Indonesia: Hazardous Waste Water Pond Cleaning


The Challenge

The client had a waste water treatment effluent pond that required a clean-up after 20 years of being in operation. The high level of water content in the effluent sludge would have meant an exteremely costly  exercise for a thermal treatment process for the sludge.

Our Approach

We separate the task into clearly defined stages:

  • Sludge pond cleaning
  • Pre-treatment /filtering
  • Dewatering of sludge
  • Packaging
  • Transportation


Geocycle deployed a filter press to dewater the waste, reducing the moisture content to a level acceptable for co-processing.

Further improvement and optimization the dewatering process reduced the water content by more than 40 percent.
