  • 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 ...

  • A connection between cycle chemistry & condenser configuration

    Abstract The most important contributor to power plant chemistry upset conditions and to the overall plant thermal efficiency is the condenser. In-leakage into the subatmospheric pressure, or shell side, of this important balance-of-plant component is responsible for most system wide corrosion, loss of availability and loss of heat transfer in boiler tubes due to deposition of ...

  • Power Generation

    Description Thermal power plants powered by either nuclear energy or fossil fuel located along a seacoast normally use seawater as a coolant in the steam condensers. These are typically once through cooling water systems Electro chlorination in above mentioned types of application has considered as the most effective, low operating cost and safety operation method in order to control the ...

  • Phosphonate removal from discharged circulating cooling water using iron–carbon micro-electrolysis

    Phosphonate is a commonly used corrosion and scale inhibitor for a circulating cooling water (CCW) system. Its discharge could cause eutrophication of receiving waters. The iron–carbon (Fe/C) micro-electrolysis technology was used to degrade and remove phosphonate from discharged CCW. The influences of initial pH, Fe/C ratio (FCR) and temperature on phosphonate removal were investigated ...

  • Utilization of artificial recharged effluent as makeup water for industrial cooling system: corrosion and scaling

    The secondary effluent from wastewater treatment plants was reused for industrial cooling water after pre-treatment with a laboratory-scale soil aquifer treatment (SAT) system. Up to a 95.3% removal efficiency for suspended solids (SS), 51.4% for chemical oxygen demand (COD), 32.1% for Cl− and 30.0% SO42− were observed for the recharged secondary effluent after the SAT ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • Chiller & cooling tower water treatment - case study

    Overview There are three main challenges for treating cooling water in both open and closed loops: scale, corrosion and biogrowth. Water System Challenges The traditional chemical treatment calls for chemicals to deal with these challenges. When scale is present, the condenser’s ability to transfer heat is reduced, causing higher pressure and higher ...

  • Use of cooling tower blow down in ethanol fermentation

    Reducing water consumption in bioethanol production conserves an increasingly scarce natural resource, lowers production costs, and minimizes effluent management issues.

  • 10 Most significance of cooling tower water treatment

    A cooling tower water treatment is the process which ejects the waste heats to the environment through the cooling of a water stream to redeemed temperature. The method which is used to eliminate the waste heat is the evaporation of water through the heat and cooling process. The cooling water tower is depended on air to cool for the working of the process. The cooling tower used for water ...

  • 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 ...
