Removal of Organic Constituents and Bacteria Count Disinfection from Fish Processing Wastewater by Using Ionic Cupric Copper

Abstract

The increasing consumption of fisheries product causes large amount of wastewater produced from fish processing industry. General wastewater treatment includes the use of harmful chemical such as chlorine. This research opens a new platform to treat wastewater by using ionic cupric copper which is also known as copper nanoparticles (CuNP). Copper nanoparticles are synthesized through chemical reduction method by using Copper sulphate pentahydrate (CuSO4.5H2O) as precursor and Sodium hydroxide (NaOH) as reducing agent. The physical characterizations of CuNP are carried out by using SEM and the chemical characterizations are carried out by using XRD and FTIR. The efficiency of CuNP to treat wastewater from fish processing industry are determined by the removal of COD, Total coliform and E.Coli. The optimum concentration to reduce COD is 1000mg/L which causes 59.4% percentage removal of COD. The optimum concentration for COD removal is used to determine the volume of CuNP needed to remove total coliform and E.Coli. The optimum volume for removal of total coliform and E.Coli are 40µL and 30 µL respectively.
