  • Greenhouse based desalination for brackish water management using bittern evaporative cooling technique

    The Arab region is characterized by arid and semi-arid conditions with very limited renewable water resources. Most of the surface water comes from transboundary streams and most of the groundwater resources are fossil in nature. Water quality degradation and excessive use of pesticides and herbicides in agriculture pose severe environmental and health risks. The underlying research is a joint ...

  • CFD Analysis of Gas Cooling

    In many industrial processes, hot gas is cooled down due to the evaporation (boiling) of sprayed droplets. The effects of two different atomizer types, inner mixing air atomizing nozzles and flow back nozzles, on the cooling behavior inside a spray tower for a typical flue gas are discussed. The heat and mass transfer is computed using computational fluid dynamics (CFD). The interaction between ...

  • Exergetic performance evaluation of ejector cooling system

    Ejector-cooling model is developed to calculate the entrainment ratio and the area ratio representing throat to nozzle area. The developed model is validated with available experimental data in the literature. Parametric studies using the refrigerant R134a as the working fluid show that the Coefficient of Performance (COP) of the system is increased by increasing the generator and evaporator ...

  • Cooling Tower Blowdown Water

    Comparison of electrolytic oxidation v. ozone as biocide and reducing rate of TDS build-up in Cooling Tower Blow Down Water. Performed by Pureflow PtY Ltd of Singapore at Singapore Polytechnic Institute. Open evaporative cooling systems have been widely used throughout industry to remove heat from process systems and modern buildings for the purpose of air conditioning. As a result, due to this ...


  • Bypass filtration in open circulating cooling water systems

    An open circulating cooling system is a method to remove process heat and is applied frequently for industrial purposes. In these systems heat is removed by evaporation of water to the surpassing air in the cooling tower. However there are some environmental disadvantages such as addition of chemicals to prevent the cooling water system from microbial growth and corrosion. The application of ...

  • How to Save with Cooling Tower Credits

    Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper ...
