Reverse Osmosis for Data Center Cooling Towers

Modern data centers and AI facilities generate enormous heat loads that must be continuously removed to maintain reliable server operation. Where evaporative cooling towers are used, the quality of the cooling tower makeup water can directly affect scale formation, corrosion, blowdown requirements, maintenance and overall water efficiency.

Reverse osmosis (RO) can play an important role in a data center water treatment strategy by reducing dissolved minerals in the makeup water before they enter the cooling system.

For facilities seeking to reduce freshwater demand further, RO can also be evaluated for treating cooling tower blowdown for water recovery and reuse.
