  • Mild cleaning: removal of 900 kg iron from a cooling water system - within 7 hrs - Case Study

    A professional cooling water treatment prevents the plant from corrosion damages. But in case corrosion should occur, severe damages can be the consequence. The cooling system needs to be cleaned. In contrast to a conventional cleaning with aggressive acids, Kurita suggests an innovative cleaning method: mild, material-protective and effective. With the mild Kurita cleaning method amazing 900 ...

  • Butane overhead condenser returned to original operating efficiency case study

    A Canadian energy company had fouling issues with cooling water at one of its plants that caused severe scaling in a butane overhead condenser. A 50% RYDLYME solution was recommended to dissolve the accumulated scale within the condenser. RYDLYME approach 330 gallons circulated for 6 hours at ambient temperature, reversing flow every half hour using a pumper truck. RYDLYME results Complete ...

  • What is cooling tower water treatment?

    It is a dynamic manufacturer and supplier of sustainable water and wastewater treatment solutions. The cooling tower water treatment is an integral part of a process in many in industries. The water treatment problems can very costly when the cause of heat transfers in the cooling tower, health and safety concerns and equipment failure. For this problem some company uses a unique approach, ...

  • Application of Ozone in Cooling Water Systems

    The first comprehensive study - bench-top laboratory investigations, pilot scale testing, and critical monitoring and evaluation of field applications - addressing the effects of ozone as a stand-alone cooling water treatment program is presented. The study also represents the first critical comparison of ozone-treated systems with non-treated systems. Excellent corrosion control can be attained ...

  • Evaluating alternative aluminium sources for chloride removal from recycled cooling water

    Chloride is important in promoting corrosion in cooling water systems, which leads to reducing the efficiency of heat transfer surfaces and shortening equipment life. Ultra–high lime with aluminium process (UHLA) is a potential new technology that has the ability to remove chloride and sulfate from recycled cooling water in addition to removing the majority of scale–forming compounds. The purpose ...

  • 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 ...

  • New Style Automatic Self-Cleaning Filters for Mill Cooling Water (Phase 1)

    ABSTRACT Replacement of hot-mill rolls is expensive and often requires production to cease during the process. Surface deterioration of rolls escalates as cooling water quality decreases. This manuscript will describe the installation and performance of a new cooling water filtration system in a northeast Ohio hot-roll mill that incorporates well proven suction scanning technology with ...

  • 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 Towers and Cooling Systems

    Water is used widely as a cooling medium in processes for many industries and public buildings. The use of an evaporative cooling tower is still the most effective method of heat transfer. Heat is transferred from hot process fluids into the cooling water through a heat exchange surface; consequently, the cooling water heats up. The evaporation of a small percentage of this cooling water in a ...
