Water Purification Treatment for Precision Manufacturing

Water purification treatment equipment for precision manufacturing is a specialized system designed to purify raw water (e.g., tap water, groundwater) into high-purity or ultra-pure water to meet the exacting standards of precision manufacturing processes. In industries such as semiconductor production, electronics, aerospace, and optics, water is used for cleaning, rinsing, and cooling, requiring the removal of impurities, ions, particulates, and microorganisms to prevent defects, ensure product quality, and protect sensitive equipment.

Main Features

• Ultra-High Water Quality Assurance

Produces ultra-pure water (UPW) with extremely low levels of ions, organic compounds, particulates, and microorganisms, meeting standards like SEMI (Semiconductor Equipment and Materials International) or ASTM D512.

• Multi-Stage Purification Process

Pre-treatment: Sand filtration, activated carbon filtration, and softening to remove large particles, chlorine, and hardness.

Core Purification: Reverse osmosis (RO), electrodeionization (EDI), or mixed-bed ion exchange to achieve ultra-low conductivity (e.g., <0.055 μS/cm).

Disinfection: UV sterilization and ozonation to eliminate bacteria and organic matter.

Final Filtration: Sub-micron (0.05–0.1 micron) or nanofiltration to remove trace particulates.

• Automated Control

Features advanced PLC or touchscreen systems for real-time monitoring of water quality parameters (e.g., resistivity, TOC, particle count) and automated operation.

• Hygienic Design

Uses high-grade stainless steel (SUS316L) or specialized plastics for pipelines and tanks, with Clean-in-Place (CIP) systems to prevent contamination and maintain purity.

• Flexible Configuration

Customizable based on production scale, water quality requirements (e.g., 18.2 MΩ·cm resistivity for semiconductors), and raw water conditions.

Typical Applications

• Semiconductor Manufacturing: Ultra-pure water for wafer rinsing and cleaning to prevent contamination and ensure defect-free chips.

• Electronics Production: Water for cleaning printed circuit boards (PCBs) and components to avoid corrosion or residue.

• Optics Manufacturing: Purified water for lens polishing and coating processes to ensure clarity and precision.

• Aerospace Components: Water for surface treatment and cleaning of precision parts to meet strict tolerances.

• Cooling Systems: High-purity water for cooling sensitive equipment to prevent scaling or corrosion.
