Secondary Separation & Water Specific Purification for Discharge

Secondary separation is based on further cleaning the water from left over hydrocarbons and fine solids. When water is clean, it can return to be used as process water or the affluent can be further purified and discharged. Secondary separation and water purification can also be accomplished using digesters and bacteria to digest petroleum residue (TPH) and other contaminants.

Re-Use Water Purification

In order, to be able to reuse or discharge the treated wastewater, the dissolved oils, hydrocarbons and other constituents that sum up to the COD level must be removed (Al-Derham and Hidayat, 2014). Biological treatment has proven to be the most economical and reliable tool after preliminary oil/water separation.


Bacteria can digest and metabolize contaminants cleaning  the water, while a final filtration will separate organic affluent from bacteria and useable water for system reuse or discharge.

Traditional Water Treatment

  • Processed in filters and by clarifiers

  • pH Neutralized

  • Water is cleaned for reuse or environmentally compatible discharge

  • Optional: Integrated Reverse Osmosis System for Drinking Water Purification
