Meat Abattoir Wastewater Treatment Ashford

The evolution of various industrial sectors and expansive urbanisation across the globe highly results in increased water consumption and also results in the generation of wastewater which is considerably diverse in nature, toxicity, and treatability.

Wastewater from meat abattoir ashford facilities is often high in strength hence it requires pre-treatment before its discharge into the environment or for reuse.

1. Effluent Treatment Plant – Proven and most effective solution for effluent/wastewater treatment in the meat abattoir industry:

Effluent Treatment Plant for the food and abattoir industry is developed and unified with an advanced technology without which water-borne pathogens can spread out and results in diseases and degradation of receiving water bodies.

Effluent Treatment Plant highly reduces the negative impacts of the effluents to aquatic ecosystems and to humans hence effluent treatment plant has proven to be an effective solution for effluent treatment applications.

The effluent treatment plant for food industries is the best way to overcome from water pollution. Its main objective is to produce a product that can be safely discharged into a watercourse or sewer.

Importance of Effluent Treatment Plant  for the meat abattoir Industry:
1. Efficient and practical
2. Convenient to use
3. More effective compliance with the law
4. Uplift industry image
5. Self-sustaining system

  1. Different treatment methods and levels of Effluent Treatment Plant:Here, are the 3 wastewater treatment methods used in Effluent Treatment Plant for meat abattoir industry to reduce the potential impact on the environment.
    1. Physical Treatment Methods
    2. Chemical Treatment Methods
    3. Biological Treatment Methods


  1. Effluent – How is it generated from the food industry and its characteristics:Most of the industries produce wastewater also known as effluent, as a by-product of their production process.Food industry requires a greater amount of water for processing food product. Wastewater discharged from food and drink industries vary with strength and characteristics. Effluent from food industry consists of high concentrations of suspended solids, total solids, BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), dissolved oxygen, oil and grease, fats, sugar, colour, preservatives, and usually nutrients such as nitrogen, ammonia, and phosphate etc.


The objective of treatment;

  • Eliminate the threat of diseases.
  • Convert the effluent into a readily reusable resource.
  • Conservation of water and nutrient.
  • produce a product that can safely be discharged into the water or sewer.


Characteristics of Effluent

  • Content readily biodegradable organic matter – ( Measured in terms of BOD )
  • Content grease, fat, and oil, tend to coat system
  • organic matter reduces oxygen transfer
  • Nitrogen present in 3 form,
  1. Organic N2
  2. Ammonia Salt
  3. Dissolved ammonia gas
  • Both aerobic and anaerobic bacteria
  • Comparatively high temperatures
  • Turbid
  • Off Colour
  • Dissolved gas ( methane, So2)

Generally, Effluent Treatment Plants undergo four treatment levels – preliminary treatment level, primary treatment level, secondary treatment level and tertiary treatment level. All these treatment processes/levels have the potential to treat the effluent from the food industry and bring down its parameters to the permissible ones.


  1. Pretreatment or preliminary treatment level:
    Being a first treatment level, it removes coarse solids and other large materials that are found in effluent to avoid damage to subsequent treatment units. Preliminary treatment operations typically include coarse screening, grit removal and, in some cases, breaking of large objects into the smaller objects.2. Primary treatment level:
    Its purpose is the removal of large solids from the wastewater via physical settling or filtration. It involves separation of floating material and heavy solids from liquid waste. The primary clarifiers can effectively remove 50-60% of the suspended solids. Oil and grease, organic nitrogen, organic phosphorus, and heavy metals associated with solids are also removed during primary sedimentation.3. Secondary treatment level:
    The major objective of this treatment level is to remove suspended solids and residual organic matter which can be done using aerobic and anaerobic processes. The activated sludge process is the most common option in secondary treatment. It involves aeration tank where oxygen is supplied to the microorganisms which result in removal of biodegradable dissolved and colloidal organic matter.4. Tertiary treatment level:
    The purpose of this treatment level is to further improve the effluent quality before it is discharged to the receiving environment. It removes the contaminants that were not removed in previous treatment levels. It involves disinfection process (using chlorine, UV light, ozone) which leaves no harmful residues that would need to be removed from the wastewater after treatment.
