Overview
The SFT SCWO Series Supercritical Water Oxidation Systems are engineered for rigorous laboratory and pilot-scale research into the complete mineralization of organic contaminants in aqueous waste streams under supercritical water conditions (T > 374 °C, P > 22.1 MPa). These systems operate on the principle of supercritical water oxidation (SCWO), where water transitions into a dense, nonpolar fluid phase with enhanced solvation capacity for organic compounds and full miscibility with oxygen—enabling rapid, near-complete (>99.99%) oxidation of recalcitrant organics—including pharmaceuticals, pesticides, chemical warfare agent simulants, and complex biological effluents—without producing NOx, SOx, or solid residues. Designed for NASA-relevant life-support R&D, the SCWO platforms simulate closed-loop wastewater reclamation for long-duration space missions, achieving potable water quality per NASA STD-6001B and EPA Method 1681.
Key Features
- Three scalable configurations: SCWO-100 (100 mL reactor, no oxidant injection), SCWO-250 (250 mL reactor, dual H2O2/O2 delivery), and SCWO-1000 (1000 mL Inconel 625 reactor, full oxidant flexibility and thermal mass stability)
- PID-controlled temperature regulation from ambient to 500 °C (±0.5 °C accuracy) across reactor, preheater, and backpressure zones
- High-integrity pressure management up to 10,000 psi (68.9 MPa), with redundant pressure transducers and fail-safe rupture disc assemblies compliant with ASME B31.3 process piping standards
- Dual high-pressure metering capability: digitally controlled plunger pump for deionized water (0–100 mL/min) and precision diaphragm pump for concentrated H2O2 (0–24 mL/min @ 6000 psi)
- Integrated gas handling: oil-free diaphragm compressor (500 NL/h O2 or air), thermal mass flow controller (0–500 NL/h, ±1% FS), and pressure-regulated gas injection manifold
- Multi-stage thermal management: tubular electric preheater (300 mL, PID-controlled), shell-and-tube condenser (300 mL, 500 °C max inlet), and ON/OFF-cooled heat exchanger for post-reaction quenching
- Automated safety interlocks including overtemperature cutoff, pressure deviation alarm, coolant flow monitoring, and emergency depressurization valve activation
Sample Compatibility & Compliance
The SCWO Series accommodates heterogeneous feedstocks including raw municipal wastewater, pharmaceutical manufacturing effluent, algal biomass digestate, and simulated spacecraft hygiene water containing surfactants, urea, amino acids, and trace antibiotics. All wetted components conform to ASTM A240 (stainless steels), ASTM B443 (Inconel 625), and NACE MR0175/ISO 15156 for sour service resistance. System validation supports GLP-compliant operation per OECD 117 and USP <621> for method transfer. Data acquisition meets FDA 21 CFR Part 11 requirements when paired with optional audit-trail-enabled software modules.
Software & Data Management
Control is executed via SFT’s proprietary SCWO Control Suite—a Windows-based application supporting real-time parameter logging (temperature, pressure, flow rates, valve positions) at 10 Hz sampling. The suite enables programmable ramp-hold profiles, multi-step oxidant dosing sequences, and automated shutdown protocols. Raw data exports to CSV and HDF5 formats; time-synchronized logs integrate seamlessly with third-party LIMS (e.g., Thermo Fisher SampleManager, LabVantage) and statistical analysis tools (MATLAB, Python Pandas). Optional 21 CFR Part 11 compliance package includes electronic signatures, role-based access control, and immutable audit trails with SHA-256 hashing.
Applications
- Aerospace wastewater reclamation R&D for ISS and Artemis lunar surface systems
- Regulatory method development for persistent organic pollutant (POP) destruction per Stockholm Convention Annexes
- Pharmaceutical QC/QA: validation of active pharmaceutical ingredient (API) degradation kinetics under hydrothermal oxidative stress
- Defense environmental remediation: neutralization of energetic materials (RDX, HMX) and fluorinated surfactants (PFAS)
- Academic catalysis studies: evaluation of heterogeneous catalysts (e.g., MnO2/CeO2) for subcritical-to-supercritical transition zone optimization
- Microplastic fragmentation and mineralization kinetics in synthetic seawater matrices
FAQ
What is the maximum allowable chloride concentration in feedwater before corrosion risk escalates significantly?
Chloride concentrations exceeding 1000 ppm require Hastelloy C-276 or Inconel 625 construction (standard on SCWO-250 and SCWO-1000); SCWO-100 (SS316L) is limited to ≤200 ppm Cl⁻.
Can the system operate continuously for >72 hours without maintenance intervention?
Yes—SCWO-1000 achieves 120-hour continuous runs with scheduled backflushing intervals; SCWO-250 supports 48-hour unattended operation with pre-conditioned feed streams.
Is real-time TOC or CO₂ measurement integrated?
No native TOC analyzer is included, but the system features standardized ¼″ VCR ports for inline FTIR (e.g., Gasmet DX4000) or NDIR CO₂ sensors compatible with ASTM D7575 workflows.
Does SFT provide installation qualification (IQ) and operational qualification (OQ) documentation?
Yes—factory-verified IQ/OQ protocols aligned with ISO/IEC 17025 and ASTM E2500-07 are supplied with each system, including calibration certificates for all critical transducers.
What training options are available for operators and maintenance personnel?
SFT offers on-site commissioning support, 3-day hands-on operator certification, and annual refresher courses covering preventive maintenance, failure mode analysis, and emergency response drills.
