©2020 Copyright. Sludge Separation, Hydrocarbio Recovery and Waste Volume Reduction to Improve Environmental Impact

CONTAMINATED SOLIDS from CRUDE SLUDGE: Dry, Burn or Digest?

Updated: Feb 29

When Hydrocarbons have been recovered and Water have been purified and discharged, final solids represent 10 to 20% of the original waste volume.


Hydrocarbon Contaminated Solids are made of sand, dirt, and other solids deposited by asphalt, paraffin and other heavy hydrocarbons. The solids undergo separation but some amount of contaminant remains attached composed of residual TPH, PAHs, metals and other contaminants.


Contaminated Solids Bottle Neck:

x No additional Oil to Recover

x Not compliant for Environmental discharge


Environmental discharge bottle neck is created when the operator is discouraged from further cleaning the solids for environmentally friendly discharge. Availability of clean and effective solutions is a major influencer of the petroleum waste management behaviors.


Therefore, several ultimate solutions are observed:

Containment: Drying of the waste and storage with possible possible natural degradation over time. Result is the accumulation of the residue from many sources until a treatment is found. Major point here is the waste volume reduction as 90% of original volume has been separated.

Waste Burning: The preferred and comfortable solution for the industry for the simultaneous hydrocarbon recovery and waste volume reduction. However, this process results in contaminated ash and Greenhouse gases, which produce negative effects. These facilities are mostly outside the Terminal Grounds. The this results in the continuous contaminment of the resulting residue.

​Digestion of Hydrocarbons: Bacteria digestion is currently used for petroleum waste management in small scale operations. The time required for bacteria to digest is highly dependent on the surrounding environment and the residue. Improving the performance and metabolism of the bacteria is directly related to their optimal working environment.

Digester Design Concept​

Proprietary Self-Contained Bacteria Digester is designed to:

  1. Activate Sludge Waste and Solids Residue for more efficient processing

  2. Provide a full spectrum hydrocarbon digestion

  3. Use wide selection of Bacteria Groups for specific and problematic waste components

  4. Aerobic and Anaerobic Processing Configurations

  5. Environment & Temperature Regulation for Optimal Bacteria Metabolism


Our systems do NOT use Pyrolysis nor Chemicals for separation, hydrocarbon removal and recovery.


Modular Digester Processing Results:

  • Guaranteed removal of TPH and PAHs, Achieves 0.05% TPH in solids

  • Oxidizes & Metabolizes Trace Hazardous Metals

  • Environmentally Friendly Discharge & Disposal of Solids

  • Meets Environmentally Friendly Discharge of Purified Water

  • Fertilizer Production

  • BioGas
