Comparison between Conventional Treatment Processes and Advanced Oxidation Processes in Treating Slaughterhouse Wastewater: A Review

The blooming of the world’s human population and transition diet into a more westernized, high-protein has accelerated production slaughterhouse wastewater (SWW) as number meat processing plants (MPP) increased in past few decades. Conventional treatment processes (CTP) used treating SWW, such anaerobic processes, membrane electrocoagulation, have significant limitations, low efficiency, tendency to foul, high energy consumption, respectively. While advanced oxidation (AOPs) appear promising replacing former, they lack economic feasibility when single process. In this paper, limitations disadvantages CTPs SWW influents are evaluated. idea utilising AOPs “complementary” step rather than process is also discussed. review paper further explores variability different AOPs, Fenton, Electro-Fenton, Sono-Fenton, etc., their respective strengths weaknesses counteracting CTPs. incorporating resource recovery discussed towards end means generating additional revenue for industry players compensate operation maintenance costs treatment. integration new-generation AOP CTP while being able carry out future hurdle that must be overcome by scientists order produce versatile, powerful, sustainable, yet financially feasible operationally pragmatic system.
