| Research Abstract |
In the treatment of scallop-processing wastes, we have so far established a method for washing only the Cd-containing midgut gland by using a weak acid. Here, we used a weak acid to wash the soft parts obtained by eliminating the adductor muscle and shell in order to discuss the rationality of the total process, from washing of the soft parts to disposal of the waste fluid containing Cd. As a result, we established (a) a method for increasing the rate of recovery of washed parts by combining a simple heating unit and a dehydration unit ; (b) recovery conditions for preventing the loss of useful ingredients from the total washing fluid ; and (c) a system that included a process of safe disposal of final waste fluid.
