15 TPH EDI Ultrapure Water System
I.Conception
Our 15T/H EDI features continuous regeneration. It uses electrolytic regeneration (no acid/alkali). Resin removes ions; H⁺/OH⁻ regenerate resin; constant power supply discharges ions, ensuring stable 15T/H output and low cost.
Water Treatment Process: Two-stage RO + EDI
Water Production Capacity: 15 tons/hour
Water Quality: Resistivity: 1 Ω·m to 18.2 Ω·m
Footprint: 80 square meters
Applications: In vitro diagnostic reagents, medical devices, pharmaceutical equipment, surgical instruments, ultrapure water for laboratories, and other water applications

Identify needs
Clarify the following issues, and you can determine the right equipment for you.
Water quality problems
Example 1: sediment exceeds the standard/scale / turbid water / microbial exceeds the standard/ heavy metal exceeds the standard/money Yu exceeds the standard, etc.
Water standard
Example 1:Softened water/pure water/ultra-pure water/iron and manganese removal/sediment removal/sterilisation, etc.
Daily Water Consumption
Example 1:Whether there is a concentrated water consumption period/water consumption time/peak maximum water consumption/hourly average water consumption
Conclusion Example
5 tonnes per hour water softening equipment.
3 tonnes per hour reverse osmosis water purification equipment
If you can't answer the above questions clearly?
1. Daily Water Consumption: Mail a bottle of water sample
2. Water Standard: Just tell me your industry.
3. Water Consumption: We can help you calculate the water consumption.
