Page 6 - Opportunities in the Treatment of Water and Other Wast Streams

This section introduces treatment technologies currently used in the oil and gas industry. Information provided for each technology category includes a brief description of the technology, applicable contaminants removed, application with removal mechanisms, and a qualitative summary of benefits and limitations.
Pretreatment Technologies
Pretreatment technologies are categorized as technologies that remove constituents such as suspended solids, oil and grease, and organic matter. Pretreatment technologies generally precede desalination technologies to protect downstream processes from clogging and damage. Technologies referenced in this section pertain to case studies in this document and are not inclusive of every technology used by the industry. Additional technologies not listed include:
·Air stripping ·Centrifuge ·Oxidation
·Chemical precipitation ·Zeolites
·Granular activated carbon ·Biologically aerated filters ·Adsorptive or organic filters ·Disinfection ·Electrodialysis ·Electrodialysis reversal ·Electrodeionization Pond
Application:
Why: Initial separation of suspended solids before piping or trucking for off-site treatment or disposal as well as off-site facility use for separation after biological processes and conventional coagulation/ flocculation.
Benefits:
