Dairy Industry

Processing Plant – Effluent Treatment Plant 

Problem Statement

Our client is an Ayrshire milk processor in Pretoria who produces a range of products which contribute to a typical dairy effluent which was being discharged into an irrigation channel. This effluent did not meet the specification and the dairy was threatened with big fines and possible closure if a solution was not implemented.


After extensive lab trials, Watericon designed an effluent treatment plant to treat the waste stream to irrigation specifications. This stream could now be used for irrigation on the surrounding farms thus avoiding any penalties

Typical Plant Feed

  • Effluent Process Water from Diary – High COD: 1350 mg/l.
  • High SS

Performance Target

  • Capacity: 240m3/day
  • COD: <50MG/L
  • pH: 5.9 – 10


  • Flow equalization and pH correction
  • Chemical dosing
  • Coagulation & Flocculation
  • Dissolved Air Flotation



Watericon’s vast experience and technical know-how enables us to treat various difficult effluent across all manufacturing industries. Reducing waste streams and possible recovery options add to payback of these effluent plants.
