A lot of equipment is being used in the abattoir. All that equipment is not only necessary but also beneficial for the environment and also it effects the processing of slaughtering.
Pond systems are commonly used for secondary treatment of meat works waste matter. It includes anaerobic ponds, facultative ponds, mechanically forced aerated ponds, naturally aerated ponds and dissolved air flotation (DAF) cells, other package treatment plants.
For odour removal in abattoir operations following processing take place the cooking and rendering process, waste effluent treatment plants, slaughterhouses, product storage and handling areas, material drying areas, waste disposal techniques such as burning dead stock, animal holding pens, livestock transport vehicles, holding of carcasses before disposal, odors from skin handling, odours from skin sheds
Sources of odours in the rendering plant include stale materials and fugitive emissions from cookers. Odours in animal holding pens are produced by manure and urine. Slaughterhouse odours come from solid wastes such as paunch contents and blood residues.
Waste treatment ponds may produce gases such as methane, ammonia and hydrogen sulphide, which give rise to objectionable odours. Livestock transport vehicles entering the abattoir through residential areas may cause odour problems.
To cope all that problem that can be created by the abattoir following measures should be adopted like water pollution control measures, wastewater treatment plant, water conservation, treated wastewater re-use and disposal , storm water runoff, solid waste disposal measures, recycling, air emission control, bio-filtration, odour, noise control, operating hours, existing premises, proposed premises, ventilation plant, air conditioning, stunning boxes, compressed air equipment, pumps and rendering plant. Some of this equipment may need to operate 24 hours a day. An abattoir is serviced by a variety of vehicles including trucks and forklifts. |
