  • Operating experience of desalination unit coupled to primary coolant system of CIRUS

    CIRUS is a 40 MWth, light water cooled research reactor located at Trombay, Mumbai. The reactor was shut down in 1997 for refurbishment and restarted in 2003. At Bhabha Atomic Research Centre R&D activities on desalination have led to development of desalination technologies based on Multistage Flash (MSF) evaporation, Reverse Osmosis (RO) and Low Temperature Evaporation (LTE). Based on LTE, a 30 ...

  • Energy and exergy analyses of the drying step of a copper-chlorine thermochemical cycle for hydrogen production

    Hydrogen can be produced by decomposing water, through thermochemical cycles, in an environmentally benign manner using nuclear energy. The copper-chlorine (Cu-Cl) cycle is one of the most promising low-temperature thermochemical cycles and involves five main steps: HCl (g) production; oxygen production; copper (Cu) production; drying; hydrogen production. In this study, energy and exergy ...

  • Treatment of wastewater from anaerobic digestion

    The Client The customer is power plant which produces biogas from biomass and sewage farm, through anaerobic digestion and thermal recovery, located nearby Munich in Germany. The Client’s needs Biogas is produced by the fermentation of organic substances of animal and vegetal origin in absence of oxygen (anaerobic process). This process produces a ...

  • Olive mill waste water treatment

    The production of olive oil generates two kind of waste waters: RINSING WATERS: the quantity is subject to change. It can be re-circulated, after the settling to remove the solids, or discharged directly. SLUDGE: vegetation water with additional water, whose quantity is subject to change. In case of traditional oil mills, the hot additional water flows to the inlet of the centrifuge. Part ...

  • Selection and economical evaluation of solar desalination technologies via DesalSolar software

    Worldwide projection indicated that in 2020 the situation of water resources in Iran reach to scarcity. Besides, global warming and energy crisis have forced countries to use renewable energy resources. Solar desalination technologies particularly in remote area of Iran could be a method to emancipate from this crisis. In this paper, all kind of desalination technologies were reviewed. Then, ...
