  • Hot weather on its way ... Check the condition of your cooling tower

    The approach of summer is a good time to check the performance and, more importantly, the physical condition of your cooling towers. After all, it’s easier to repair a tower when weather conditions don’t put a strain on its cooling capacity. A cooling tower passes air over tiny droplets or the exposed surface of a water film. In both cases, a small amount of water is vaporized, ...

  • Monitoring once through cooling water - Case study

    The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often ...

  • Flow Rate Measurement in Full Pipes Using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • Guide To Coolant In Oil Test Methods

    Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, ...

  • 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 ...

  • Helplessly exposed to nature? How lightning storms can be measured

    Each day, there occur about 1,000 thunderstorms with 4-10 million lightning bolts worldwide. In average, 700 people per year are hit by such light discharges, of which 75% of the hits result in long-term damages. Between three and seven cases end fatal. The risk is particularly high in the open field and is fortunately decreasing. The reason for this is that we stay more often inside in cars and ...

  • (6) Test Radboud University Nijmegen Cool Puck toxicological

    Objective: The objective of this study was to test the toxic action or better the non existence of toxicity of a new anti-slime compound compound by using the responses of D. polymorpha. The "Cool Puck" was developed to detach easily the biofilm from all substrates in closed cooling water systems, especially for getting rid of slime and biofilm in ...

  • Monitoring Oil in Cooling Water - Case Study

    The Situation A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid ...

  • 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 ...

  • Arabian killifish (Aphanius dispar) embryos: A model organism for the risk assessment of the Arabian Gulf coastal waters

    Fish embryos are excellent models for studies aimed at the understanding of toxic mechanisms and the indication of possible acute and chronic effects. For the past 3 years, an Arabian killifish fish embryo test (FET) has been developed in our laboratory as a routine ecotoxicological test that can be used to support risk assessment of potential contaminants in Arabian Gulf coastal waters. Tests ...

  • Study on hydrodynamics and heat transfer of solitary wave on film flow with CFD method

    In this paper, a capacitance probe and high speed camera are adopted to study the solitary wave of falling film on large flat plate experimentally. Two types of solitary wave are studied with a Computational Fluid Dynamic (CFD) method based on the measuring data. The water–air shear stress on the interface of the solitary wave is modelled in the numerical calculation. The results indicate that ...

    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 ...
