A small PALM oil refinery requiring a biological process for the treatment of their effluent generated at the premises.


Due to space restrictions as available land was scarce for the ETP, client required a compact solution which can be housed within available space.

THE SOLUTION - Palm oil mill effluent treatment

Based on pilot trials at site, a compact plant was offered to the client with following treatment scheme:

  • Equalization Tank
  • DAF
  • LEVAPOR IFAS Reactor
  • Secondary Clarifier

Compact ETP with DAF and LEVAPOR IFAS reactor


The plant is consistently delivering outlet COD of < 50 ppm under all operation conditions of the plant.


The project offered following benefits to the client.

  • Smaller foot print
  • Lower sludge production
  • Better COD values at the outlet with potential for reuse and recycle at economical cost.
