Data Centres Water Treatment
Data Centres – Tailored Water and Wastewater Treatment
Modern data centres depend on reliable water treatment systems to enable efficient cooling. Water quality directly affects system performance, energy use, and uptime. Hydroflux provides advanced water and wastewater treatment systems that protect assets, minimise downtime, and support sustainability goals for hyperscale, edge, and colocation facilities.
Why Effective Water Treatment Matters
Cooling systems rely on water to transfer heat from IT equipment. Without proper treatment, impurities cause corrosion, scale, and biofouling that reduce heat-exchange efficiency and equipment life. Poor water management can lead to higher operating costs, unplanned shutdowns, and compliance risks.
Common Water Quality Challenges
- High total dissolved solids and hardness
- pH imbalance and corrosion potential
- Microbiological growth, including Legionella
- Suspended solids and fouling from airborne dust
- Variable water quality between make-up, blowdown, and reuse streams
Treatment Techniques
Effective water treatment in data centres focuses on maintaining consistent water chemistry across make-up, recirculating, and blowdown streams. The goal is to protect cooling infrastructure, reduce water consumption, and maximise thermal efficiency. Treatment systems are designed for reliability and redundancy, with automated monitoring and control to maintain stable operation under varying load and environmental conditions.
- Filtration to remove suspended solids and debris
- Chemical dosing for pH, corrosion, scale, and microbial control
- UV or ozone disinfection to control bacteria and biofilm
- Side-stream filtration to maintain clean cooling-loop water
- Reverse osmosis or softening where high-purity make-up water is required



No operations and processes are identical, and as such, we believe in the importance of tailored solutions. We work closely with each operation to develop optimised treatment solutions that are uniquely designed to suit site conditions and operational needs.
Best Practices
Implementing best practices ensures long-term reliability and efficiency of cooling systems. A proactive approach to monitoring and maintenance prevents scaling, corrosion, and biological fouling before they impact performance. Data-driven insights from continuous monitoring help operators adjust treatment programs in real time, maintaining compliance and extending equipment life.
- Continuous monitoring of key water-quality parameters
- Routine maintenance and cleaning of cooling systems
- Periodic review of treatment programs and chemistry
- Partnering with experienced water-treatment specialists for tailored design
Hydroflux Expertise
Hydroflux designs and builds complete systems for make-up, side-stream, and blowdown treatment, including filtration, chemical dosing, and remote monitoring. Our stainless-steel skids are modular and scalable, suited for staged expansion and redundancy requirements typical of data-centre operations.
