“…People from developing countries in Africa, Asia, and South America have experienced serious gastrointestinal diseases, bloody diarrhea, liver malfunctions, and, in some cases, death associated with the presence of viruses, protozoa, helminthic eggs, and bacteria in SWW [5,27]. Furthermore, the presence of hepatitis A and E viruses has been reported in the sewage of animal origin in Spain.…”

“…AOPs are diverse and include gamma radiation, ozonation, ultrasound technology (UST), UV/H 2 O 2 , UV/O ₃ , and photocatalysis, among others, for the oxidation and degradation of organic matter. The disinfection is another benefit of AOPs, which can inactivate pathogens without adding additional chemicals in comparison to other disinfection methods, such as chlorination, preventing the formation of hazardous by-products [5]. Another main advantage of the AOPs is the high reaction rates as well as very low treatment time.…”

“…Thus, advanced oxidation processes (AOPs) could be used to improve the biodegradability of SWW and inactivate pathogenic microorganisms and viruses, left after biological treatment of the wastewater. Consequently, AOPs are an attractive alternative and a complementary treatment method to biological processes for the treatment of slaughterhouse effluents, especially as a posttreatment method [5][6][7]. Adopting combined biological treatment and AOPs for the treatment of slaughterhouse effluents is considered operationally and economically advantageous.…”

“…SWWs are classified as one of the most detrimental industrial wastewaters to the environment by the United States Environmental Protection Agency (US EPA) because the inadequate disposal of SWW is one of the reasons for river deoxygenation and groundwater pollution [4]. Thus, SWWs require significant treatment for a safe and sustainable release to the environment, and the treatment and disposal of wastewater from slaughterhouses are an economic and public health necessity [5,6].…”

The meat processing industry is one of the largest consumers of total freshwater used in the agricultural and livestock industry worldwide. Meat processing plants (MPPs) produce large amounts of slaughterhouse wastewater (SWW) because of the slaughtering process and cleaning of facilities. SWWs need significant treatment for a sustainable and safe discharge to the environment due to the high content of organics and nutrients. Therefore, the treatment and final disposal of SWW are a public health necessity. In this chapter, the regulatory frameworks relevant to the SWW management, environmental impacts, health effects, and treatment methods are discussed. Although physical, chemical, and biological treatment can be used for SWW degradation, each treatment process has different advantages and drawbacks depending on the SWW characteristics, best available technology, jurisdictions, and regulations. SWWs are typically assessed using bulk parameters because of the various pollutant loads derived from the type and the number of animals slaughtered that fluctuate amid the meat industry. Thus, an on-site treatment using combined processes would be the best option to treat and disinfect the slaughterhouse effluents to be safely discharged into receiving waters.

The effectiveness of photo-Fenton-like process to degrade aqueous polyacrylic acid (PAA) is investigated in a batch recirculation system using two photoreactors in series. The response surface methodology (RSM) using the Box-Behnken experimental design combined with quadratic programming is employed for the experimental design, the statistical analysis and the optimisation. The effects of the initial concentration of PAA, the initial concentration of H 2 O 2 :Fe 3þ , pH and the recirculation rate on the percent removal of total organic carbon (TOC)and the 'pseudo'-second order rate constant as the process responses are studied. The statistical analysis of the results indicates a satisfactory prediction of the system behaviour by the developed quadratic models. Optimum operating conditions to maximise the percent TOC removal are also determined.

The treatment of a synthetic pharmaceutical wastewater was studied using granular activated carbon (GAC) adsorption, UV/H2O2 process, and their combination. Experimental results reveal that GAC adsorption alone has 79% efficiency in total organic carbon (TOC) removal in 10 min breakthrough time with the dosage of 333.33 mg activated carbon/L. The adsorption data are fitted well with the Langmuir adsorption isotherm. The UV/H2O2 process alone at 6 h hydraulic retention time with optimum dosage of 4.25 mgH2O2/mgCOD shows 29 and 26% TOC reduction using 185 and 254 nm UV lamps, respectively. The kinetic modelling of the UV254/H2O2 process is developed using chemical oxygen demand (COD) and TOC as lumped parameters. A good agreement between model predictions and experimental data is confirmed. In combined processes, pre‐treated pharmaceutical wastewater by UV254/H2O2 followed by GAC adsorption process along with the desorption of contaminants from GAC and the subsequent treatment of the condensed steam by UV254/H2O2 process leads to 82 % TOC removal efficiency. On the other hand, the GAC adsorption along with UV254/H2O2 treatment of regenerant (condensed steam) from the desorption process leads to 88 % TOC removal at optimum conditions.
