20T/H Double-Pass RO + EDI + Mixed Bed Ultrapure Water Treatment System for Hungary

What is this system designed for?

This ultrapure water system is designed to produce high-purity water (up to 18.2 MΩ·cm) for use in battery manufacturing, particularly for applications requiring strict control of ionic and organic contaminants. It ensures stable water quality for electrode preparation, electrolyte formulation, and cleaning processes.

What purification technologies are included?

The system integrates three major purification stages:

Dual-Stage Reverse Osmosis (RO) – Efficiently removes up to 99% of dissolved salts, organics, and particulates.

EDI (Electrodeionization) – Continuously polishes RO permeate, eliminating residual ions without chemical regeneration.

Mixed Bed Ion Exchange (MB) – Provides final polishing to achieve the highest resistivity and ultra-low TOC levels.

What is the final water quality specification?

• Resistivity: ≥ 18.2 MΩ·cm @ 25°C
• TOC: ≤ 5 ppb
• Silica: ≤ 0.01 mg/L
• Bacteria: < 1 CFU/mL
• Particles (>0.2 μm): < 1/mL

What are the system’s main components?

• Raw Water Tank & Multi-Media Filter – Removes suspended solids and turbidity.
• Activated Carbon Filter – Adsorbs chlorine and organic impurities.
• Softener – Reduces hardness to protect RO membranes.
• Dual-Stage RO Unit – High rejection membranes with automatic flushing.
• EDI Module – Continuous ion removal without regeneration chemicals.
• Mixed Bed Polisher – Final ion exchange for ultrapure output.
• UV Sterilizer & 0.22 μm Filter – Ensures microbial control before use point.
• PLC + HMI Control Panel – Fully automatic operation with real-time monitoring.

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
