Food Processing ETP for Poultry processing Industry by Richa Environmental Services Pvt Ltd.
Contact us for effluent treatment related solution for your Industry or troubleshooting of existing ETP
Quick overview of the poultry industry
Poultry processing involves receiving live birds, preparing them for consumers.
Poultry processing operation has almost 6 operations which involve water and generate wastewater of high BOD COD strength.
Processing involves defeathering, washing, eviscerating, washing again, chilling and cut up
Nature of Effluent from chicken processing Industry
Chicken flesh and blood will be found in the wastewater with all of the component material
Including blood cells, fats and oils, protein materials, and suspended solids including silt.
Wastewater generated is organic in nature and biodegradable.
Challenges associated with Effluent Treatment
Oil and grease content will be high.
High biochemical oxygen demand BOD would be due to the presence of blood.
Fat is soft and more soluble in hot water ( during summers in India )
Fat will not come at surface and will exist as emulsion (not settling nor coming up at surface)
Fat oil and grease will be slowly degraded by biological treatment process
Surface chemistry holds the fats, oils, and grease (FOG) in suspension.
Other major challenge is blood as blood contains red blood cells RBC, described as large particles that will not truly dissolve in water but will disperse uniformly throughout a volume of water in which it is placed
Blood must form a stable suspension in effluent The stabilizing force in the suspension of blood is electric surface charge.
Solution offered based on the challenges of the Industry
Effluent Treatment Plant with emulsion breaking system for fat oil and grease followed by Coagulation and flocculation and Biological Treatment
Fat oil and grease has specific gravity less than 1.0, and red blood cells have a specific gravity near to water 1.0
