A method for desalination of hot supersaturated water having a temperature of between 40° C. and 80°, includes contacting the hot water with a reverse osmosis membrane which is resistant to temperatures of between 40 and 80° C. without a prior cooling step.

The present disclosure provides a method for relieving a corrosive environment of a boiling water reactor, the method including a step of injecting hydrogen and a noble metal compound into water to be replenished into the reactor pressure vessel during a period of a generating operation of a boiling water nuclear power plant including the reactor pressure vessel. In the method, the hydrogen is injected into water to be supplied into the reactor pressure vessel, and the noble metal compound is injected into water in a line of the boiling water nuclear power plant in which a concentration of oxygen or hydrogen peroxide is stoichiometrically higher than the concentration of hydrogen at which hydrogen undergoes a chemical reaction to turn to water. Thus, when a noble metal is injected into a boiling water reactor, the noble metal can be restrained from adhering onto a pipe for an injection and other pipes, and thereby can increase the amount of the noble metal to be injected into a cooling water in a reactor pressure vessel.

A fluid treatment apparatus includes a ferrite assembly, a driver, and an oscillator circuit. The ferrite assembly is arranged in use to be capable of surrounding a conduit containing fluid to be acted on. The driver is arranged to generate a pulsed current to which the ferrite assembly is subjected whereby the driver is electromagnetically coupled to the ferrite assembly. The oscillator circuit is electromagnetically coupled to the ferrite assembly, and in response to the pulse generated by the driver, causes an oscillating signal to be generated which gives rise to an electromagnetic field which acts on the fluid in the conduit.

A system and method for delivering heat to a fluid in a fluid production pipeline. Particles are injected into a line adjacent the fluid production pipeline. The particles include a microencapsulated liquid exothermic phase change material configured to undergo a phase change by solidification and release heat at a selected temperature. The released heat is transferred to the fluid production pipeline.
