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
