Wastewater Treatment
Rocky Beem
2013 Smithfield Environmental Training Conference
Wastewater Sources Meatpacking Water Uses:
Cleaning (sanitation)
Process Uses (product-related)
Sanitary (restrooms) Cooling Towers and Boiler Blow-Down
System Leaks
Quantities Used Up to several million gallons per day
Daily fluctuations with cleaning
Types of Contaminants Organic Materials
Soluble and solids Meat processing Sanitary (restrooms) Ingredients (honey) Holding pen waste
Chemical Materials Treatment chemicals
(cooling towers / boilers) Sanitation chemicals Product ingredients
Inorganic solids (dirt)
Environmental Impact Oxygen Depletions
Organic material (BOD) Ammonia (and other nutrients) Grease
Toxicity Sanitation chemicals Ammonia Chlorine
Silting and Sedimentation Inorganic solids
Aesthetic Concerns Floating Grease Odors
Water Returns to the Environment !

On-Site Treatment Processes Further Processing Plants
Grease Traps Fine-Mesh Rotary Screens Dissolved Air Flotation (DAF)
Harvest Facilities Secondary biological treatment Anaerobic lagoons Activated sludge Remove soluble BOD
Discharge Permit Limits Limits on Discharge Quality
Organic Load (BOD) Suspended Solids (TSS) Oil and Grease (FOG / HEM) Ammonia / Total Nitrogen pH Total and Average Flow
General Prohibitions Can harm the POTW Create a hazard
Other Requirements Sampling and Analysis Reporting
Monthly / Quarterly DMR Exceeding Limits Conditions that could upset POTW Significant changes (e.g. flow)
Operation and Maintenance Per generally accepted standards
Permit Renewal (90 days) Mandatory Operator Training
Limited to Maryland Smithfield Requirements

Non-Compliance Consequences
Warning Letter Discretion of permitting agency
Notice of Violation (NOV) Exceed permit limit Late reporting Missed sampling event
Criminal Charges Neglect Falsifying data
Operator Training
Smithfield Training Program Web-Based (on-line) training 21 courses available Required within 6 months of employment Take courses applicable to job (processes) Tests included
Smithfield NOVs
By Media Air – 1 PCBs – 1 Wastewater – 27
Wastewater NOVs 1/3 of facilities pH, Chlorides, oil & grease, BOD, TSS
Significant Improvements
