Optimizing Your Water Filtration System

tower filter

While water treatment focuses on particulate smaller than 40 microns, larger debris can be removed through a filtration system. The combination can optimize your cooling tower’s system by:

  • Lowering cost of chemical treatment
  • Optimizing your water treatment program
  • Maintaining heat transfer efficiency and increasing system life


A cooling tower inspection will provide an initial assessment on the type of filtration system needed to optimize a cooling tower’s performance. Filtration methods include the passing of water through mesh strainers, or the use of centrifugation to remove debris.

What to Consider When Choosing a Water Filtration System

Before selecting a filtration system, consider the following:

  • What's the downtime cost and productivity loss due to cooling tower fouling, clogging, or excess buildup?
  • What type of buildup is most problematic?
  • Which part of the cooling system needs the most attention?
  • Which filtration system provides the most surface area for debris removal?
  • Can the filtration system be installed without shutting down the cooling tower or interfering with routine operations?
  • What is the cost associated with both the filter and installation?
  • How easy is the system to install and maintain?
  • What type of preventative maintenance is required to maintain the filtration system
  • What is the payback on the cost of the filtration system?


Answering these questions will provide a better understanding of filtration options available and the best one for your system. The benefits of making the right selection far outweigh the costs of installation and upkeep.
