Hitachi Aqua-Tech Engineering Pte. Ltd.

Many industries generate oily wastewater as a by-product during their daily operations. These wastewater have to be treated to suitable discharge standards to prevent environmental pollution and other harmful effects.

Hitachi Aqua-Tech is able to design systems to handle fluctuating wastewater conditions in terms of BOD5 and COD. We are also able to polish the treated water for re-use if the site does not have facilities for service / plant water.

The oily wastewater treatment generally consists of:

  • pH Adjustment
  • Coagulation
  • Flocculation
  • Sedimentation
  • Polishing if required
