Meat Processing Equipment
Where Does Meat Processing Wastewater Come From?
- Stockyards and Pens: live animals stay in holding pens for less than one day prior to slaughter. Wastewater results from watering troughs, washdown, and urine from the animals. Rain run-off from uncovered pens can also contribute to the wastewater flow.
- Slaughtering: as animals are stunned, suspended and bled, blood can spill or splash outside the containment area entering the waste stream during clean-up operations. Hogs are dehaired as they pass through a scalding tank. This and carcass washwater enter the wastewater stream.
- Blood Processing: as albumin and fibrin are recovered from blood for various uses, the blood water is either evaporated or sent to wastewater.
- Viscera Handling: beef and hog paunches are washed and saved for edible products. Wash water goes to waste.
- Hide Processing: washing and curing of hides contribute to wastewater with high levels of salts.
- Cutting: as carcasses are cut and trimmed, some material adheres to saw blades and conveyors. Equipment washdown sends these solids to wastewater.
- Meat Preparation: as cuts are cured, deboned, and packaged for distribution, spills from cooking equipment and curing solutions are sent to wastewater.
- Rendering: edible and inedible products are created as fats and water are separated from animal tissue. Spills from cooking equipment, collection tanks, and discharge from washdown contribute to wastewater.

Meat Processing Equipment for Particle Size and Volume Reduction
JWC meat processing equipment grinders are used to reduce the volume of waste and minimize transportation costs to rendering plants. JWC’s 7-SHRED-1 grinders can be used in pet food production as a pre-breaker for frozen blocks. Finally, JWC grinders, such as the HYDRO inline series, are used to protect pumps and other downstream equipment from troublesome solids.
- Effectively removes process water from solids
- High capture rates reduce BOD levels in further waste treatment processes
- Screens specialized for specific applications like oils, fats or meat
- Minimize maintenance costs with screens designed to stay cleaner
- Higher throughputs with a smaller screen maximizes the benefit of investment
- Smaller screens minimize loading on air scrubber systems
- Reduce waste volume to minimize transportation costs
- Protect downstream equipment from tough solids
