Abstract(s)
Water consumption in fish canning industry and the production of high polluted wastewaters are of great concern worldwide. In fact, in this type of industry a huge amount of water is used throughout all steps, including cleaning, cooking, cooling, sanitization and floor washing. It is also known a frequent change of raw material to be processed, with variation in flow rates and composition, which implies changes in wastewater characteristics. These variable operating conditions make the planning of a common treatment plant for all of the wastewaters produced in a single unit a challenging task. A treatment process suitable to treat this wastewater must be found in order to fulfil the limits imposed by the Portuguese legislation (Decree-Law No. 236/98) for industrial wastewater discharge. Therefore, it is important to analyze what are the main pollution sources of this type of wastewaters to be possible to identify its main characteristics in a quick and inexpensive way, in order to define an adequate sequence for its treatment.
