Impure water sources are responsible for numerous illnesses such as cholera, dysentery, and typhoid, resulting in increased death rates, especially in developing areas. This heightened awareness of health, along with more rigorous regulations on water quality, is driving the implementation of modern water treatment technologies to safeguard public health and curb the transmission of waterborne diseases. For instance, according to CDC 2024, the estimation says that 1.1 Million people in the U.S. get sick every year from germs in drinking water. Legionella germs are the most common cause of illness related to drinking water.
UV and ozone treatment purify and disinfect the solution with minimal chemical usage. In the process of UV treatment, harmful microorganisms are deactivated by light, while ozone treatment employs ozone gas to decompose pollutants and pathogens into less harmful components. These techniques are regarded as environmentally friendly and sustainable since they do not generate chemical byproducts. As Manufacturers and Governments adopt these methods, the reliance on chemical treatments like chlorine or flocculants diminishes, thereby restricting the market for chemical-based solutions.
New facilities emerging in Africa and Latin America are presenting a considerable opportunity for the market of chemicals used in water and wastewater treatment. As these regions undergo rapid industrialization and urban development, there is an escalating demand for advanced water treatment systems to accommodate the increasing populations and industries. The need for chemicals like coagulants, flocculants, disinfectants, and membrane treatment solutions is projected to grow as new plants, manufacturing sites, and municipalities invest in sustainable water management practices to tackle health and environmental issues. For instance, in January 2024, Veolia launched its new water treatment plant in São Paulo, Brazil. It emphasized improving purification processes by using advanced chemical treatments. This is part of Veolia's larger strategy to enhance water sustainability across Latin America.
Coagulants and Flocculants hold the largest market share by revenue in Water and Wastewater treatment industry. These chemicals are used in large amounts due to their wide functions such as removing heavy metals, and organic contaminants and reducing the water turbidity. Traditionally, various inorganic metal-based chemicals like aluminum sulfate, ferric chloride, and ferric sulfate are used globally as coagulants in water treatment applications. However, these chemicals have a high cost, toxic nature, and corrosive properties. The development of new, effective and bio-based coagulants and flocculants have shown the sustainable pathway for coagulants and flocculants in Water Treatment industry. For instance, Bio-based coagulants, derived from natural ingredients are gaining traction in the market, presenting sustainable and environmentally friendly solutions. These chemicals also align with stringent regulations, such as the EU Water Framework Directive.
With the growing need for safe and clean drinking water, and stringent regulations over industrial waste water disposal, the demand for Coagulants & Flocculants will bolster during the forecast period. According to the Persistence Market Research Analysis, the market for Bio-based sustainable coagulants and flocculants will grow with 8.7% CAGR during 2025 and 2032.
It is expected that the municipal water and wastewater treatment segment will lead the global market, representing 27.4% of the total share. Driven by rapid urbanization, population growth, and rising concerns about waterborne diseases. Rising municipal water and wastewater treatment sector is increasing due to rising global water consumption and the need for safe and potable water. Rapid urbanization and population growth create immense pressure on municipal authorities to provide clean drinking water and manage wastewater effectively. Certain corporations also provide wastewater treatment chemicals to municipal authorities to manage the wastewater treatment. For example, Aditya Birla Chemicals has been at the forefront of providing advanced coagulants like polyaluminium chloride (PAC) and aluminum chlorohydrate (ACH) for municipal water treatment plants. These chemicals are instrumental in removing impurities, thereby ensuring safer drinking water for communities.
Asia Pacific accounted for 38.0% worldwide market share in 2025, dominating the global industry. This is due to the high standards established for water quality and wastewater discharge by addressing new government initiatives, and subsidies. For instance,
India's sewage treatment regulations are governed by central laws such as the Water (Prevention and Control of Pollution) Act of 1974 and the Environment Protection Act of 1986. These laws are enforced by the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs). They establish discharge standards to ensure that industries and municipalities treat wastewater effectively, thereby reducing pollution. Additionally, the National Green Tribunal (NGT) frequently issues directives aimed at improving compliance across the country.
The demand for water & wastewater treatment chemicals in North America is rising in 2025. The region is poised to account for 26.8% market share in 2024. The chemical & petrochemical industries are sources of industrial wastewater that need a relevant treatment before releasing into the environment. The need for chemicals used in water and wastewater treatment has increased as a result. For example, The Clean Water Act (CWA), 1972 governs the release of pollutants, such as wastewater, into water bodies within the United States. It requires the implementation of appropriate water and wastewater treatment procedures to comply with effluent standards and water quality regulations. The process needs huge amounts of chemicals to overcome the need to complete the required procedures.
Europe's Government has set high standards for water quality and wastewater discharge. This is due to following high standards for water quality and wastewater discharge. For instance, Urban Waste Water Treatment Directive (UWWTD) and Drinking Water Directive (DWD) are the regulations which has set high standards for wastewater treatment in Europe to ensure quality, and safety. The growth is supported by increasing emphasis on specific regulatory standards, which will likely continue the demand upward trend and drive market expansion over the next few years.
The global water & wastewater treatment chemicals market players are implementing strategies to maintain and enhance their positions in the competitive landscape. With innovation being a crucial factor, several companies are continuously developing a wide range of eco-friendly, and sustainable chemical solutions. These companies prioritize broadening their product lines and geographical presence by engaging in mergers, acquisitions, and collaborations. The industry is also witnessing the rise of innovative entrants offering environmentally friendly and sustainable treatment chemicals. Fierce competition and regulatory demands compel ongoing product innovation and technological progress.
