  • Seawater desalination utilising waste heat by low-temperature evaporation

    Utilisation of waste heat is one of the ecofriendly ways to produce low-cost desalted water. Keeping this in mind, Low-Temperature Evaporation (LTE) desalination technology utilising low-quality waste heat in the form of hot water (as low as 50?C) or low-pressure steam (0.13 bar) has been developed to produce high-purity water (conductivity ...

  • Nuclear desalination by waste heat utilisation in an advanced heavy water reactor

    The use of thorium for nuclear power generation is an important element of the Indian atomic energy programme. The design and development of the Advanced Heavy Water Reactor (AHWR) is a step in this direction. Intensive design activity is underway to set up a 300-MWe AHWR. The design of the AHWR incorporates several features to simplify the design and to eliminate certain systems and components, ...

  • Advances in nuclear desalination

    The Nuclear Desalination Demonstration Project (NDDP) at Kalpakkam aims to demonstrate the safe and economic production of good quality water by desalination of seawater comprising 4,500 m³/d Multi-Stage Flash (MSF) and 1,800 m³/d Reverse Osmosis (RO) plant. The design of the hybrid MSF–RO plant to be set up at an existing nuclear power station is presented. The MSF plant based on long tube ...

  • Breakthrough in energy efficient desalination technology

    Saltworks' proof-tested process employs an innovative thermo-ionic energy conversion system. The energy reduction is achieved by harnessing low temperature heat and atmospheric dryness to overcome the desalination energy barrier. The system works best in the dry regions that need water. Saltworks President Joshua Zoshi said, 'a desalination technology powered by atmospheric dryness is very much ...

  • The pebble bed modular reactor, desalination challenges and options

    The Pebble Bed Modular Reactor (PBMR) is a development lead by Eskom, the South African state power utility. The technology used is based on the previous German HTGR work linked to a direct cycle gas turbine (or Breyton Cycle) being developed in conjunction with Mitsubishi Heavy Industry. The initial commercial plant design has a thermal output of 400 MW with an electrical output (nett) of over ...

  • Thermodynamic efficiencies and GHG emissions of alternative desalination processes

    Three alternative approaches to desalinating seawater were evaluated with respect to their thermodynamic efficiencies and greenhouse-gas emissions. The technologies considered were multistage flash distillation (MSF), reverse osmosis (RO), and membrane distillation (MD). The analysis was based on published stream data from large-scale operational MSF and RO facilities and experimental-scale data ...

  • Experience feedback on operation of low-temperature vacuum evaporation-based desalination plant integrated with CIRUS

    CIRUS is a 40 MWth, heavy water-moderated, light water-cooled and natural uranium-fuelled research reactor located at Trombay, Mumbai. The reactor has been in operation since 1960 with an average availability factor of about 70% for about three decades. During the early 1990s, the reactor exhibited signs of ageing. It was refurbished and put back into operation at high power in 2003. Bhabha ...

  • Floating nuclear power plants

    Nuclear energy, in comparison with other modes of energy generation such as hydro, thermal and non-conventional sources, has high energy density with little environmental pollution or greenhouse gas emissions. The methodologies to check the problems of nuclear radiation hazards and waste associated with this technology are continuously being developed towards perfection. The nuclear plants are ...

  • A very high-temperature reactor self-sustainable oasis concept

    A VHTR-SSO for electricity, fresh water, and hydrogen production has been conceptually designed. The SSO uses a 600 MWth VHTR to drive the power cycle and generate net electricity, of 176 MWe. In the current configuration, about 100 MWe is sent to the power grid and the rest is used in a hybrid MSF-RO desalination plant to produce fresh water at a rate of 182 400 m³/d. Waste heat from the VHTR ...

  • Explore the capabilities of nanofiltration and ultrafiltration. Filters have similar looks, different applications

    Introduction Even if you’re an expert in reverse osmosis (RO) membrane technology, you may be overlooking some applications using often neglected cousins of RO: nanofiltration (NF) and ultrafiltration (UF). Although virtually identical in looks to RO membranes, NF and UF membranes serve distinctly different separation functions. Dramatic levels of resource recovery, efficiency ...

  • Climate Change and Wealth Creation

    Sir Richard Branson, Chair of the Virgin Group of companies, was once quoted as saying “Climate Change is the biggest wealth creating opportunity of our generation”. He is probably right. Every environmental problem, challenge or risk factor carries with it the potential for solutions, and those solutions often have the makings of a business opportunity. That is ...
