performance of the domestic greywater treatment equipment. NOTE 1 Recommendations for the installation, commissioning and validation of on-site performance of packaged and/or site-assembled domestic greywater treatment equipment as part of a greywater system are given in BS 8525-1. NOTE 2 Annex A specifies requirements for the greywater treatment equipment test set-up and preparation; Annex B to Annex D specify greywater treatment equipment test methods; Annex E and Annex F are informative annexes, the former giving recommendations regarding analytical methods and the latter providing an example of a product information sheet.
