Gain in-depth understanding of the structure and processes of ultra-pure water system installations
Thread Content
Ultra-pure water preparation is one of the advanced water treatment devices developed and produced by Lightlead Shanghai Water Treatment Equipment Company. It boasts many advantages such as simple operation and a long service life, which has earned it great popularity among users. It usually consists of reverse osmosis units, ultrafiltration units, ion exchange units, EDI units, etc., meeting the water requirements in the electroplating industry. The use of ultra-pure water in the electroplating field can improve the surface finish, adhesion, and brightness of the plated parts. Process flow of ultra-pure water equipment:1. Pre-treatment system → Reverse osmosis system → Intermediate water tank → Coarse mixed bed → Fine mixed bed → Pure water tank → Pure water pump → UV sterilizer → Polishing mixed bed → Precision filter → Water user (≥18MΩ.CM) (Traditional process)
2. Pre-treatment → Reverse osmosis → Intermediate water tank → Water pump → EDI unit → Purification water tank → Pure water pump → UV sterilizer → Polishing mixed bed → 0.2 or 0.5μm precision filter → Water user (≥18MΩ.CM) (Latest process)
3. Pre-treatment → First-stage reverse osmosis → Chemical dosing machine (pH adjustment) → Intermediate water tank → Second-stage reverse osmosis (positively charged reverse osmosis membrane) → Pure water tank → Pure water pump → EDI unit → UV sterilizer → 0.2 or 0.5μm precision filter → Water user (≥17MΩ.CM) (Latest process)
4. Pre-treatment → Reverse osmosis → Intermediate water tank → Water pump → EDI unit → Pure water tank → Pure water pump → UV sterilizer → 0.2 or 0.5μm precision filter → Water user (≥15MΩ.CM) (Latest process)
5. Pre-treatment system → Reverse osmosis system → Intermediate water tank → Pure water pump → Coarse mixed bed → Fine mixed bed → UV sterilizer → Precision filter → Water user (≥15MΩ.CM) (Traditional process)
Ultra-pure water production is primarily used for water treatment in various industries; it enables the continuous and stable production of high-quality pure water without the need to stop operations for resin regeneration. At the same time, this ultra-pure water system has a compact structure, occupies little space, saving space, and also offers energy-saving advantages.
