The semiconductor and electronics industries demand extremely high purity and stability in water quality, which directly impacts not only process yield but also component lifespan and quality control. The semiconductor industry is a typical "high-tech, high-water-consumption" industry. From wafer cleaning and etching to chemical processing, every process step requires high-purity water and strict wastewater discharge control. Accurate water quality monitoring ensures "process reliability," "chemical stability," and "discharge compliance," while appropriate "water resource reuse" can significantly reduce water costs and environmental pressure.
