The global water treatment chemicals market size was reached at USD 38.88 billion in 2024 and is expected to be worth around USD 58.16 billion by 2034, growing at a compound annual growth rate (CAGR) of 4.11% over the forecast period 2025 to 2034. The growing demand for clean drinking water and increasing water scarcity issues drive the market growth.
The water treatment chemicals market growth is driven by the increasing need for safe drinking water, aging water infrastructure, growing power generation, increasing awareness about water scarcity, and growing municipal investment in water treatment solutions.
Water treatment chemicals are substances added to water to improve the quality of water, purify water, and remove contaminants from water. The functionality of water treatment chemicals is to kill harmful bacteria, remove coagulation, adjust pH, inhibit pipe corrosion, and remove unwanted tastes. Water treatment chemicals prevent waterborne diseases, improve water quality, and reduce pollution.
The market is undergoing key technological innovations driven by the demand for sustainable operation and improving outcomes of treatment. One of the significant transformations is the integration of AI offers real-time data analysis and optimizes chemical dosages. AI analyses chemical concentration, pH, & turbidity and predicts future water quality issues. AI makes real-time adjustments and helps to maintain high-quality water standards. AI easily detects faults in equipment and optimizes the usage of chemicals. For instance, Xylem uses the AI-based Xylem Vue platform to optimize chemical use in water and wastewater utilities.
