discharged by gravity. The pumping action is rough on offal chunks resulting in an increase of smaller particles which may pass through the following screen. In addition, pumping is believed to increase the dissolved BOD by solubilizing suspended organic material. The shortcomings of offal fluming have been identified and addressed in many European fish processing facilities, and modifications have been and are being implemented at several fish processing facilities in the B.C. Lower Mainland. The main processing principles include: 1) Use of suction to remove entrails and to clean fish. This method represents a very effective means for reducing the contaminant loading, as well as the volume of wastewater discharged from fish processing facilities. However, to fully realize the potential of this processing method, the offal removed must be discharged directly into an offal hopper or bin. Discharging the offal into the wastewater collection system (including discharge directly to the screen) allows the mixing of the soluble fraction of the BOD with the effluent and will result in an increased contaminant loading. The suction method for dressing fish is at present only practised for freezer-dressed fish, as mechanised equipment available for cannery dressed fish has a higher throughput than can be achieved with the semiautomatic vacuum dressing lines. 2) Dry transport of offal and separation of offal from water prior to pumping. These waste handling methods are very similar and can result in a major reduction in contaminant loading and water consumption. Dry offal transport refers to the use of conveyors for the transport of offal rather than fluming offal. As water sprays are generally still required, both for equipment cleaning, and because of Department of Fisheries and Oceans' requirements, the conveyors generally are constructed with a belt made of wire mesh which allows water to drain, but retains large chunks of offal.
