Pathogen Concerns

Meat processing wastewater may contain E. coli, Salmonella, Listeria, and other pathogens of concern. Effective treatment is essential for protecting public health and meeting stringent discharge requirements.

E. coli O157:H7

Pathogenic E. coli strains from cattle and other livestock require comprehensive treatment for safe discharge.

Salmonella

Common in meat processing, Salmonella requires multi-barrier treatment including biological reduction.

Listeria

This hardy pathogen requires effective advanced biological treatment and final disinfection for complete removal.

Regulatory Compliance

Discharge permits require fecal coliform counts below 200-1000 CFU/100mL depending on jurisdiction.

Multi-Barrier Treatment

Reynolds & Bauhm systems combine advanced biological treatment, filtration, and disinfection to achieve comprehensive pathogen reduction. Extended aeration MBBR systems with membrane filtration provide reliable pathogen removal.

Physical Separation

Screening and DAF systems remove solids and organic matter that harbour pathogenic organisms.

  • Removes 90%+ of suspended solids
  • Reduces organic pathogen carriers
  • Protects downstream equipment

Biological Treatment

Extended aeration MBBR systems provide natural pathogen reduction through microbial competition.

  • 90-99% pathogen reduction
  • Extended contact time
  • Stable microbial ecosystem

UV Disinfection

Ultraviolet disinfection provides chemical-free pathogen inactivation for final treatment.

  • No chemical residuals
  • Proven 4-log reduction
  • Automated lamp monitoring

Pathogen Control Process

Preliminary Screening

Coarse and fine screens remove solids that can harbour and protect pathogenic organisms.

DAF Clarification

Flotation removes suspended organic matter and associated pathogens from wastewater.

Biological Treatment

Extended aeration MBBR provides natural pathogen reduction through microbial competition.

Secondary Clarification

Lamella clarifier separates biological solids, removing pathogens attached to sludge.

Filtration

Sand or multimedia filtration removes remaining suspended solids and attached pathogens.

UV Disinfection

Final UV treatment inactivates remaining pathogens to meet discharge requirements.

Disinfection Options

UV disinfection or chlorination provides the final barrier for pathogen control. Automated dosing and monitoring ensure consistent performance and compliance with fecal coliform limits.
