Electroplating Pure Water System

Typical tap water contains calcium, magnesium, chlorides, and other dissolved solids that interfere with plating chemistry. Our electroplating pure water system removes these contaminants, producing high-purity deionized (DI) water meeting the stringent requirements of modern metal finishing.

The DI water equipment for electroplating delivers water with conductivity as low as 0.1-10 μS/cm — suitable for:

Plating bath makeup (conductivity <15 μS/cm)

Final rinse stages (conductivity <10 μS/cm)

Sealing and passivation solutions

This industrial water purification system uses advanced reverse osmosis (RO) and electrodeionization (EDI) technology to produce consistent-quality pure water without the chemical regeneration required by traditional ion exchange systems.

Water Quality Requirements for Electroplating

Using water with conductivity above these limits risks:

Calcium/ magnesium scaling on plated surfaces

Chloride-induced pitting on stainless steel and nickel deposits

Organic contamination leading to dull or hazy finishes

Key Specifications

The electroplating water treatment system is available as a skid-mounted modular unit for easy installation, or fully integrated into a closed-loop water recycling plant with wastewater treatment.

Technical Process Flow

Our DI water system follows a multi-stage purification process:

The RO membrane is the heart of the electroplating pure water machine, rejecting 99%+ of dissolved salts. For higher purity requirements, EDI replaces traditional mixed-bed ion exchange — eliminating hazardous chemical regeneration and reducing operating costs.

Key Advantages

✅ Consistent Water Quality – RO + EDI technology produces stable purity without the "tailing" (purity drop) of traditional ion exchange systems.

✅ No Chemical Regeneration – Unlike mixed-bed ion exchange, EDI uses electricity to continuously regenerate resin — eliminating hazardous acid and caustic handling.

✅ Reduced Operating Costs – Lower labor costs and no chemical purchase compared to traditional DI systems.

✅ Compact Footprint – Skid-mounted design saves floor space in crowded plating shops.

✅ Fully Automated – PLC-controlled with conductivity monitoring and automatic flush cycles.

✅ Low Maintenance – RO membranes typically last 3-5 years; EDI modules 5-10 years.

✅ Increased Bath Life – Pure water prevents contamination buildup in plating baths, extending solution life.

✅ Improved Rinse Effectiveness – DI water rinses more effectively than tap water, reducing water spots and stains.

✅ 12 Months Warranty – Full after-sales support.

FAQ

What water quality is required for electroplating?

Most plating bath makeup water should be below 15 μS/cm conductivity.

Is RO water sufficient for electroplating?

For standard plating, RO water is usually sufficient. For precision plating and electronics plating, RO+EDI is recommended.

What is the difference between RO and EDI?

RO removes dissolved solids, while EDI further removes ions to produce ultra-pure water without chemical regeneration.

Can the system be integrated with wastewater recycling?

Yes. JUNDA can provide complete water treatment and recycling solutions.

What industries use electroplating pure water systems?

Automotive, electronics, PCB, fasteners, anodizing, and decorative plating industries.
