Case Studies on Leachate Treatment
Leachate is wastewater generated from the moisture naturally present in landfill waste and from rainwater and snowmelt that percolates through the waste and underlying soil layers. It contains high concentrations of suspended solids as well as organic and inorganic compounds. In 2011, China’s leachate treatment market was valued at just RMB 1.176 billion; by 2021, this figure had grown to RMB 5.52 billion, reflecting a compound annual growth rate of 16.72% over the period. The market is expected to continue expanding at a robust pace in the years ahead.
Semiconductor Industry Application Cases
Semiconductors are the core components of electronic products and the cornerstone of the entire information industry. As semiconductor devices continue to shrink, with process nodes advancing from 28 nm to 7 nm, 5 nm, and beyond, advanced manufacturing processes have become increasingly sensitive to impurities. Consequently, the efficient removal of minute contaminants has grown more challenging, placing ever stricter demands on ultrapure water in terms of electrical conductivity, ion content, TOC, and other key parameters. This underscores the growing importance—and heightened complexity—of ultrapure water production technologies.
Food and Beverage Industry Application Cases
As global pollution intensifies and people increasingly prioritize health, the food and beverage industries are facing ever‑stricter regulatory requirements. Conventional municipal tap water or deep underground well water can no longer adequately meet consumer needs. National regulations for the food and beverage sector have evolved into a comprehensive system that governs every stage—from company establishment and production processes to final product inspection. Today, a Food Hygiene and Safety Licensing System (QS certification) is in place across numerous food categories and all beverage segments, mandating that both process water and finished‑product water must be purified, with electrical conductivity typically kept below 10 µS/cm.
Application Cases in the New Energy Industry
As the “dual carbon” strategy gains full momentum, the development of new‑energy vehicles and research into power batteries have attracted widespread attention, driving a corresponding surge in demand for battery materials. Among these, cathode materials—by far the largest category of raw materials in power batteries—have seen rapid growth in shipments, fueled by the expansion of the new‑energy vehicle market. Global demand for cathode materials is projected to reach 600,000 tonnes in 2021 and could exceed 2.15 million tonnes by 2025. Meanwhile, electric vehicles, as the largest downstream application segment for lithium batteries, account for more than 60% of total lithium‑battery consumption. This year, global lithium‑battery consumption for electric vehicles is expected to total 310 GWh, translating into an estimated demand for cathode materials of approximately 604,000 tonnes.
Photovoltaic Industry Application Cases
In recent years, as photovoltaic power generation has grown year after year, an increasing number of enterprises have adopted solar‑powered electricity. The entire photovoltaic industry is exhibiting a robust growth trajectory. At the heart of photovoltaic power generation are photovoltaic modules, whose production relies heavily on ultrapure water. In particular, the slicing and cleaning of silicon wafers require substantial quantities of ultrapure water, and the quality of this ultrapure water directly affects wafer quality, which in turn impacts the manufacturing of photovoltaic cells.
