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. ...

Cooling Tower Drift Elimination

ABSTRACTIn certain cases cooling tower drift (mist) can overwhelm conventional lower efficiency chevron mist eliminators. This paper explores an alternative strategy to control drift in those cases. The author uses a case history to illustrate conditions that can be expected to cause uncontrolled drift and to discuss a solution. The author acknowledges that the information presented is ...

Cooling tower case study

Cooling towers have always been difficult to control. Algae grow in the cooling tower itself and on the grids used. In addition to micro-organisms and biofilm, they reduce the efficiency of the cooling tower. Furthermore the risk of spreading Legionella is a serous factor to be reckoned with. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally ...

Determining Proper Cooling Tower Size

To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

The Control of pH and Oxidation Reduction Potential (ORP) in Cooling Tower Applications

The importance of keeping cooling tower water in proper chemical balance is becoming clearer. Cooling tower treatment control systems can limit scale formation to improve efficiency, limit corrosion to increase the service life of the cooling water system, and maintain a residual halogen level to reduce liability associated with biological growth, particularly Legionellae. The use of ...

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 ...

Upgrade Fill Media to Improve Cooling Tower Efficiency

One of the simplest and most cost-effective ways in which to extend the life of a cooling tower, improve heat transfer efficiency and reduce maintenance downtime, is to upgrade the cooling tower’s fill media to components constructed out of robust and non-clogging materials such as Polypropylene (PP), PVC or stainless steel. Fill is a critical component in the heat transfer ...

Republic Steel: CapDI for Cooling Towers - Case Study

Introduction & process description Water is often a hidden cost of industrial sites and can contribute significantly to operational costs. Cooling towers are used to reject heat through the natural process of evaporation providing cooled water across a broad range of applications. Due to evaporative losses, the water remaining in the cooling tower becomes concentrated with dissolved ...
