CliniWater positions the Portable Dialysis Unit and Portable Lab Water Unit as the core purification assets. Each unit is housed in a ruggedized, wheeled case (IP65 rated) weighing under 35 kg. The Portable Dialysis Unit accepts raw water from any potable or clarified source and processes it through a 5 µm pre-filter, carbon block, single-pass RO membrane, and a battery of endotoxin-retentive ultrafilters, delivering 2 L/min of dialysate-grade water. The Portable Lab Water Unit adds dual-wavelength UV oxidation (185/254 nm) and a 0.05 µm absolute filter to produce Type I ultrapure water (18.2 MΩ·cm) for point-of-care testing and field lab use. Both units operate on 110–240 VAC, 50/60 Hz, with an optional 24 VDC input from vehicle batteries.

Technical Note: The RO membrane in the portable dialysis unit must be flushed with permeate for 5 minutes after every use to prevent biofouling during storage. If deployed infrequently, store the membrane in a 1% sodium bisulfite preservative solution.

The Portable Dental Water Unit provides up to 3 L/min of purified water (< 10 µS/cm) for emergency dental procedures. The unit’s internal 20 L collapsible reservoir can be filled from any available water source; the purification train (sediment filter, carbon, RO, UV) recirculates until the target conductivity is reached. For areas where source water is scarce, a Dental Water Distiller powered by a portable generator provides 8 L/h of distilled water. A Handheld Conductivity Meter and a pH Meter are issued with every unit to verify output quality; the team logs readings at the start of each clinical session.

Technical Note: The distiller requires 30 minutes to reach steady-state production after power-on. Pre-heating the boiling chamber with hot source water reduces startup time by 40%. Descale the boiling chamber every 50 cycles using food-grade citric acid.

All mobile water units are accompanied by an IP67 transport case containing essential QC instruments: a Handheld Conductivity Meter with automatic temperature compensation, a pH Meter with flat-surface electrode for low-volume samples, a Hardness Test Kit (drop-count titration), and a Total Chlorine/pH Test Kit (DPD colorimetric). For higher analytical demands, a Laser Particle Counter provides rapid quantification of particulate contamination in the 0.5–25 µm range, invaluable for verifying filter integrity after transport. A UV Spectrophotometer configured for absorbance at 254 nm estimates organic contamination as a surrogate for TOC, using a pre-loaded calibration curve.

Technical Note: The Laser Particle Counter’s sample inlet must be capped when not in use to prevent dust ingress. Purge the instrument with particle-free water for 60 seconds before taking a measurement; omit this step and the first reading will be artifactually elevated.

CliniWater provides a compact training module delivered via a ruggedized tablet, covering: (1) source water classification using the Hardness Test Kit and Total Chlorine/pH Test Kit; (2) selection of the appropriate purification train based on water quality; (3) system priming and air-bleeding; (4) QC acceptance criteria for clinical use. A laminated decision matrix in the lid of each transport case guides the operator: if hardness > 200 mg/L as CaCO₃, add an ion-exchange Softener Cartridge; if chlorine > 2 mg/L, install a second carbon block. Teams practice setup and QC verification within a target time of 20 minutes.

Technical Note: In cold environments (< 5 °C), the portable units’ RO membranes lose permeate output significantly. Position the unit inside a heated tent or enclosure. The control module has a low-temperature safety lock that prevents pump operation below freezing to avoid ice damage.

Each mobile unit is equipped with a satellite-enabled data logger that transmits water quality parameters (conductivity, temperature, particle count) and GPS coordinates to a cloud-based fleet management portal accessible to the home-base logistics team. The portal displays the operational status of all deployed assets on a world map, with automated alerts for missed QC checks. Treatment logs are synchronized when connectivity is restored, providing auditable documentation for medico-legal and humanitarian reporting requirements. An on-board printer generates a patient-ready water quality report for attachment to clinical records.

Technical Note: The data logger’s internal battery supports 72 hours of operation without external power. Configure the transmission interval to 15 minutes to conserve satellite bandwidth; critical alarms (conductivity > 10 µS/cm dialysis) transmit immediately regardless of the interval.
