Bivalve Shellfish Purification Systems: Operating Manuals


Whilst operators can develop their own systems for purifying bivalves, it is likely that such 'DIY' systems will require much more testing before they are able to be successfully challenge tested by the licensing authorities.

At Seafish, we provide guidance on developing and operating five standard designs for purification systems, with additional guidance for developing and operating non-standard systems.

Originally developed in the 1990's, our highly regarded manuals have recently been reviewed and the technical and legal information updated in March 2018 to reflect current best practice and legislation developments.

The standard system models described in our Seafish manuals have been extensively tested, are frequently used by industry, and are a proven technology. There are a number of UK suppliers of the equipment needed to install these systems. 

Please Note: Seafish does not approve system installations; this is carried out by a Local Authority.

All six system operating manual PDFs can be accessed via the 'Search documents and articles' function found top right of this page.
