Semiconductors & Microelectronics
Molewater uses technology to provide worry-free water quality services for the innovation and sustainable development of emerging industries.
The manufacturing of semiconductor chips requires ultra-pure water with a stable resistivity of 18.2 MΩ·cm, and the tolerance for impurities such as TOC, particles, and metal ions is at the ppt level. Meanwhile, there are significant differences in water quality indicators among different process links (such as wafer cleaning and etching) and different products (such as 12-inch wafers and third-generation semiconductors), so the system must have dynamic adaptability
The electricity and water consumption for ultra – pure water preparation accounts for more than 20% of the total energy consumption of semiconductor factories. The water recovery rate of traditional systems is only 50% – 60%. Under the current “dual carbon” policy, enterprises are facing enormous pressure to save energy, reduce consumption, and control environmental protection costs.
Transforming Microelectronics Wastewater into Resources
Molewater Treatment provides cutting-edge ultrapure water technology and customized system services, deeply serving core fields such as semiconductors, microelectronics, photovoltaics, and new energy, and driving industrial technological upgrading and sustainable development with the power of purity.
Relevant Technologies
The system adopts a combined filtration process of multi-media filtration, activated carbon adsorption, softening, and precision filtration, which effectively protects the service life of the subsequent RO membrane and EDI module.
As the core purification process of the system, it can effectively remove more than 99% of dissolved salts, heavy metals, microorganisms, and endotoxins in water through membrane separation technology.
This technology combines electrodialysis and ion exchange, does not require acid-base regeneration, and is a core green process for preparing “high-purity water”.
Ultra-pure uniform particle resin can deeply remove trace ions and ensure that the terminal resistivity meets the standard.
Ultraviolet sterilization and 0.22 μm terminal sterilization filtration are used to control the risks of organic matter and microorganisms, and intercept micro-particles, colloids, and bacterial fragments to meet the water standard for ultra-pure water.
