Seafood Wastewater industry

operations are often very high in Biochemical Oxygen Demand (BOD), Fat, Oil and Grease (FOG), and nitrogen content. BOD springs mainly from the butchering process and from general cleaning and nitrogen originates predominantly from blood within the wastewater stream. it's difficult to generalize the magnitude of the matter caused by these wastewater streams, because the impact depends on the strength of the effluent, the speed of discharge, and therefore the assimilatory capacity of the receiving water body. Nevertheless, key pollution parameters must be taken under consideration when determining the characteristics of a wastewater and evaluating the efficiency of a seafood wastewater treatment system.

This chapter discusses the parameters involved within the characterization of seafood wastewater, presents pre-treatment and first treatment for seafood wastewater, which are the only operations to scale back contaminant load and take away oil and grease from an effluent of seafood wastewater. Common pre-treatment for seafood processing wastewater includes screening, settling, equalization, and Dissolved Air Flotation (DAF). The chapter discusses biological treatments for seafood wastewater: aerobic and anaerobic treatments, describes the foremost common operations of biological processes, and discusses physicochemical treatments for seafood wastewater: coagulation, flocculation, and disinfection and direct disposal of seafood wastewater through land application, highlighting potential problems in land application.
