Seafood Wastewater industry

-

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 the 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 affluent, 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 wastewater and evaluating the efficiency of a seafood wastewater treatment system. 

 This chapter discusses the parameters involved in the characterization of seafood wastewater and presents pre-treatment and the first treatment for seafood wastewater, which are the only operations to scale back contaminant load and take away oil and grease from the 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 describe the foremost common operations of biological processes and discusses physicochemical treatments for seafood wastewater: coagulation, flocculation, disinfection, and direct disposal of seafood wastewater through land application, highlighting potential problems in land application.

  #SludgeDewatering   #ComboUnit   #Thickener +BeltFilterPress Krofta Engineering Ltd, India  Introduces newer version, enhanced capacity “Triple Wire Belt Filter Press” which is a COMBO UNIT (Thickener + Dewatering) Triple-Wire Belt Filter Press. This combo unit can work even at 0.8% sludge consistency without using separate thickener for dewatering Primary & biological secondary sludge generated at Industries & municipal plants. > In built flocculator comes as a standard supply with this new design > Low power consumption compared to other systems. The purpose of sludge dewatering is for waste minimization & to achieve overall cost efficiency for disposal. This machines has several combined processes added into one unit and it involves different applications such as chemical conditioning, gravity drainage and mechanical shearing and compression effect to remove water and dry up the sludge. Today, belt filter presses are widely used and it has become a standard for g

Tannery Wastewater Treatment

  Tannery wastewaters  are highly complex and its treatment is administered by physical or chemical or biological or a combination of those methods. From the review, it is often concluded that physical/chemical processes combined with the organic process is the better option for the treatment of tannery wastewater. The tanning industry is one of the oldest industries on the planet and therefore the problem of treatment and disposal of those wastes is perhaps as old because of the industry itself.  Tanneries wastewater  effluent is treated in many various ways. There are situations during which a private tannery applies all the below-described  wastewater treatment  steps on site. In other situations a private tannery may apply (on-site) only pre-treatment or a neighborhood pre-treatment or no treatment in the least, sending the effluent to a centralized effluent treatment plant. Nevertheless, treatment is important thanks to the wide selection of toxic effects on the environment caused
