Cooling Tower Treatment

Filtration of recirculating water and treatment of tower blowdown to reduce waste is a common concern.

Evoqua offers a broad selection of filtration solutions for cooling systems which will remove suspended solids in the recirculating water stream. 
Removal of these solids can:        

  • Improve system efficiency 
  • Minimize annual cleanings 
  • Maximize chemical program effectiveness
  • Support effective microbiological control  
  • Reduce overall cost of operation


Evoqua also offers equipment and services using membrane technology to achieve greater than 95% recovery of cooling tower blowdown, with recovered water used for boiler feed applications.  Solid waste is pressed and disposed of while final, low volume concentrate is sent to evaporation ponds.
