Ozone in Cooling Water Treatment
When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment ...

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 ...

Cooling Systems: Increased Costs from Mineral Scaling and Biological Fouling - Case Study
Mineral scaling and biological fouling are two of the most common problems associated with watercooled systems, and the costs from these issues can be enormous. By understanding how these issues affect cooling water systems, and their associated cost drivers, facility managers can make informed decisions on proper scale and biological fouling control. Scale Definition Cooling water typically ...

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 ...

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 ...

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 ...

Locating Leaks for Cooling Water Systems
This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline. Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises like ...

Application of an environmentally optimum cooling water system design in water and energy conservation
Recirculating cooling water systems are consist of a cooling tower and heat-exchanger network which conventionally have a parallel configuration. However, reuse of water between different cooling duties enables cooling water networks to be designed with series arrangements. This will results in performance improvement and increased cooling tower capacity. Research on recirculating cooling water ...

LA City Hall East Case Study
The City of Los Angeles completed their city hall in 1928 as the center of government for the city of Los Angeles, California. It is home to the mayor’s office and several meeting chambers and offices of the Los Angeles City Council. The East Hall, named James K Hanh City Hall East after former mayor James K Hahn, is home to the HVAC plant which supplies cooled water to both the East City ...

Bacterial community structure in cooling water and biofilm in an industrial recirculating cooling water system
Microbial fouling is a serious problem in open recirculating cooling water systems. The bacterial communities that cause it have not been fully understood. In this study, we analyzed the community structure of free-living bacteria and particle-attached bacteria in cooling water, and bacteria in biofilm collected from the wall of the water reservoir in an industrial recirculating cooling water ...

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 ...

Online Monitors for Oil Leaks in Cooling Water
Oil leaks in cooling water systems, usually from rotating heavy equipment such as pumps, compressors and turbines, contaminate the cooling water and are likely to damage the equipment. One method for detecting oil leaks in cooling water is to periodically grab a sample of the cooling water for analysis. Grab sample analysis has inherent problems. Sample analysis might require hours or days, and ...

TVA Cooling Water Conservation Project: Zeta Rod Case Study
Imagine a swimming pool, roughly the size of a football field, five stories deep. This is the volume of water (5.8 million gallons of water to be exact) that one U.S. Government Data Facility in the Southeastern United States has saved in one year by employing Zeta Rod® Water Management systems technology for its open loop water treatment and cooling water conservation program. Most ...

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 ...
