A process of dewatering oil sands/coal tailings includes generating nanobubble water, mixing a chemical dispersant into the nanobubble water to form a nanobubble-dispersant mixture, adding tailings to the nanobubble-dispersant mixture to form a nanobubble-dispersant-tailings mixture, and agitating the nanobubble-dispersant-tailings mixture to form an agitated nanobubble-dispersant-tailings mixture having a solid portion and a liquid portion. The solid portion is thereafter separated from the liquid portion. The agitation may be a centrifugal motion or shaking motion to agitate the nanobubble-dispersant-tailings mixture The chemical dispersant may be sodium hydroxide dispersant for asphaltenes and the volume of the tailings added may be substantially equal to the volume of the nanobubble water generated. An oil layer may further be skimmed off the liquid portion a polymer clarifier may also be added to the liquid portion. The process may be applied to achieve accelerated tailings processing for rapid and economic environmental remediation.

A method of desalinating water, including the steps of when electricity costs between a first predetermined price and a second predetermined price, fill water is pumped into a reverse osmosis desalination unit to yield desalinated permeate and saltwater having a first salinity, when electricity costs less than the first predetermined price, fill water is pumped into a reverse osmosis desalination unit to yield desalinated permeate and saltwater having a second salinity, and when electricity costs greater than the second predetermined price, pure water is flowed into a reverse osmosis unit to yield pressurized saltwater which is run through a turbine to generate electricity. The first salinity is lower than the second salinity.
