Increase Cooling Cycles, Reduce Water Draw, and Recover Blowdown Water
Saltworks helps operators reduce water consumption without sacrificing energy performance. By treating and recycling cooling tower blowdown, data centers can lower make up water demand by roughly 40 percent while maintaining efficient evaporative cooling.
Our engineered systems stabilize water chemistry, increase cooling tower cycles, and return recovered water to the process, improving both performance and operating economics.
Saltworks uses a staged water treatment and recovery approach tailored to site economics and recovery targets:
Water is first pre‑conditioned to remove suspended solids and organics, including azole‑based corrosion inhibitors that would otherwise foul downstream membranes. Saltworks delivers this step using filtration solutions and Xtract absorption vessels. Once conditioned, lower pressure XtremeRO recovers most of the freshwater until silica or sulfate scaling limits are reached, typically achieving about 80 percent recovery.
If silica or calcium sulfate begin to constrain recovery, BrineRefine and XtremeUF remove these ions to unlock further concentration. High‑pressure XtremeRO then pushes recovery toward approximately 98 percent. The remaining 2% becomes a small brine volume that can be discharged where allowed or hauled off‑site if disposal is restricted.
For sites without brine disposal options, SaltMaker Crystallizers convert the final concentrated brine into solid salts, eliminating liquid waste entirely. This step maximizes water reuse and ensures complete control over cooling system discharge.
This approach has been validated on large data center cooling systems and supports up to approximately 40 percent reduction in make up demand when recycling blowdown.
Saltworks solutions are designed for data center reliability, scale, and chemistry. We provide:
Our treatment systems help operators reduce water draw, maintain efficient cooling, and improve overall system performance.
Saltworks’ engineers work with global data center operators to evaluate site chemistry, recovery potential, and economic trade‑offs. We help you reduce water consumption while keeping evaporative cooling efficient and reliable.

BrineRefine is a continuous stirred tank reactor (CSTR) that executes diverse chemical reactions efficiently and with precision.

Our XtremeRO and FusionRO provide industry-leading recovery and reliablity. Concentrate brine, reduce discharge volumes, recover freshwater and more.

Saltworks solves cooling tower blowdown challenges. We can help you reduce water usage and protect your assets by treating inlet water or recovering water from blowdown. We study your problem to help you optimize costs, recover water, and explore brine management strategies.

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.

Reverse osmosis-based brine concentrators are reaching new performance levels not seen before. Saltworks is pleased to report that a substantial pilot plant is currently demonstrating 99% freshwater recovery on cooling tower blowdown (CTB).

A full-scale, waste heat-driven, Saltworks evaporator has been delivered to an electric vehicle (EV) battery plant. The SaltMaker AirBreather evaporator will treat a highly saline wastewater stream to reduce its volume, reducing the client’s need to truck wastewater offsite.
