This solution aims to simplify the wastewater treatment process from slaughtering domestic cattle and animals by electrolytic oxidation and high-level oxidation reaction to remove COD, BOD, TSS, grease and over 95% color in wastewater.

1. Composition and nature of slaughter wastewater:

All stages of the slaughtering process use water with a norm of about 5 - 15 m3/ton of cattle and this amount of water is almost completely converted into wastewater. The main sources of discharge include:

  • Wastewater from slaughter process
  • Wastewater from cleaning equipment and cages
  • Wastewater for workers

Wastewater has the following characteristics:

  • Large amount of wastewater,
  • High concentration of solids (TSS), BOD, COD and
  • Large amounts of nutrients including carbon, nitrogen, phosphorus, etc.
  • A lot of grease
  • Stench
  • A lot of bacteria, mainly: Pathogenic bacteria, Coliform bacteria, microorganisms indicating the level of fecal contamination in water, sewage fungus.

2. The current popular slaughtering wastewater treatment process:

The traditional treatment process is cumbersome, the processing efficiency of each step is low, the investment cost is high and the required construction space is large.

Most of the current slaughterhouses use traditional technology but the output water quality is poor due to:

  • The design does not meet the heavy pollutant load and the complexity of the wastewater.
  • Not enough space
  • Limited investment budget

3. Is the NGO solution better?

We have the ability to simplify processes with high efficiency, here is a successful example:

Water quality achieved

Wastewater before treatment

Water quality after treatment

  • COD ~ 40,000 – 50,000 ppm
  • COD <300 ppm
  • BOD ~ 20,000 ppm
  • BOD < 900 ppm
  • TSS ~ 2000- 3000 ppm
  • TSS < 500 ppm
  • Grease~ 8000
  • Grease < 100 ppm
