The mixing system for ready-to-use flush solutions is characterized by an RO system, a mixing unit that is connected to the RO system and that contains a mixing chamber, to which high-purity water can be fed from the RO system and flush solution concentrate can be fed from a concentrate source, and a flush solution link connector, wherein the RO system and the mixing unit form a filling station, a mobile flush solution container that contains a pressurized container that receives a flush solution bag that can be coupled to the flush solution link connector of the mixing unit, and a computer and control mechanism for all measurement and monitoring tasks during the local production of a flush solution, wherein the mobile flush solution container and the filling station are provided with sensors by means of which wireless communication is made possible between the mobile flush solution container and the filling station.

Separation systems are described that may include forward osmosis (FO) membranes for offshore desalination and sulfate removal. The system may use submerged FO elements (e.g. operating underwater in the ocean). The system may use FO elements in combination with high-pressure reverse osmosis (RO) elements and processes. The system may use FO elements in combination with membrane distillation elements and processes. The system may create a suction and pressurized flow from a submerged FO membrane process to a reverse osmosis system on a platform, ship, or other offshore or “along shore” structure. The product water may be used for enhanced oil recovery (EOR).

A water mass transfer process providing a method and system to benefit conversion of poor quality water to attain high quality feed water or make-up water for a boiler. Wherein a low volatile solute is imbued within the water of a boiler, sufficiently so the elevated osmotic pressure of the boiler water can serve as a draw solution for forward osmosis based extraction of clean, high quality make-up water from poor quality water sources.

Disclosed herein is a acoustic concentration of particles in a fluid flow that includes a substantially acoustically transparent membrane and a vibration generator that define a fluid flow path therebetween. The fluid flow path is in fluid communication with a fluid source and a fluid outlet and the vibration generator is disposed adjacent the fluid flow path and is capable of producing an acoustic field in the fluid flow path. The acoustic field produces at least one pressure minima in the fluid flow path at a predetermined location within the fluid flow path and forces predetermined particles in the fluid flow path to the at least one pressure minima.

According to one embodiment, an amine-containing water concentration system includes an osmotic pressure generator and a carbon dioxide introducing unit. The osmotic pressure generator includes a treatment vessel, a first chamber to which the water to be treated is supplied, a second chamber capable of storing a working medium, and a semipermeable membrane that partitions the first chamber and the second chamber, which are located in the treatment vessel. The carbon dioxide introducing unit is capable of introducing carbon dioxide into the water to be treated.

A water treatment method includes: withdrawing water from the environment; filtering the withdrawn water in a membrane filtration unit; extracting a production flow from an underground formation containing hydrocarbons; separating and collecting production water from the production flow; filtering the production flow in the membrane filtration unit; collecting a treated water flow from the membrane filtration unit. An installation adapted for applying this method is also provided.
