  • A rapid and simple capillary electrophoresis method for indirect determination of the biocide 2,2-dibromo-3-nitrilo-propionamide (DBNPA) in cooling waters

    A capillary zone electrophoresis (CE) method was developed for the determination of the biocide 2,2-dibromo-3-nitrilo-propionamide (DBNPA) in water used in cooling systems. The biocide is indirectly determined by CE measurement of the concentration of bromide ions produced by the reaction between the DBNPA and bisulfite. The relationship between the bromide peak areas and the DBNPA ...

  • 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 ...

  • Cooling Water Treatment in a Thermal Power Station

    Ozonia Switzerland and a water treatment company have successfullyinstalled and commissioned a turnkey, fully assembled, containerised ozone system in a large Thermal Power Station. The ozone produced by the plant will be used to treat the raw make-up water being fed to the cooling towers and to compliment the proprietary biocide dosing program being used in the cooling system at the ...

  • Hospital cooling tower application

    The Challenge: One of the largest teaching hospitals in Illinois wanted to improve safety and “green” operations in their cooling tower water treatment chemical regimen without sacrificing effectiveness. The Solution: Replacement of bulk bleach with on-site generated MIOX® mixed oxidant solution, Earthwise reduced the hospital's liability from ...

  • Ozone treatment for cooling towers

    Abstract The use of ozone as a maintenance treatment for cooling towers has good potential for operation and maintenance savings in the Federal secior. A small amount of ozone acts as a powerful biocide thai decreases or nearly eliminates the need to remove quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system. ...
