Product introduction

1、Definition and standard of ultrΩ≤a-pure water machine

Ultrapure Water (UPW) ​↓≤ Ultrapure water (UPW ♦¥♦) ** refers to high-pu→&rity water with a res©β✔istivity ≥18.2 MΩ·cm (25 ° C), to×★tal organic carbon (TOC) ≤5 ppb, an×ε©d particulate matter ≤1 /mL, almo÷φ¶st free of ions, microorganisms, and or™≠ganic matter.

2、Core process and equipment comλ∞♣position

Pretreatment system:

Multi-media filter: rem '©§oval of suspended solids, colloi >£✔ds.

Activated carbon filter: adsorpt®¥ion of residual chlorine, organic ma‌™→tter.

Softener: removes calcium and magnesiu​™m ions (anti-scaling).

Reverse Osmosis (RO) ★♣↑systems:

97%-99% of the ions and φ∏organic matter are removed,  ₹and the conductivity of the produceδ←γ♥d water is less than 10 μS/c×γ₽m.

Electrical deionization (EDI) systemsδ$♣:

Further purificationαφ™ to a resistivity ≥15 MΩ·cm ↔₹was achieved by ion-excδ£hange membrane and electδΩric field.

Post-processing system:≥¶λ

Ultraviolet sterilization (UV) ¶≥λ∞: Inactivates microorganisms.

Ultrafiltration (UF) : re→→$moval of pyrogen, nanoscale particl♠Ω¥es.

Polishing mixed bed: ​ ↕final purification, up to 1γ™8.2 MΩ·cm.

5、Selection and maintenance ≥ '>suggestions

Key points of selection:

Water quality requirements: The semic₹£€₽onductor industry needs 18.2 MΩ·cm, β the pharmaceutical industry can re¶§δ>lax to 15 MΩ·cm.

Water yield: +20% redund∑→ancy based on peak water consum←¶¥λption of production line.

Energy consumption: High efficie®≈±ncy RO membrane and low eφ&₹nergy EDI module are preferred.

Maintenance:

Daily: Check the pressure, flow, an€≥λ¥d conductivity parameters an>≈d record running logs.

Monthly: Clean the RO membrane (chemi•λ$ cal cleaning or reverse washing) an♦↑d replace the pretreatment filter eleme∞←​nt.

Annual: EDI module ion exchange resin☆<→ replacement, sensor calibratiλ↕  on.

6、Common problems and solutions

Problem cause analysis solutio®₩ ≈n

The particle settling stirring↑  speed is insufficient ×σ×εor the time is too short to increase t★∑↑he rotational speed an→€&d prolong the stirring time"♥

Temperature fluctuation large jacket me'® dium uneven flow check pump£ε valve, adjust flow

Seal leakage seal ring agin‍π×g or improper installation Replace t♣ ÷he seal ring, recalibrate✘¥ the shaft

Motor overheating load is too larε★≈ge or poor heat dissipation reduce t™↔ he speed, clean the heat dissipatio€→'n fan

7、Technological development trends

Intelligent: The Internet of Thing φs (IoT) monitors water quality in≈÷ real time, and AI predicts ←↕↕≤membrane life.

Green energy saving: Devγ₹×elop low waste liquid dis♠$→charge process, improve water   ¥¶recovery rate to more than 90%.

Integration: Ultra-pure water equi §↔pment is directly coupled to the pro←₽<₽duction line to reduce the risk♦∑​ of water pollution.
