The Water
Layer for
半導體
The most comprehensive water management solution for semiconductor manufacturing
Ultrapure water, wastewater reuse, and zero liquid discharge, engineered and delivered as one accountable system across the entire fab.
Water determines
go / no-go
Water is now the deciding factor in whether a fab gets built. For the most advanced nodes, water has stopped being a utility line item and has become a condition of production, as strategic as power and land. The fabs that solve water early move faster and run with greater certainty.
One accountable partner managing the water layer
Most fabs rely on a patchwork of vendors, each responsible for a single piece and none for the result. Gradiant takes the whole layer. We engineer reuse and discharge as one performance system, and we can operate it for the life of the plant.
One partner. One number to call. One result we stand behind.
Highest system recovery
We cut freshwater intake to the minimum a site can run on, with system-level water reuse above 90 percent. Less water in, less risk, lower cost over the life of the plant.
Purity that holds
We maintain ultrapure spec even as feed water shifts, and remove contaminants others leave behind, from PFAS to azoles. Purity for the nodes shipping today and the ones coming next.
Any model, delivered
Design and build, design and supply, or fully owned and operated. Turnkey or equipment only. We tailor our offer to each fab’s capital preference.
Globally proven
We deliver wherever sites are being built. Our worldwide team has completed installations for chip foundries across the United States, Europe, India, Taiwan, Singapore, and Japan.
One end-to-end solution, solving three challenges
across the fab.
What semiconductor leaders know us for is delivering high water reuse within a fab. We take a plant’s incoming water requirement and drive it down to a fraction of what it would otherwise be, recovering and returning water at every stage. That outcome is built from three connected capabilities.
Ultrapure water (UPW)
Deliver the purity the most advanced nodes demand, and hold it even as source water changes. Backed by the legacy of H+E, the team that delivered the largest chip-foundry ultrapure water plant in Europe.
Wastewater treatment and reuse (WWT)
Concentrate and recover the many distinct streams a modern fab produces, each with its own chemistry and toxicity, separately or combined, at high recovery. This is our core discipline. We are concentration experts, turning complex wastewater into reusable water at scale.
Zero liquid discharge (ZLD)
Close the loop at the end of the process, converting discharge into reusable water and recoverable solids. Increasingly required for permitting in many regions.
Built around how your fab
contracts, builds, and operates
Every project has a different delivery model. Gradiant adapts to the commercial and execution structure of each fab, from turnkey delivery to equipment supply to build-own-operate.
Design and build
We lead engineering, installation, commissioning, and startup.
Design and supply
We provide the engineering and technology so your team can execute.
Build-own-operate
We put the capital down, deliver the equipment, and operate the water layer to contracted performance standards day in and day out.
Ultrapure water
The challenge is not just purity. It is maintaining purity while the source water varies. As feature sizes shrink toward the scale of a single hydrated ion, tolerance requirements are measured in parts per quadrillion. Gradiant maintains this precise spec no matter the feed water, a critical capability for consistent fab output.
Selective
Contaminant
Extraction
SCE targets specific hard-to-remove contaminants so a wider range of feedwaters can be treated to exact cooling water objectives.
Cure
化学品
Customized chemical programs help control scale, corrosion, and biofouling in cooling systems to improve heat transfer and thermal efficiency.
Smart哦ps
Monitors, predicts, and optimizes water systems in real time, improving reliability, reducing downtime, and lowering operating costs.
Wastewater
treatmenT and reuse
A modern fab produces many distinct wastewater streams, each with its own chemistry. We treat them at high recovery, individually or co-mingled, and return clean water to the plant. Emerging contaminants like PFAS and azoles are removed and permanently destroyed, with membranes, micro-foam fractionation, and electro-oxidation.
Semi-Batch
REVERSE
OSMOSIS
SBRO is a high-recovery reverse osmosis process that helps recover more water, reduce energy use, and cut brine volume while maintaining reliable performance on variable feedwater.
COUNTER
FLOW
REVERSE
OSMOSIS
CFRO enables ultra-high water recovery and brine concentration, minimizing liquid discharge, reducing waste volumes, and lowering disposal costs for data center operations.
BIO INFINITY
Strips biodegradable organics like IPA, ammonia, and BOD from wastewater with high-rate biological treatment, holding discharge limits
Zero liquid discharge
At the end of the process, we convert what remains into reusable water and solids, so the site sends out as little as possible. That is what lets a plant meet the discharge commitments tied to permitting and public funding.
CARRIER GAS EXTRACTION
Carrier Gas Extraction uses thermal evaporation to concentrate brine, recover water, and minimize liquid discharge and waste in data center operations.
COUNTER FLOW REVERSE OSMOSIS
CFRO enables ultra-high water recovery and brine concentration, minimizing liquid discharge, reducing waste volumes, and lowering disposal costs for data center operations.

FREQUENTLY ASKED QUESTIONS
Why is water critical to semiconductor manufacturing?
Advanced fabs depend on large volumes of ultra-clean water to operate reliably. Water affects site selection, permitting, public funding, production certainty, and long-term operating cost. For leading-edge fabs, water has become a condition of production.
What does Gradiant mean by “the water layer” for semiconductors?
Gradiant manages the full fab water system as one integrated layer, from intake and ultrapure water to wastewater reuse and zero liquid discharge. Fabs can work with one accountable partner responsible for system-level performance.
How does Gradiant help fabs reduce freshwater demand?
Gradiant designs systems to recover, treat, and reuse water across the fab, reducing the freshwater a site needs to operate. Our systems are engineered for greater than 90 percent system-level water reuse, helping fabs lower water risk, improve site resilience, and reduce lifecycle cost.
Can Gradiant meet the purity requirements of advanced semiconductor nodes?
Yes. Gradiant delivers ultrapure water systems built to maintain spec as source water quality changes and node requirements advance. Our systems are engineered to hold purity consistently through variability in feed water, operations, and fab demand.
Can Gradiant treat complex semiconductor wastewater, including PFAS and azoles?
Yes. Semiconductor fabs produce many wastewater streams with distinct chemistries. Gradiant treats these streams individually or combined, recovers water for reuse, and addresses difficult contaminants such as PFAS and azoles. Where required, Gradiant can also support zero liquid discharge to reduce discharge risk and help meet permitting requirements.
