Mounting world population for the demand of meat products for protein needs has increased the establishment of meat products (fresh, cured, or cooked) manufacturing plants. However, these plants handle the activities of animal stabling, slaughtering/cutting, exsanguination, scalding, singeing, washing, skinning etc. These activities generate waste water which generally contains slurries, meat remnants, blood, hair, pieces of entrails, and surface fat. Altogether the water has a high oil and fat content, organic and suspended solids, nitrogen (ammonia and organic), phosphates, and detergents and disinfectants that are used during cleaning. Slaughtering process generate bulk of wastewater that normally comes from regular floor washing. The waste water carries lots of blood, bits of carcasses and animal wastes with large amount of suspended solids and liquid waste as well as lead to odour generation. Blood, is the one of the major dissolved pollutants of slaughterhouse wastewater, which discharges high concentrations of COD and other biodegradable components.
Discharging slaughterhouse wastewater without treatment creates a serious hazard to aquatic environment and pollution of irrigation water. This waste water contaminate both surface and groundwater, because during slaughtering processing, blood, fat, manure, urine, and meat tissues are lost to the wastewater streams.
As seen, for each step of slaughtering process, wastewater will be generated in huge volume with oily and fat content. Almost 5 and 10 liters of water required for per kilogram body weight of live animal. So for whole slaughtering process, it will vary beyond tons. Discharging huge volume of slaughterhouse waste water to the sewer and then diverting to municipal treatment plant is often become an issue for governmental bodies with their tighten rules. So based on this fact an option of installing an onsite slaughterhouse water treatment plant will facilitates to manage all the waste and even save the environment from solid waste, liquid waste and Odour generation.
Onsite installing of slaughterhouse waste treatment plant focuses primary to reduce BOD/COD, which are highly biodegradable. The plants process provides a sustainable long term solution that reduces organic waste to landfill and minimizes airborne odours. The installation also manages to reduce the blood stream and Ammonia levels, within the discharge to main sewer both economically.
Emvees Technical service offers the service with cost effective solution. Emvees also encompasses an additional solution for the reuse of the discharge water after significant cleaning as an option. Emvess waste water treatment goes with three main procedures like solids process, liquid process and odour control in slaughterhouse.
The three Processes of slaughterhouse waste treatments mentioned above are well-organized and robust. However, it results to lower the operational cost and effort.
