Data Center Cooling & Water

Data centers require reliable cooling systems to ensure consistent operation and maintain critical uptime. As data centers become larger with increased computing power density, their thermal management needs are also increasing.


Data centers have already made great strides toward sustainability by reducing energy consumption. Their cooling systems also use large amounts of water, so water sustainability is increasingly important, especially in areas facing water shortages. By implementing smart energy- and water-efficient cooling systems, operators can increase their Power and Water Usage Effectiveness (PUE & WUE) to achieve best practice standards.

Cooling Tower Expertise

Data centers commonly use cooling towers to reject heat. As coolant water evaporates, total dissolved solids (TDS) and scaling ions accumulate in the cooling system, resulting in the need to ‘blow down’ the remaining water and replace it with freshwater.


Saltworks’ innovations for improving cooling tower performance and reliability include:

  • Safely increasing cycles before blowdown by measuring scaling ions with advanced real-time ScaleSense sensors
  • Further boosting cycles by targeting and removing scaling ions with BrineRefine precision chemical treatment
  • Treating blowdown to recover freshwater for reuse while minimizing discharge volume with XtremeRO membrane systems and SaltMaker thermal systems

Industrial Wastewater Treatment

Heavy industry, manufacturing, and natural resource-based industries often use large volumes of water and generate wastewaters requiring treatment. Saltworks designs, builds, and operates industrial wastewater treatment plants with modern membrane, chemical, and thermal technologies that economically and reliably treat tough industrial wastewaters.

Cooling tower steam water blowdown

Achieving 70x Cooling Tower Blowdown Volume Reduction

Cooling towers are used by industrial plants to reject waste heat to atmosphere. A portion of the cooling water is blown down after a number of cycles of concentration, before the ions and metals reach their scaling limits. This blowdown requires management.
