Overview
ARBOK-Light Water is a specialized water production process that removes deuterium (heavy hydrogen, ²H) from ordinary water, producing ultra-pure H₂O with deuterium concentration reduced substantially below natural background levels. Achieves isotope separation using ARBOK-VC vacuum-based phase separation technology. Light water (deuterium-depleted) has applications in pharmaceutical research, high-precision analytical chemistry, and specialized industrial processes where trace deuterium interferes with results. Complements ARBOK-Deuterium (heavy water production) as inverse process.
Applications
Primary use cases: pharmaceutical R&D; medical research (deuterium-sensitive biomarkers); analytical chemistry (NMR, mass spectrometry); specialized cosmetics; high-purity industrial solvents.
Industries and users: pharmaceutical companies, research institutions, analytical laboratories, specialty chemical manufacturers.
Scale: laboratory scale (liters/day) to pilot production (tons/year).
Operating Principle
Natural water contains a small natural background level of deuterium (heavy water, D₂O mixed with H₂O). ARBOK-VC operates under vacuum, at ambient temperature — equal to the incoming feed and surroundings, with no external heating — to selectively evaporate and separate H₂O from D₂O based on subtle differences in boiling-point depression and mass. Multiple stages concentrate either light water (H₂O enriched, deuterium depleted) or heavy water (D₂O enriched). Output: light water with deuterium reduced well below natural levels.
Key Parameters
Deuterium content: reduced substantially below natural background levels through multi-stage processing.
Purity: very high H₂O purity, verified by mass spectrometry.
Throughput: 100 L/day laboratory to 10 t/year pilot scale.
Energy: low specific energy consumption, comparable to the broader ARBOK-VC platform baseline.
Isotope separation factor: favorable multi-stage separation performance, consistent with established vacuum isotope-separation methods.
Consistency: reproducible isotope ratios; quality verified via mass spectrometry.
Architecture and Components
Multi-stage vacuum evaporation chamber; fractionation columns; condensation/separation system; isotope monitoring (mass spectrometry quality control); thermal management. Modular, scalable from lab to pilot.
Advantages
Technical: isotope-selective separation without chemical additives; high purity; scalable; complements heavy-water production (ARBOK-Deuterium).
Economic: lower cost than alternative isotope-separation methods (thermal diffusion, electrolysis); enables specialized research previously cost-prohibitive.
Environmental: zero chemical discharge; energy-efficient vs. competing isotope technologies.
Research: enables new pharmaceutical/biomedical research pathways; supports analytical chemistry precision.
Integrations
Paired with ARBOK-Deuterium (produces both light and heavy water fractions); integrates with laboratory/analytical chemistry workflows; supports specialized water supply chains.
Deployment & Operation
Steps: feedwater source → isotope analysis → multi-stage vacuum processing → light-water collection → isotope verification (QC) → delivery to customer. Automated batch or continuous operation.
TRL
TRL 5 — Validated in relevant environment. Laboratory and pilot-scale isotope-separation runs completed; light-water isotope purity verified; scalability confirmed. Ready for commercial pilot production and research partnerships.
Market Potential
Niche but high-value market: pharmaceutical R&D, advanced research institutes, specialty chemistry. Estimated: €5–20M/year global market for high-purity light water and deuterium-sensitive applications.
Typical Project Economics
CAPEX: €100k–500k per pilot production unit. OPEX: €5–15/L production cost (depends on scale). Selling price (research grade): €50–150/L. Margin: 70–80 % at scale. Payback: 2–4 years for pilot unit.
Risk Factors
Small niche market (pharma/research only); regulatory compliance (isotope labeling, purity certification); customer qualification (must validate light-water necessity); long sales cycles (academic/pharma procurement).
