Industrial Glass Cleaning Pure Water Equipment Solutions | Qingqingquan Professional Manufacturer

 In the glass manufacturing and cleaning industry, water quality directly affects the cleanliness and final quality of the product surface. If ordinary water is used for cleaning, water stains, minerals and impurities are easily left on the surface of glass, resulting in decreased light transmittance, uneven coating and other problems.

 For this reason, Qingqingquan focuses on the research and development of industrial pure water equipment, providing from 0.25T/H to 100T/H of the first class reverse osmosis (RO) water system and ultrapure water solutions to ensure that the glass cleaning to meet the high standard requirements.

I. Water quality standard of glass washing water

Different application scenarios have different requirements for water quality:

1.1 General glass cleaning

 • Conductivity requirements: ≤10µS/cm (a reverse osmosis pure water can meet)

 • Applicable scenes: architectural glass, furniture glass, automobile glass, etc.

1.2 Coated glass, optoelectronic industry (LED/LCD/Liquid Crystal Display)

 • Resistivity requirements: the highest need to reach 18MΩ.cm (ultrapure water)

 • Conformity standard:

    1. U.S. ASTM pure water standards

    2.China Ministry of Electronics Industry electronic grade water quality standards

    3. Japan integrated circuit water quality standards

II. Qingqingquan pure water equipment process

1. A reverse osmosis system (ordinary glass cleaning)

for conductivity ≤ 10µS/cm cleaning needs, the process flow is as follows:

Raw water tank → raw water booster pump → sand filter → carbon filter → water softener → precision filter → high-pressure pump → one-stage reverse osmosis (RO) → pure water tank → water point

Features:

 • Highly efficient removal of particles, colloids, organic matter and ionic impurities in water.

 • The water production capacity of the equipment covers 0.25T/H~100T/H, and supports customization.

2. Ultra-pure water system (Optoelectronics/LED/LCD industry)

Adding EDI (electrodeionization) or mixed-bed polishing on the basis of one-stage RO, the water quality can reach 18MΩ.cm to meet the needs of high-end manufacturing.

III. Why choose us?

1. Industry specialization: years of experience in industrial water purification equipment, mature and reliable technology.

2. Flexible customization: from small laboratory equipment (0.25T/H) to large production lines (100T/H) can be designed.

3. Compliance Guarantee: The water output of the equipment meets international standards.

4. Ongoing service: Provide installation and commissioning, maintenance training and consumables replacement support.

IV. Frequently Asked Questions

Q1: Does the primary RO water purification equipment need a water softener?

A: Yes. When the raw water hardness is high, the softener can prevent the RO membrane from scaling and extend its service life.

Q2: What is the running cost of the ultrapure water system?

A: The ultrapure water system needs additional EDI or mixed bed module, the initial investment is higher, but the long-term running cost is lower than the traditional mixed bed (reduce acid and alkali consumption).

Q3: How long is the equipment maintenance cycle?

A:  • Sand filter / carbon filter: 3-6 months to replace the filter media

    • RO membrane: 2-3 years replacement (depending on the quality of incoming water)

    • EDI module: more than 5 years life

V. Applicable industries and customer cases

1. Glass processing factory: solve the problem of water marks and white spots after cleaning.

2. Optoelectronic enterprises: to ensure that the coated glass, liquid crystal screen without impurity pollution.

3. Laboratory: provide stable small flow of ultrapure water.
