ABSTRACTA Pacific shrimp (Pandalus jordani) processing plant was instrumented to measure water usage. A water balance was completed which identified fluming as a main user of water and subject to design improvements. Re‐use of water in fluming was investigated in pilot plant simulation to evaluate alternatives to fresh flow usage. A counter current flow system was designed to reduce water usage from 264 gpm to 156 gpm with acceptable microbiological quality.
