High purity water can effectively remove stains and small particles from the surface of the lens, Avoid introducing new contaminants during the cleaning process, Thus, the optical clarity and image quality of the lens are guaranteed.

3. Raw water quality and quantity

• Raw water type: Municipal tap water

• Water requirement: 1T/H (Omni hora 1 Tons of)

• Water quality test report: Although no specific water quality test report was provided, However, the quality of municipal tap water usually meets certain national or local standards, Such as "Standard for drinking water" GB5749-2022 Etc. however, In order to ensure the effectiveness of the subsequent treatment process, Some analysis and testing of raw water may still be required.

4. Water quality requirement

• Electrical resistivity: ≥15MΩ cm

• Other indicators: It might have to be considered pH value, Dissolved oxygen, Microbial content and other indicators, Specific according to the production process and product needs to determine. But in this case, Resistivity is the main indicator of concern, Because it directly reflects the purity of the water.

5. Water requirement

• Water consumption per hour of production: 1T/H

• Consider peak hours and backup requirements: A certain margin should be reserved when designing, To meet the demand for water during peak production hours or emergencies.

6. Device installation environment

• Access and distribution of water: Ensure that there are sufficient water pipes and interfaces in the construction site, Easy device connection.
