Filtration of cooling water is performed to remove particles that are suspended in said
waters in order to avoid;

• Erosion of piping, valves, seals, pumps impellers and heat exchangers.
• Reduced demands of biocides usage as microbiological activity is adsorbed onto
  these suspended solid particles.
• Avoid sediment build-up of these suspended solids within the cooling system which;
• Reduce heat transfer capability in heat exchangers
• Reduce heat rejection capability of cooling towers
• Promote localized under deposit corrosion (UDC)
• Promote anaerobic conditions for biological corrosion and harboring areas for
  legionella to take hold.
• Restrict cooling water flow through the system heat exchangers, cooling tower
  distributors, spray nozzles and fill.
• Increase the requirements to clean heat exchangers, cooling towers and basins.
