Latest Developments and Application Trends of Polyacrylamide (PAM) in Water Treatment (2023-2024)

I. Industry Overview and Technological Advances

Polyacrylamide (PAM), as one of the most important water treatment chemicals, has made significant progress in technological innovation and market applications in recent years. According to the latest market research report, the global PAM market reached $4.58 billion in 2023 and is projected to grow to $6.23 billion by 2028, with a compound annual growth rate of 6.3%. The water treatment sector accounts for over 65% of total consumption, serving as the core driver of industry growth.

1. Breakthroughs in Anionic Polyacrylamide (APAM)

In 2023, a research team from the University of Science and Technology of China published significant findings in *Nature Water*, successfully developing a novel APAM material with “smart response” characteristics. Utilizing molecular imprinting technology, this product can automatically adjust its molecular configuration based on pollutant types in water, improving heavy metal ion removal efficiency by 40%, especially suitable for mining wastewater treatment. Field data from a copper mine wastewater treatment project in Jiangxi showed this material achieved 99.2% copper ion removal while reducing treatment costs by 35%.

Concurrently, Japan’s Mitsubishi Chemical introduced a high-temperature-resistant APAM series that maintains stable performance at 80-120°C, addressing technical challenges in oil and gas field wastewater treatment. This product demonstrated exceptional performance in Saudi Aramco’s oilfield water treatment system, accelerating floc formation speed by 50% and reducing settling time to two-thirds of conventional products.

2. Technological Upgrades in Cationic Polyacrylamide (CPAM)

The sludge treatment sector has witnessed transformative changes. In early 2024, Germany’s BASF launched a new-generation ultra-high molecular weight CPAM product with a molecular weight exceeding 20 million Daltons. Through specialized cross-linking technology, this product forms denser network structures during sludge dewatering, achieving post-dewatering sludge moisture content below 58%—a 10-percentage-point improvement over conventional products. After adopting this technology, Paris Municipal Wastewater Treatment Plant increased sludge treatment capacity by 30% while reducing chemical consumption by 15%.

More notably, a Dutch startup developed a biosynthetic CPAM using CRISPR gene-editing technology. Produced via engineered *E. coli* fermentation, this process entirely avoids acrylamide monomer use, reducing product ecotoxicity by 90% and cutting carbon emissions by 65% during production. Although current costs remain ~20% higher than chemical synthesis methods, significant competitive advantages are expected upon achieving scale production by 2026.

3. Expanded Applications of Nonionic Polyacrylamide (NPAM)

NPAM demonstrates unique advantages in specialized water treatment. In late 2023, Dow Chemical introduced a pH-sensitive NPAM series that automatically adjusts molecular chain extension within pH 2-12, improving nano-scale suspended solids capture efficiency by 3-5 times. This technology has been successfully applied in ultrapure water preparation for the semiconductor industry, achieving water quality standards of 18.2 MΩ·cm.

South Korean researchers developed visible-light-degradable NPAM by introducing azobenzene structural units. Residual polymers can degrade into small-molecule compounds within 48 hours under natural light, completely resolving traditional PAM residue issues. This technology has been piloted in select Seoul drinking water plants, with commercialization expected by 2025.

II. Market Dynamics and Regional Developments

1. Shifts in Global Market Landscape

The Asia-Pacific region has become the fastest-growing PAM market, accounting for 46% of global consumption in 2023, with China contributing the majority of growth. Data from China Petroleum and Chemical Industry Federation shows China’s PAM production reached 920,000 tons in 2023, with imports maintaining a 15% annual growth rate—particularly for high-end CPAM products, where import dependence remains as high as 40%.

The European market shows differentiated trends. Driven by stringent environmental regulations, biodegradable PAM products increased market share from 8% in 2020 to 22% in 2023. France’s Veolia announced plans to fully replace traditional CPAM with green alternatives by 2026.

The North American market, driven by shale gas development, continues strong APAM demand. U.S. PAM imports grew 18% in 2023, with 60% used for oil and gas extraction wastewater treatment. Notably, Mexico has emerged as a new production hub, with multiple multinationals establishing local production bases.

2. Pricing and Supply Chain Dynamics

From 2023 to 2024, PAM raw material markets experienced significant fluctuations. Acrylamide monomer prices hit historic highs in Q3 2023 but returned to reasonable levels by Q2 2024 as China added new production capacity. However, cationic reagent DMC (methacryloyloxyethyl trimethyl ammonium chloride) prices continued rising due to tight upstream propylene oxide supply, increasing CPAM production costs by 12-15%.

Regarding supply chains, industry leaders accelerated vertical integration. Solvay Group invested €300 million in a new integrated production base in Belgium, enabling full-process production from acrylonitrile to final products. Expected to launch in 2025, this will reduce comprehensive costs by 20%. Small and medium enterprises shifted toward specialization—for example, Italy’s Italmatch focused on developing specialized APAM formulations for seawater desalination.
