PCB Industrial Wastewater Treatment System | WTEYA
The PCB (Printed Circuit Board) manufacturing industry generates complex wastewater containing heavy metals, organic pollutants, and high COD levels. Effective treatment is essential for environmental compliance and sustainable operations.
Understanding PCB Wastewater Challenges
PCB manufacturing involves multiple processes including etching, plating, and cleaning, each producing distinct wastewater streams. These effluents typically contain:
- Heavy metals (copper, nickel, tin, lead)
- High concentration of organic compounds
- Elevated COD and BOD levels
- Acidic or alkaline pH values
- Complexing agents and surfactants
Traditional treatment methods often struggle with complete removal of these contaminants, especially chelated heavy metals that resist conventional precipitation.
WTEYA's Comprehensive Treatment Solution
WTEYA provides integrated wastewater treatment systems specifically designed for PCB manufacturers. Our solution combines advanced physical-chemical processes with membrane technology and evaporation systems.
Core Treatment Process
1. Pre-treatment Stage - Equalization tank for flow and quality balancing - pH adjustment to optimal range - Oil and grease separation
2. Heavy Metals Removal - Advanced chemical precipitation with specialized reagents - Coagulation and flocculation - Dissolved air flotation (DAF) for solids removal
3. Advanced Oxidation - Breakdown of complex organic compounds - Destruction of chelating agents - COD reduction before biological treatment
4. Membrane Concentration - Ultrafiltration (UF) for suspended solids removal - Reverse osmosis (RO) for dissolved salts concentration - Nanofiltration for selective contaminant removal
5. MVR Evaporation & Crystallization - Mechanical vapor recompression technology - Energy-efficient concentration of high-salinity wastewater - Crystal production for resource recovery
Key Advantages of WTEYA Systems
High Removal Efficiency: Our systems achieve >99% heavy metals removal and >95% COD reduction, ensuring discharge compliance with the strictest environmental standards.
Zero Liquid Discharge Option: Complete wastewater recycling with ZLD configuration, eliminating liquid discharge and maximizing water reuse.
Energy Optimization: MVR evaporators reduce energy consumption by 30-50% compared to conventional evaporation, significantly lowering operating costs.
Automated Operation: PLC-controlled systems with remote monitoring capabilities minimize manual intervention and ensure consistent performance.
Compact Design: Modular, skid-mounted units reduce footprint and simplify installation in existing facilities.
