Why Data Centers May Require RO or DM Water

Data center cooling systems are designed for continuous operation. Water quality therefore becomes an important part of long-term facility management.

1. Control of Scaling

Hardness-forming minerals can precipitate on heat-transfer surfaces and pipelines.

Scaling may reduce heat-transfer performance and increase cleaning requirements.

RO and appropriate pretreatment can significantly reduce the concentration of many scale-forming dissolved constituents.

2. Improved Cooling-System Performance

Clean makeup water helps maintain the intended operating conditions of cooling equipment.

Water chemistry still needs to be managed according to the cooling-system design, cycles of concentration and chemical-treatment program.

3. Reduced Mineral Deposition

Low-TDS treated water can help reduce the mineral load entering cooling systems.

This can be particularly useful where the raw-water quality contains elevated hardness or dissolved solids.

4. Better Control of Water Chemistry

A properly designed treatment system provides a more predictable water quality than untreated source water.

This makes it easier for facility operators to manage cooling-water chemistry.

5. Protection of Downstream Equipment

Heat exchangers, piping, valves, pumps and associated equipment can benefit from appropriately controlled water chemistry.

Water treatment does not replace corrosion-control or cooling-water chemical-management programs, but it can form an important part of the overall strategy.

Enviro RO DM Plant for Data Centers

Enviro develops water-treatment systems according to the application rather than supplying a single standard configuration for every project.

A data center in Bengaluru may have very different feed-water characteristics from a facility in Hyderabad, Mumbai, Chennai, Delhi, Pune or another location.

Therefore, the treatment plant should be designed around actual site conditions.

Typical design considerations include:

• Raw-water source
• Feed-water TDS
• Hardness
• Alkalinity
• Silica
• Iron
• Manganese
• Turbidity
• pH
• Chlorine
• SDI
• Required treated-water quality
• Required flow rate
• Daily operating hours
• Peak water demand
• Cooling-system requirements
• Storage capacity
• Installation area
• Automation requirements
