With the acceleration of global energy structure transformation and the surging tide of intelligence,new energyThe strategic position of the semiconductor industry continues to rise, becoming the two core engines driving economic and social development. Behind the steady expansion of scale, the challenges of ultrapure water preparation and high difficulty wastewater treatment are constantly upgrading, which puts higher demands on the separation accuracy, stable energy efficiency, and full life cycle resource utilization ability of water purification processes. In this context, membrane separation technology, with its multiple advantages such as high efficiency, energy saving, green and low-carbon, connects key links such as production and water cycle, and builds a solid technological foundation for the high-quality development of new energy and pan semiconductor industries.
Hangzhou Haina Environmental Protection Technology Co., LtdHaina Environmental Protection (referred to as "Haina Environmental Protection") precisely anchors the strict water quality requirements of the new energy and pan semiconductor industries, gathers cutting-edge scientific research forces from universities and research institutes, and focuses on polishing a multi-level precision filtration product matrix, covering key material cleaning, chemical liquid filtration, wet metallurgy and other scenarios comprehensively. Breaking through the monopoly pattern with Chinese "chips", Haina Environmental Protection is relying on the hard core "membrane" power to continuously deliver independently controllable and comprehensive cost-effective full chain water treatment solutions to the market, fully demonstrating the responsibility of national high-tech enterprises and helping to achieve a win-win situation of green and low-carbon transformation and cost reduction and efficiency improvement.
Extreme Purification
Guarding the "lifeline" of precision manufacturing with lower energy consumption
In the manufacturing process of new energy and pan semiconductor industries, whether it is electrolyte preparation, electrode cleaning, orchipHigh standard ultrapure water is required for key processes such as cleaning, etching, and polishing. Any tiny impurities, particles, dissolved gases, bacteria, etc. in water may cause product defects, resulting in performance damage, decreased yield, and irreversible production losses. For example, residual metal ions may disrupt the threshold voltage of transistors, dissolved gases may interfere with the uniform growth of oxide films on the surface of silicon wafers, and organic matter may cause short circuits or leakage.
In response to the above, Haina Environmental Protection has been able to effectively assist customers in achieving efficient and stable production of ultrapure water through the collaborative efforts of multiple types of membrane products.
among which,Extremely strong anti pollution film XFR seriesAs a core component, it forms the "first core barrier" for high-purity water quality through patented membrane making technology and molecular level structural design. This product has a stable desalination rate of over 99.6%, with a minimum desalination rate of over 99.3%. It has outstanding anti pollution ability and can effectively inhibit the adhesion of pollutants. The energy consumption of a single system is only 0.23kw · h/m ³, which is better than imported products of the same level. It has excellent performance and higher cost-effectiveness.

For dissolved oxygen, carbon dioxide, etc. in water, HainaNew generation high-performance degassing membraneWithout any pH adjustment, ammonia nitrogen in water can be removed to 1 ppm, dissolved oxygen can be reduced to 1 ppb, and carbon dioxide can be removed to 1 ppm. After reasonable arrangement, higher quality ultrapure water can be produced without additional pollution. Compared to similar products on the market, Haina Environmental Protection's degassing membrane product adopts patented structures such as weaving, central tube water distribution, and baffles. The external quality coefficient of the membrane wire is more than three times that of the bundled membrane wire packaging method, and the amount of membrane used can be reduced by more than 50%. This not only ensures stable water quality standards, but also effectively reduces enterprise investment costs.

Circular recycling
Integrated membrane technology for zero discharge of Bright Sword wastewater
With accelerating the comprehensive green transformation of economic and social development as the core strategic task, the top-level design of the 15th Five Year Plan has been intensively formulated. Through measures such as target guidance, standard guidance, and technical support, a clear path has been pointed out for zero discharge of industrial wastewater. In the future, water treatment not only needs to achieve environmental standards, but also needs to break away from traditional end of pipe treatment thinking and truly achieve multiple values of water conservation, pollution reduction, carbon reduction, and quality and efficiency improvement. The new energy and pan semiconductor industries are also at a critical juncture of transitioning from "standard emissions" to "value growth" paradigm.
Wastewater treatment also relies on the support of precision filtration technology. To adapt to the precision manufacturing conditions of new energy and general semiconductors, Haina Environmental Protection has formed a systematic and diversified approachMicroelectronics filtration solutionStarting from the pre-treatment stage, Haina can provide high flow filter cartridges, perfluorinated filter cartridges, capsule filter cartridges, and matching filters, etc., which purify the wastewater layer by layer, efficiently intercept pollutants and salts in the wastewater, and achieve deep treatment and resource utilization of wastewater. The produced water can be recycled for the front-end process, and the concentrated high salt wastewater is further treated to achieve zero discharge requirements, fundamentally solving the problem of wastewater discharge and helping enterprises achieve their "pollution reduction and carbon reduction" goals.

according toFiltering requirements for special materials such as binders, electrolytes, electrode slurries, etc. in the new energy industryHaina Environmental Protection has developed a targeted solution: filtering the binder separately before mixing the slurry can suppress the probability of producing coarse aggregates during slurry mixing, and extend the service life of the filter element after mixing and before coating; By optimizing the filter cartridge configuration, various undissolved substances and impurities such as metals in the electrolyte can be removed, reducing overall production costs; In the process of positive and negative electrode slurry production, using Bayer filtration product BH series to filter the slurry can make the slurry distribution more uniform, effectively remove non-magnetic substances, and reduce the coating process defect rate.
In addition, Haina Environmental Protection focuses on the pain points of strong acid, high solid content, and high pollution in the lithium battery industry wastewaterAcid resistant lithium battery industrynanofiltration membraneBecoming a powerful tool for acid circulation and efficient recovery of metal resources. The retention rate of 2000mg/L magnesium sulfate is>99%, and the conditions of 20% sulfuric acid, 10% hydrochloric acid, 30% phosphoric acid, and 4% nitric acid can operate stably for a long time. The retention rate of divalent and multivalent metal ions is>95%. A series of measured data shows that the strength of this product is at the forefront of the industry. It has overcome the limitations of traditional nanofiltration membranes, such as easy hydrolysis, structural damage, and rapid performance degradation under strong acid conditions, and has now become the first choice for many lithium wet metallurgy enterprises.
