Summary of Key Points
The industrial water treatment industry has completed its “first half” (driven by mandatory policy standards, industrial capacity expansion, and zero-emission requirements for coal chemical plants in the western regions) and is now entering a new phase. The focus of demand has shifted from simply meeting compliance standards to more sophisticated approaches that involve resource utilization, high-end applications, and emerging industry needs. Opportunities in this new phase come from four main areas: transforming water into a recyclable resource, integrated management of industrial parks, producing high-quality process water (such as ultra-pure water for semiconductors), and addressing new types of pollutants. Additionally, emerging technologies like AI, data centers, green hydrogen production, and seawater desalination are creating significant growth opportunities. To seize these opportunities, companies must shift from providing mere engineering solutions to offering comprehensive, technology-driven approaches that address specific industry needs.
The First Half: Growth Driven by Policy and Factory Construction
The first half of the industry (2008-2020) was characterized by strong demand, fueled by three main factors:
1. Mandatory pollution control policies: The government introduced regulations like the “Water Ten Measures” and environmental taxes, forcing polluting industries (such as chemicals, textiles, and electroplating) to invest in wastewater treatment facilities or face penalties.
2. Expanding industrial capacity: Industries like steel and chemicals grew rapidly, leading to a continuous stream of new orders for water treatment systems.
3. Zero-emission requirements for coal chemical plants in the west: Water-scarce regions like Inner Mongolia and Xinjiang required all wastewater to be recycled, creating a niche market for high-salinity wastewater treatment.
However, by 2023, these factors had weakened:
- Most of the necessary facilities had been built, with reuse rates reaching 93%, making further upgrades less profitable than building new systems.
- Traditional heavy industries were no longer expanding, reducing new orders for water treatment.
- Coal chemical projects in the west continued but were less likely to drive overall industry growth due to their long cycles and concentrated market players.
Therefore, the simple business model of the first half is no longer sustainable, and companies need to adapt to the new challenges of the second half.
The Second Half: Water as a Profitable Resource
The most significant change in the second half is that water is no longer just a waste to be treated but a valuable resource to be sold. Both policy and market forces are driving this shift:
- Policy guidance: Regulations such as the “Industrial Wastewater Recycling Implementation Plan” encourage the reuse of wastewater, and the “Water Use Rights Trading Rules” allow for the trading of water resources.
- Economic benefits: Treating wastewater can now generate revenue; for example, high-salinity wastewater can be processed to extract industrial salts, and waste brine from salt lakes can be used to extract lithium and rare earth elements, turning treatment plants into resource recovery facilities. Some wastewater treatment projects now have return rates exceeding 15%.
The treatment approach has also evolved, with a shift from treating individual factories to managing entire industrial parks efficiently (e.g., the Hengshui High-Tech Zone treats wastewater for 19 chemical companies together).
Emerging Industries Creating New Demand
New growth in the industry comes from emerging sectors that require specialized water solutions:
1. Cooling water for AI data centers: As AI processing power increases, so does water consumption (e.g., a 1-megawatt data center uses 15,000-30,000 cubic meters of water per year). Companies providing cooling solutions for data centers are in high demand due to environmental regulations.
2. Ultra-pure water for green hydrogen production: Green hydrogen production requires extremely pure water (similar to that used in semiconductors), with each kilogram of hydrogen requiring 9-10 liters of ultra-pure water. The growth of green hydrogen projects (e.g., Sinopec’s 20,000-ton project in Xinjiang) has driven demand for corresponding ultra-pure water.
3. Seawater desalination and integrated park management: Coastal industrial parks rely on seawater desalination to meet their water needs, reducing costs and addressing water scarcity issues.
4. Domestic substitution of ultra-pure water for semiconductors: The semiconductor industry, which previously relied on imported ultra-pure water, is now seeing domestic competition. Orders for ultra-pure water equipment for single GW (gigawatt) production facilities can amount to hundreds of millions of yuan, with high margins.
Seizing Opportunities through Technology and Focus on Specific Industries
In the second half of the industry, success will depend on companies that:
- Master advanced technologies: Specialized treatments for new pollutants (e.g., PFAS and antibiotics) are needed to secure orders from pharmaceutical and fine chemical industries.
- Understand industry-specific needs: Integrated park management requires knowledge of complex pipeline networks and recycled water systems. For data centers, understanding the water requirements of computing equipment is essential.
- Leverage AI for efficiency: AI can help optimize chemical dosing and energy consumption, reducing costs and increasing competitiveness.
In summary, the focus in the second half of the industrial water treatment industry will be on providing comprehensive solutions that combine resource management, data analysis, and carbon rights management. Only by adapting to changing demands and deeply integrating technology with specific industry needs can companies thrive in these new markets.
