Ultrapure water systems utilize methods such as pretreatment, reverse osmosis technology, ultrapurification treatment, and post-treatment to almost completely remove conductive media from water, as well as reduce colloidal substances, gases, and organic materials that do not dissociate to very low levels. Ultrapure water systems are also known as: ultrapure water units, ultrapure water equipment, ultrapure water instruments, ultrapure water systems, and laboratory ultrapure water units. The resistivity of the ultrapure water produced by these systems should generally be greater than 10 megohms; water with a resistivity above 10 megohms is considered ultrapure water. High-quality ultrapure water can achieve a resistivity of 18.25 megohms.

Laboratory ultrapure water systems are broadly divided into four units: pretreatment, reverse osmosis, ion exchange, and terminal ultrafiltration. Tap water first passes through the pretreatment unit to remove larger particles, suspended solids, and some organic matter. It then enters the reverse osmosis unit, which intercepts and removes ionic substances and macromolecular substances (such as viruses, microorganisms, etc.). Afterwards, it goes through the ion exchange unit to purify and ultrapurify the residual trace ions left after membrane treatment, reducing the ion content in the water to trace levels. Finally, technologies such as UV and ultrafiltration ensure that the microorganisms, organic matter, and pyrogens in the ultrapure water meet the requirements of various laboratory applications.

Technical Requirements

1. Two-stage reverse osmosis for deep desalination, with feed water quality <2000μs and hardness <450ppm;

2. Reverse osmosis purified water meets the GB6682-2008 Grade 3 water standard, while ultrapure water exceeds the GB6682-2008 Grade 1 water standard.

3. System desalination rate ≥99.5%, with a feed water to wastewater ratio of 1:3.

4. Features self-diagnosis for operational abnormalities (water quality and quantity of feed water, pre-purified water, and ultrapure water), with alerts or automatic system shutdown.

5. Intelligent fault detection (online replacement indicators for key system components: solenoid valves, booster pumps, UV lamps, sensors, etc.).

Product Features

1. Equipped with a complete purification unit, it takes tap water as input and produces pure water and ultrapure water as output. It generates water of different standards to meet the water needs of various laboratories.

2. The new laboratory ultrapure water system produces 40 times more ultrapure water per unit than similar imported products, with a water production cost one-fiftieth of other products.

3. If the feed water quality is less than 2000μs and hardness ≤450ppm, the system can stably produce water with a quality below 5μs/cm, and feed water utilization can reach 60%-80%.

4. Users can also quantitatively draw pure water and ultrapure water. By setting the desired volume, the ultrapure water system automatically produces the appropriate amount of water. The draw volume can be freely set from 10 milliliters to 200 liters, with quantitative accuracy within ±2ml.

5. Users can store and query data in real-time through the fully intelligent monitoring system, enabling trend analysis. The system supports multiple languages and multiple users, with separate data recording.

6. Features a true-color LCD touchscreen with a graphical human-machine interface, allowing one-step operation and online information query. All system monitoring data is collected in real-time and can be viewed online without external computer storage. Data storage capacity exceeds one year.

7. The rational placement of consumables in the purification unit and the plug-and-play design of components make calibration, maintenance, cleaning, disinfection, and sampling during system validation easier to perform.
