China’s industrial water treatment chemicals market is highly diversified, reflecting its expansive industrial base and evolving environmental regulatory framework. The Ministry of Ecology and Environment (MEE) and various sector-specific discharge standards under the “GB” national standard system define effluent parameters that industrial facilities must meet. This has led to increased adoption of chemical treatments tailored to industry-specific water quality and reuse requirements.
In the power generation sector, particularly coal-fired plants, boiler feedwater treatment is governed by the DL/T 561 standard for thermal power water treatment, which specifies guidelines for oxygen scavenging and pH conditioning. Common oxygen scavengers used in Chinese power plants include carbohydrazide, recognized for its low toxicity and performance in high-pressure systems. Feedwater pH is often maintained using neutralizing amines such as ammonia or ethanolamine (ETA), in accordance with internal treatment practices to mitigate flow-accelerated corrosion (FAC), a known issue in heat recovery and condensate systems.
Cooling water treatment in thermal and industrial facilities is typically managed under DL/T 806, the Chinese standard for industrial circulating cooling water treatment. This includes the use of phosphonate-Zn formulations for corrosion control and dispersants to manage scaling in systems where high levels of dissolved silica (exceeding 200–250 ppm) are present. These formulations have been validated for use at elevated temperatures (>70°C) in power plant cooling circuits.
In the petrochemical and refining industry, demulsifier chemicals are essential for crude desalting. Chinese refiners commonly deploy nonionic polyol ester-based demulsifiers at dosage rates of 5–25 ppm to reduce basic sediment and water (BS&W) levels, consistent with the SH/T 0206 standard for crude oil quality. Achieving BS&W levels below 0.5% is typical to protect downstream heat exchangers and catalytic units.
Steel and metallurgical operations, particularly in provinces such as Hebei and Liaoning, are regulated under the GB 13456-2012 standard for effluent discharge from the iron and steel industry. Wastewater generated from cold-rolling and pickling processes is treated using acid demulsifiers followed by ultrafiltration membranes to reduce residual oil content below 10 mg/L necessary for compliance with discharge limits on petroleum hydrocarbons.
In electronics and semiconductor manufacturing, ultrapure water (UPW) generation is aligned with the SEMI F63 and China Electronic Grade Water Standards (SJ/T 31469). TOC levels are typically controlled below 0.5 ppb using 185 nm UV oxidation and membrane degasification. Selective ion exchange resins are employed for boron removal, a key requirement in semiconductor-grade water systems. Additionally, fluoride-laden wastewater from etching processes is treated using calcium chloride (CaCl₂) precipitation to form calcium fluoride (CaF₂), reducing fluoride concentrations to below 15 mg/L, in line with semiconductor industry wastewater treatment practices.
The textile and dyeing sectors in Zhejiang and Jiangsu provinces face significant wastewater challenges due to high color and COD content. Treatment practices follow the GB 4287-2012 discharge standard for textile finishing. Chemical oxidation processes such as Fenton's reagent and ozone systems are used for color removal, while electrodialysis (ED) and nanofiltration are increasingly deployed to concentrate and recover NaCl brine from dye bath effluents. Membrane scaling in these systems is prevented using antiscalants dosed typically in the 3–8 ppm range.
China’s broader environmental goals such as the “Dual Carbon” policy drive green chemistry initiatives across industrial water treatment. Under the Circular Economy Promotion Law and the NDRC’s Industrial Solid Waste Comprehensive Utilization Plan, manufacturers are increasingly incorporating coal fly ash-based materials into the production of inorganic flocculants, contributing to resource recycling targets. Simultaneously, biodegradable alternatives to phosphonates, such as polyaspartic acid (PASP) and polyepoxysuccinic acid (PESA), are promoted for corrosion and scale control applications to support long-term carbon reduction and eco-toxicity goals.
China's industrial water treatment chemicals market is undergoing a strategic shift as national environmental policies prioritize both carbon emissions reduction and water conservation. Central to this transformation is the “Dual Carbon” initiative, which aims to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. The 14th Five-Year Plan (2021–2025) includes strict mandates for industrial water reuse and pollutant discharge reduction, particularly targeting water-intensive sectors such as thermal power generation, iron & steel production, and electronics manufacturing.
According to China's Ministry of Ecology and Environment (MEE), new discharge standards under GB 37823-2024 will take effect in June 2025, setting a maximum phosphorus concentration of 0.5 mg/L in effluent from petrochemical facilities. This regulation has led to increased demand for phosphorus-free or low-phosphorus antiscalants and dispersants, particularly polyaspartic acid and polyepoxysuccinic acid (PESA), which offer enhanced biodegradability and lower environmental impact compared to traditional phosphate-based agents.
Industrial parks in provinces like Jiangsu and Zhejiang are implementing advanced water recycling infrastructure to meet high reuse targets. The Jiangsu Provincial Department of Ecology and Environment has mandated water reuse rates above 85% for textile industrial clusters, resulting in growing demand for high-performance antiscalants and sludge-reducing additives. These chemicals are used to improve the performance of reverse osmosis systems and thermal evaporators essential to Zero Liquid Discharge (ZLD) compliance.
Baowu Steel Group, one of China’s largest steelmakers, has publicly partnered with Bluetech Clean Energy to optimize chemical dosing using AI-driven systems. Their deployment of Bluetech’s WiseWater platform reportedly reduced chemical consumption and minimized sludge generation, contributing to operational efficiency and regulatory compliance in closed-loop water systems.
China’s semiconductor manufacturing expansion spurred by state policy support, strategic investment, and supply chain localization has created a growing market for ultra-pure water (UPW) treatment chemicals. The Ministry of Industry and Information Technology (MIIT) has included semiconductor fabrication in its strategic high-tech priorities under the “Made in China 2025” initiative, resulting in over ¥1 trillion in government-backed investments.
Leading domestic foundries such as Semiconductor Manufacturing International Corporation (SMIC), Yangtze Memory Technologies (YMTC), and ChangXin Memory Technologies (CXMT) are rapidly building fabs with UPW requirements ranging from 10,000 to 50,000 m³/day per site. According to SEMI (Semiconductor Equipment and Materials International), UPW used in advanced node manufacturing (≤5nm) must meet ultrapure standards such as <0.05 μg/L silica, <0.1 μg/L total organic carbon (TOC), and extremely low levels of metal ions.
To meet these specifications, suppliers are phasing out conventional reagents that risk trace metal contamination. Companies like Entegris and Pall have introduced ultra-high-purity filtration systems and chemical blends certified under SEMI C79 and SEMI F57 standards. Domestic suppliers including OriginWater and Beijing Tri-High are also developing metal-free formulations and PFAS-free coagulants to align with both environmental and technical purity requirements.
The market for ozone-based oxidants is also expanding due to their role in lithography and wafer cleaning. On-site ozone generation systems often based on Proton Exchange Membrane (PEM) technology require compatible high-purity chemicals, which must exceed 99.999% purity to prevent damage to silicon wafers.
With more than 150 fabs announced or under construction across China, industry analysts from China Semiconductor Industry Association (CSIA) estimate cumulative UPW-related chemical demand could reach ¥25 billion (~US$3.4 billion) by 2030. This includes not only treatment chemicals but also prequalified dosing agents, chelating resins, and filtration additives all of which are subject to strict SEMI material compatibility standards. The combination of regulatory backing and localized production incentives offers significant opportunities for global and Chinese water chemical suppliers alike.
