Reclaimed water, delivered as a service
Cooling towers generate blowdown water that is typically discharged, increasing water consumption and operational costs. At the same time, industries face growing pressure to improve water efficiency and resilience.
Kurita’s Cooling Tower Blowdown Recovery System enables the recovery and reuse of blowdown water through an integrated, service‑based approach, transforming wastewater into a reliable source of reclaimed water while reducing investment risk.
Why is Water Revalorization Important?
Infrastructure upgrades and stricter regulatory compliance.
Higher costs for sourcing and treating water, combined with tighter regulations.
Increased compliance costs and potential penalties ce
Impact of energy prices on water treatment and cooling system efficiency
Opportunities to improve water and energy efficiency while reducing consumption

Water Reclaimed Supply Service - Expert Q&A
A reclaimed water supply service transforms industrial wastewater – specifically cooling tower blowdown – into high-quality reusable water. Instead of discharging this stream, it is treated and safely retured to the cooling system, reducing freshwater intake and wastewater discharge.
Cooling towers typically account for up to 40% of a facility’s total water consumption. Blowdown is a concentrated stream that represents a major opportunity for water savings. Treating blowdown delivers higher water, energy, and cost savings than treating make-up water.
Water valorization helps facilities remain operational despite water scarcity, climate variability, and regulatory pressure. By reducing dependence on external water sources, plants improve water resilience and protect production continuity.
Key benefits include reduced freshwater consumption, lower wastewater discharge, improved sustainability performance, better return on investment, and increased autonomy from local water constraints.
Blowdown water is more concentrated and has higher fouling, scaling, and corrosion potential. Successful reuse requires advanced water chemistry management, tailored pretreatment, membrane protection, and continuous operational control.
By combining cooling water expertise with membrane treatment know-how, including optimised chemistry, advanced filtration and reverse osmosis design, and continuous monitoring.
The Kurita’s reclaimed water supply service is delivered as an OpEx-based model, avoiding large upfront investments and ensuring guaranteed long-term performance.
Through detailed upfront analysis, digital monitoring of KPIs, preventive maintenance, and continuous optimisation.
Yes. Seasonal variations in water quality and operating conditions are considered during design and continuously managed during operation.
Any industry using cooling towers, including petrochemical, chemical, food & beverage, power generation, and general manufacturing.
No, not with proper design. Pre-treatment, anti-fouling strategies, and routine maintenance keep membranes running efficiently for long periods.
No. It improves quality but doesn’t reduce volume. Reuse is needed to cut overall water consumption.
