Slaughterhouses, Rendering facilities, and Abattoirs Effluents parameters to be treated Effluent from slaughterhouses, rendering facilities, and abattoirs is highly polluted and requires rigorous treatment before discharge or reuse. The wastewater typically contains a mix of organic matter, fats, oils, grease, and nutrients. Here are the key parameters that need to be treated:

 

Typical Effluent Parameters in Slaughterhouse/Rendering/Abattoir Wastewater

 

Special Contaminants (Rendering Plants Specifically)

 

High protein and lipid content

 

Volatile organic compounds (VOCs)

 

Temperature fluctuations (hot wastewater from cooking) slaughterhouses-rendering-facilities-and-abattoirs-effluents-parameters-to-be-treated

 

Treatment Requirements

 

To effectively treat this effluent, the treatment process typically includes:

 

Pre-treatment: Screening, grit removal, FOG traps

 

Primary treatment: Sedimentation, flotation (DAF)

 

Secondary treatment: Biological (aerobic, anaerobic)

 

Tertiary treatment: Nutrient removal, filtration, disinfection

 

Sludge handling: Dewatering, digestion, disposal
