• Cooling towers are an integral component of many refrigeration systems, providing comfort or process cooling across a broad range of applications. They are the point in the system where heat is dissipated to the atmosphere through the evaporative process, and are common in industries such as oil refining, chemical processing, power plants, steel mills, and many different manufacturing processes where process cooling is required. They are
  also commonly used to provide comfort cooling for large commercial buildings including airports, office buildings, conference centers, hospitals, and hotels.
•  By design, cooling towers consume large
  volumes of water through the evaporation
  process to maintain comfort cooling or process cooling needs
• “Green” chemistry programs exist primarily to replace traditional treatments that have been deemed harmful for environmental reasons.
  “Green” chemistries often don’t result in
  improved thermal efficiency or reduced water consumption, but provide environmental
  compliance and reduced discharge of harmful or illegal substances.
• Traditionally, to eliminate scale build-up, most cooling towers throughout industry use chemicals
  that are increasingly hazardous to the environment and adversely affect wastewater treatment facilities.
• Chemical free water treatment for cooling towers are required to enhance the quality of water thereby reducing energy consumption of air conditioning chiller and improving COC (Cycle of concentration) for cooling tower without affecting its efficiency.
• There are a number of chemical free water treatment technologies available today
• Non-chemical devices (NCD) have been marketed in the water treatment industry to control or eliminate scale, corrosion, deposition and microbiological growths in cooling tower and boiler systems
• Technologies need to be evaluated for particular application after studying & comparison
• There are good number companies supplying these technology details & equipments
• Water consumption, Power consumption and Maintenance of these systems are to be assessed to make the Choice
• The initial expense of the “green” technology is considerably higher than the tried-and-true chemical treatment program
• Therefore Cost Benefit analysis can help decide the final choice
