Abstract
Various illustrative embodiments of a process for enhanced flocculation and clarification of produced water from oil and gas wells using nanoparticles are provided herein. Certain nanoparticles can increase the settling rate of solids in produced water when used alone or combined with certain conventional flocculents.

A method of separating mature fine tailings from a suspension comprising mature fine tailings and water, the method comprising:
- introducing inorganic nanoparticles into the suspension such that the inorganic nanoparticles interact with the mature fine tailings, the inorganic nanoparticles having a diameter of 50 nanometers or smaller.
A method of separating solid materials from a suspension of produced water comprising solid materials and water from an oil and gas well, the method comprising:
- dispersing inorganic nanoparticles into the suspension such that the inorganic nanoparticles interact with the solid materials, the inorganic nanoparticles having a diameter of 50 nanometers or smaller.
