The majority of freshwater used for livestock and crops worldwide is utilized in the meat processing industry. Large amounts of slaughterhouse effluent are produced by meat processing plants (MPPs), due to the slaughtering process and facility cleaning.

SWWs must undergo significant treatment due to their high organic and nutrient content, before they can be released into the environment in a sustainable and secure way. SWW treatment and disposal are thus essential, for maintaining public health.

Let’s understand how wastewater management is important in slaughterhouse industries.

Treatment of slaughterhouse wastewater

As a result of the high amounts of organics and pathogens present in SWW as well as cleaning detergents, meat processing plant (MPPs) effluents often contain a large amount of organic matter and the residues are slightly solubilized. SWWs are often analysed using bulk criteria due to the variable pollutant loads, brought on by the type and quantity of animals slaughtered in the meat industry.

Anaerobic treatment is the suggested biological treatment because it is effective at treating high-strength wastewater like SWW, while requiring less specialized equipment. Although, anaerobic treatment is efficient, total organic matter stabilization cannot be achieved by anaerobic treatment alone, hence post-treatment is necessary for anaerobically treated effluents to meet specified discharge limits.

Why is wastewater management important in slaughterhouse industries?

· Environmental

Raw SWW discharge has an effect on water quality, especially when it lowers dissolved oxygen (DO), which can cause aquatic life to perish. Eutrophication can also be brought on by macronutrients like nitrogen and phosphorus. These nutrient discharges result in uncontrolled algae growth and decomposition.

Aquatic life may be harmed as a result of the mineralization of algae because DO levels will drop. Finally, SWW may include substances like chromium and unionized ammonia that are directly hazardous to aquatic life.

· Public Health

The effects of the meat processing industry on the general public's health are related, to both direct interactions between slaughterhouse operations, and the surrounding communities as well as indirect interactions with the environment, which can be harmed by improper management of liquid effluents, solid waste, and offensive odours.

SWW contamination with viruses, protozoa, helminthic eggs, and bacteria can result in fatal gastrointestinal conditions, bloody diarrhoea, liver malfunctions, and other significant gastrointestinal issues.

SWW must be effectively treated before being discharged into water bodies, to prevent environmental contamination and harmful impacts on human health.

Conclusion

Infections can migrate from certain slaughterhouses to the final meat product that will be consumed. Additionally, it has been proven that sewage with animal origin contains hepatitis A and E viruses. In order to reduce environmental contamination and harmful effects on human health, SWW must be adequately treated before being released into water bodies.
