Lab Pure & RO Water Purification System | 15-45 L/h Water Purifier Clever-Q15

Designed for trace organic and inorganic analytical laboratories, this low-TOC ultrapure water system transforms municipal tap water into two distinct water grades: Grade 3 reverse osmosis (RO) permeate and Type 1 (18.25 MΩ·cm) ultrapure water. Delivering 15 L/h of continuous RO water production and an instantaneous dispensing speed of 2.0 L/min, the unit provides dedicated purity for high-performance liquid chromatography (HPLC), liquid chromatography-mass spectrometry (HPLC-MS), gas chromatography-mass spectrometry (GC-MS), and total organic carbon (TOC) testing.

Seven-Stage Cascade Purification and Dual-Wavelength UV Oxidation

The internal fluid architecture integrates seven sequential purification stages:

• A sediment pre-filtration column (BCS-PP) traps rust, silt, and coarse suspended solids.

• Dual activated carbon modules (BCS-AC1 granular carbon and BCS-AC2 dense carbon block) remove free chlorine, trace organics, and colloids to prevent chemical oxidation of downstream membranes.

• A high-rejection 100 GPD reverse osmosis membrane rejects over 99% of dissolved inorganic ions, heavy metals, and organic compounds with molecular weights exceeding 200 Daltons.

• A dual-wavelength (185 nm & 254 nm) ultraviolet photolysis lamp oxidizes residual trace organics into ionizable species while sanitizing bacterial counts.

• A dual-connected ultrapurification polishing module (BC-UP) packed with nuclear-grade ion-exchange resins extracts residual traces to achieve 18.25 MΩ·cm resistivity at 25°C, heavy metal ion concentrations under 0.1 ppb, and TOC levels below 3 ppb.

• A point-of-use 0.2 μm terminal capsule filter (BC-TF-0.2μm) removes sub-micron particulates (< 1/mL) and bacteria (< 0.01 cfu/mL).

Intelligent Qualitative & Quantitative Dispensing

The system offers flexible manual dispensing alongside fully automated quantitative and qualitative volumetric control. Users can program precise dispensing volumes from 10 mL to 999,999 mL or define target resistivity thresholds from 0.1 to 18.25 MΩ·cm. If water in the delivery line falls below the set purity threshold, an automatic recirculation loop routes water through the polishing resin bed until resistivity meets analytical requirements before dispensing. The main interface displays real-time flow rate, cumulative volume, resistivity, water temperature, and built-in 12 L tank level.

Three-Way Online Monitoring and Comprehensive Data Traceability

Water purity is monitored by three independent online sensors: raw water conductivity, RO permeate conductivity, and ultrapure water resistivity, complete with automatic temperature compensation (0.1°C sensitivity, resistivity cell constant 0.01 cm⁻¹). Programmable threshold alarms alert users immediately if purity deviations, feed pressure drops, or consumable expiration limits occur. An internal chemical dosing system enables automated periodic sanitization of recirculation loops, dispensing valves, and water storage modules. All historical dispensing events, water quality data, alarms, and encoded consumable replacement logs are stored internally and exportable via an integrated USB Host port for regulatory audit compliance.

Frequently Asked Questions (FAQ)

1. What distinct water grades are produced by this system?

The unit features two dedicated dispensing outlets: one delivering Grade 3 RO pure water for basic washing and buffer preparation, and one delivering Type 1 ultrapure water (18.25 MΩ·cm, TOC < 3 ppb) for advanced instrument analysis.

2. Why is a dual-wavelength 185 nm and 254 nm UV lamp used in this model?

The 254 nm wavelength destroys microbial DNA to inhibit bacteria, while the high-energy 185 nm wavelength generates hydroxyl radicals that photolytically oxidize organic contaminants, driving TOC levels below 3 ppb.

3. What analytical techniques require this low-TOC ultrapure water quality?

Water from this system is recommended for high-performance liquid chromatography (HPLC), HPLC-MS, GC-MS, inductively coupled plasma mass spectrometry, and trace TOC analytical instrumentation.

4. How does the qualitative dispensing function ensure reliable water quality?

Operators can define an acceptable purity threshold between 0.1 and 18.25 MΩ·cm; if line water drops below this setting, the system automatically redirects water through the polishing loop until the threshold is met.

5. How does the quantitative volumetric dispensing feature operate?

Users can pre-set any target volume between 10 mL and 999,999 mL, allowing automated, unattended vessel filling with automated shut-off once the exact target volume is reached.

6. What parameters are tracked by the three-way online monitoring sensors?

The unit monitors feed water conductivity, RO permeate conductivity, ultrapure water resistivity, and water temperature in real time, displaying automated alerts if readings exceed programmed limits.

7. How does the internal recirculation loop prevent water stagnation?

The programmable internal recirculation periodically circulates water through the UV photo-oxidation chamber and polishing resin bed during idle periods, maintaining purity and preventing biofilm growth.

8. How does the full-pipeline chemical dosing disinfection system function?

The built-in disinfection system allows operators to run sanitizing agents through the entire fluid network, including the recirculation lines, water reservoir, and dispensing valves, to eliminate bacterial colonization.

9. How are consumable lifespans tracked and scheduled for replacement?

The system tracks operating hours, processed volume, and installation dates for each encoded cartridge, providing proactive visual warnings on the display before cartridges become exhausted.

10. What are the feed tap water quality requirements for optimal operation?

The system requires standard municipal tap water at 5°C to 45°C, 1.0 to 4.0 kgf/cm² pressure, and conductivity below 400 μS/cm (water feeds above 400 μS/cm should be paired with an external softening pre-filter).

11. How does the system export water quality and maintenance records?

Operational parameters, historical dispensing events, system alarm logs, and consumable service records can be exported directly to a standard flash drive via the integrated USB Host port.

12. What components are included in the standard instrument delivery package?

The package includes the main system unit, a complete set of initial consumables (PP, dual AC, RO membrane, dual-wavelength UV lamp, UP dual column, and 0.2 μm filter), a built-in 12 L pressure tank, and an installation accessory kit.
