Bivalve Shellfish Purification Systems: Operating Manuals

Guidance on developing and operating six bivalve shellfish purification systems. They are frequently used by industry and are a proven technology.

Whilst a shellfish business or operator can develop their own systems for purifying bivalves, it is likely that such 'Do-it-Yourself' systems will require much more scrutiny and testing before they are shown to be working as they should.

Here we provide guidance on developing and operating five standard designs for bivalve shellfish purification systems, with additional guidance for developing and operating non-standard systems.

Originally developed in the 1990's, and reviewed in 2018, the six operating manuals offer technical and legal information to reflect current best practice.

The standard system models described in our 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 systems; this is carried out by a Local Authority.
