Abstract
A depuration system was designed and fabricated for cleaning of bivalves. The unit
consisted of a depuration chamber, biological filter and UV sterilizer. The system was
evaluated based on trial studies conducted using Villorita cyprinoides. Escherichia coli was
used as the indicator bacteria. Seeding of the animals by bacteria was carried out using
sea water of 10%o salinity and a bacterial concentration of 1x10' cfu ml'1. On 6 h exposure
of clams to the E. coli cell suspension, seeding was achieved to the desired level (6.69 x 10"
cfu g"1)- On depuration of seeded V. cyprinoides for a period of 15 h using the depuration
system complete elimination of E. coli could be achieved.
