A process for the generation of power is disclosed. The process comprises receiving a wastewater stream containing organic matter and passing the wastewater stream to an anaerobic digester in which the organic matter contained therein is broken down to produce biogas. The liquid content of said wastewater stream is reduced before said stream enters the anaerobic digester by passing the wastewater stream through an osmotic power unit. The said stream is passed over one side of a semi-permeable membrane which permits the passage of water but not the passage of salts, an aqueous stream of higher salinity than said wastewater stream being passed over the other side of said membrane such that latent osmotic energy present in said aqueous stream of higher salinity is converted into electricity.

Used are a semipermeable Flat Sheet or Hollow Fiber Membrane in desalination and osmotic power generation of brackish, seawater and brines of 15% salinity or more. Charging each cell in the train of cells with a formulated brine having a specified ionizable inorganic salt concentration and type, without permitting mixing of the given brines among adjacent cells. Allowing the train to achieve water recovery exceeding 85% with concentrated rejected brine of 28-30% salt content.

An apparatus, system, and method to purify produced water from a wellbore using heat energy recovery. The apparatus comprises a wellbore with a wellhead attached to the wellbore; at least one energy recapture device connected to the wellhead of the wellbore with produced water, wherein the at least one energy recapture device captures heat energy of the production fluids including produced water, and at least one distillation device connected to a heat recovery device wherein the at least one distillation device uses at least a portion of the energy from the heat energy recovery device to heat a volume of the produced water in the distillation device to remove contaminants from the produced water to create purified water. The method comprises steps to use the apparatus and the system comprises a control panel that operates at least one energy recapture device.

The present system is for integrated management of associated gas and produced water at oil well extraction sites. The system includes a controller that makes gas allocation determination (e.g., directs conditioned gas to (i) gas flare, (ii) produced water reduction system, and/or (iii) generator) when a change in conditioned gas flow is detected based on first plurality of inputs. If the conditioned gas is directed to the generator, then the controller makes an electricity allocation determination (e.g., (i) increase a data processing operating rate on a data processing server, (ii) start up idle data processing equipment, (iii) direct generated electric current to a power grid, and/or (iv) charge a storage battery) based on second plurality of inputs. By operating the system of gas consumption and electricity production/consumption in an integrated fashion, benefits of flaring prevention, resource conversation, and more efficient economic operations are optimized to a degree not previously attainable.
