Electroplating & Coating

Electroplating processes require both high-quality pure water and reliable wastewater treatment to ensure product quality and environmental compliance.

Pure water is used in plating and rinsing to maintain surface finish and coating adhesion, while wastewater treatment is essential to remove heavy metals and enable safe discharge or reuse.

Our solutions help optimize water usage, reduce operating costs, and improve overall process stability.

1.Pure Water

Pure water with a conductivity of 5–15 μS/cm is typically used for plating bath preparation, while water with conductivity below 10 μS/cm is required for rinsing.

Membrane technologies such as ultrafiltration (UF) and reverse osmosis (RO) can also be used to recover valuable metal ions from rinse water. The treated water can be reused in the rinsing process, reducing water consumption and operating costs.

2.Wastewater

Treat electroplating wastewater and recover valuable resources.

• Removal of heavy metals (Ni, Cr, Cu, Zn)
• Support water reuse or compliant discharge
• Reduce environmental impact

Process:
Wastewater → Equalization → Chemical Treatment → Sedimentation → Filtration → Discharge / Reuse
