There is disclosed, a desalination apparatus making use of a particles including covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent. For example, the complexing agent may include a crown ether. The particles are optionally used for removing salt from water, for example sea water. The apparatus optionally includes a magnet for magnetic filtering, concentrating and/or removing the particles and/or contaminant (e.g. salt). In some embodiments, the salt is then separated back from the particles using UV light. The remaining unclarified water may be washed out with the contaminant and/or used for salt production and/or disposed of (e.g. dumped back to the sea). Optionally, the particles are regenerated. For example, the regenerated particulars may be reused for further desalination steps (e.g. further salt removal from the clarified water) to clarify new input water.

An indirect heat transfer supercritical water oxidation system includes a supercritical water oxidation reactant system and an intermediate medium circuit. A control method thereof includes controlling two-process pressure and temperature increase, controlling pressure and temperature decrease and controlling normal operation. The present invention focuses on automatic control strategy of engineering practice of the indirect heat transfer supercritical water oxidation system. The system heating process adopts the idea of circulating heating, which effectively reduces the investment of the heating equipment avoids the mismatch between the working pressure of the two processes, and ensures effectiveness of the heat transfer between supercritical pressure fluid in the inner tube and the outer tube of the preheater/heat exchanger during subsequent heating process. The effective control of a reaction temperature and overpressure protection of critical equipment ensure a process effect and system safety.
