China Cooling Water Treatment Market to Reach USD 4.1 Billion by 2032, Growing at a CAGR of 6.45% During 2026–2032

The China cooling water treatment market was valued at USD 2.6 billion in 2025 and is projected to grow from USD 2.8 billion in 2026 to USD 4.1 billion by 2032. Driven by the expansion of thermal power generation, accelerating industrial water reuse, and increasingly stringent environmental policies, the market registers a compound annual growth rate (CAGR) of 6.45% during the 2026–2032 forecast period.

In parallel, water treatment chemicals represent the leading offering category across the marketplace ecosystem. The segment's market leadership is sustained by its recurring operational expenditure model, as chemical consumables are required continuously throughout the entire operating life of cooling systems. As a result, massive industrial facilities and advanced computing projects depend heavily on specialized formulations to prevent scaling, corrosion, and biofouling.

Furthermore, the power generation sector constitutes the dominant end-use industry across the country. This prominent position is heavily reinforced by China maintaining the world's largest operational fleet of thermal and recirculating cooling systems. Additionally, state-level energy conservation plans require substantial efficiency upgrades for generating units, prompting plant operators to adopt high-performance corrosion inhibitors, scale control chemistries, and automated monitoring equipment.

Regionally, East China and other core industrial hubs continue to drive national momentum, underpinned by hyperscale data center expansions and dense petrochemical complexes. Accelerated artificial intelligence computing deployment and stringent national water-use caps are pushing industrial operators toward closed-loop and high-recovery water management platforms, states the comprehensive research report, “China Cooling Water Treatment Market Analysis, 2026–2032”.
