The global water treatment chemicals market size was valued at USD 35.36 billion in 2023 and is projected to grow from USD 37.45 billion in 2024 to USD 61.05 billion by 2032, exhibiting a CAGR of 6.3% during the forecast period. North America dominated the water treatment chemicals market with a market share of 39.51% in 2023.

Chemicals are used in the process of water treatment in order to make water more acceptable for end-use such as drinking, cooking, irrigation, and other industrial processes. Some of the chemicals are sodium metabisulfite, ferric chloride, and Sodium Hexametaphosphate (SHMP). The chemical industry uses various water treatment methods involving both physical and chemical methods to remove substances such as sand, minerals, bacteria & viruses, and others. Water, being an essential resource for households and has numerous uses in end-use industries, has created a high demand for water treatment in order to reuse and recycle. The increasing need for water consumption due to the growing population and industrial use is expected to drive the market globally.

The demand for water treatment chemicals, equipment, and services across all regions was significantly impacted during the COVID-19 pandemic due to supply chain disruption, shortage of chemicals & inventory, short-term production halt, economic slowdown, trade restrictions, changing consumer behavior, and other reasons. Due to supply chain disruption across key consuming countries across all regions, in 2020, the year-on-year growth rate of the global market considerably dropped as compared to 2019. However, on account of mitigation strategies and business continuity plans adopted by leading manufacturers and suppliers, backed by respective government initiatives to recover the economy, the market is projected to recover slowly in the upcoming years.

Water Treatment Chemicals Market Trends

Urbanization and Population Growth in Emerging Economies Provides Beneficial Market Opportunities

Urbanization and population growth result in increased municipal water requirements. Municipalities need to treat water to ensure its safety for consumption, and water treatment chemicals are integral to this process. Moreover, growing urban areas contribute to higher levels of industrial and domestic wastewater, necessitating advanced water treatment solutions. Urbanization is often accompanied by a surge in population and a subsequent rise in water consumption for various purposes such as domestic use, commercial activities, and public services. As cities expand, there is a greater need to ensure sustainability and safety for the growing urban population.

Moreover, municipalities are tasked with providing clean and safe drinking water to residents. This influx of people into urban areas amplifies the challenges associated with sourcing, treating, and distributing water. Water treatment chemicals are vital components of municipal water treatment processes, helping to eliminate contaminants and pathogens from the water supply. Thus, urbanization and population growth create a heightened demand for water treatment chemicals as municipalities strive to ensure a secure and clean water supply for their residents, manage wastewater effectively, and address the environmental and public health implications of urban expansion.

Water Treatment Chemicals Market Growth Factors

Growing Demand for Chemically Treated Water in Various End-use Industries Will Aid Market Growth

As industries expand, there is a parallel increase in water consumption. Sectors such as manufacturing, power generation, and chemical processing require substantial amounts of water for their operations. Effective water treatment chemicals become essential to maintain water quality, reduce pollutants, and meet environmental standards. In addition, growing awareness of water scarcity issues prompts industries to adopt sustainable water management practices. Water treatment chemicals enable the recycling and reuse of water, reducing overall water consumption and minimizing environmental impact. Moreover, in developing economies such as China, India, Japan, Mexico, and Brazil, increased industrialization and urbanization have led to a surge in the demand for water chemicals. These countries are investing in water infrastructure and treatment solutions to address water quality challenges associated with rapid economic growth.


Presence of Alternative Water Treatment Technology Aid to Hamper Market Growth 

The growing number of processes of water treatment and the presence of alternative treatment technologies will hamper the growth of the market. At the same time, the need for sustainable formulations and susceptibility to copying patents will challenge its growth. Alternative water treatment technologies encompass innovative and eco-friendly approaches to water purification, such as advanced filtration systems, membrane technologies, and emerging non-chemical treatment methods.

These alternatives often attract industries and municipalities seeking sustainable and cost-effective solutions, steering away from traditional chemical-based water treatment. Membrane filtration, for instance, offers a chemical-free process that reduces environmental impact. Additionally, ultraviolet (UV) and electrochemical methods are gaining traction for their efficacy in disinfection without relying on chemical additives.

Water Treatment Chemicals Market Segmentation Analysis

By Type Analysis

Coagulants & Flocculants Segment Accounted for the Largest Share Due to its Treatment Techniques

Based on type, the market is segmented into pH conditioners, coagulants & flocculants, disinfectants & biocidal products, scale & corrosion inhibitors, antifoam chemicals, and other chemicals.

The coagulants & flocculants segment held the largest water treatment chemicals market share in 2023 as they are vital chemicals required for causing sedimentation in sludge treatment techniques. These chemicals aid the removal of impurities by causing particles to clump together, facilitating easier filtration and purification of water. This is particularly vital in wastewater treatment and ensuring the supply of clean water for various applications.

Disinfectants & biocidal products held a significant market share during the forecast period due to the increasing awareness of waterborne diseases and the need for safe and clean water sources driving the demand for effective disinfectants & biocidal solutions. Additionally, stringent regulations and standards for water quality in various industries and public water supplies further drive the water treatment chemicals market growth.

Municipal Segment Accounted for the Largest Share Due to its High Demand

Based on application, the market is segmented into municipal and industrial.

The municipal segment dominated the market share in 2023, propelled by agriculture, which constitutes over 30% of global water demand. Additionally, increased wastewater production from residential buildings, including water usage in adventure parks and swimming pools, is expected to drive demand for advanced treatment solutions. For example, the Central Public Health & Environment Engineering Organization (CPHEEO) report indicates that approximately 70-80% of water supplied to domestic applications is converted to wastewater after use.

The industrial segment is expected to experience considerable growth during the forecast period. This is owing to the imposition of more stringent regulations expected to be enforced in developing countries. Advancements in technologies such as ozone treatment and bioremediation developed by Culligan Industrial Water and Suez Worldwide, amongst others, will be critical factors for the segment’s growth.


Based on geography, the market is categorized into Europe, North America, Asia Pacific, Latin America, and the Middle East & Africa.
