The plant also uses advanced energy-efficient and water recycling technologies, indicating the Chinese investment in efficient wastewater treatment. The increasing demand for inorganic coagulants such as PAC is highlighted by this growth, which is critical in controlling the pollution caused by rapid urbanization and industrialization.

Additionally, the robust infrastructure of wastewater treatment in China, with 2,471 urban facilities at an annual treatment capacity of 52,585 million m³, which is treated at a rate of 96.81%, indicates the growing demand of treatment agents, such as inorganic coagulants, due to the surge in pollution control efforts and improvement of water quality, and the need to support the demand of water treatment chemicals, including inorganic coagulants. These chemicals are essential in the removal of suspended solids and pollutants to comply with the more demanding environmental standards and the promotion of better water quality.

India’s inorganic coagulants market is projected to grow with the fastest CAGR over the projected years from 2026 to 2035, owing to the high urbanization, industrialization, and growing water contamination, which demand effective wastewater purification. According to the Central Pollution Control Board (CPCB), India generates 33212 million liters per day of sewage, and the current sewage treatment (STP) capacity is 6190 MLD, with 1743 MLD being in construction. Nevertheless, only 72.2% of the sewage is actually used, or 13.5% of the sewage is treated. The use of coagulant-aided tertiary sedimentation is highlighted as a way of improving the treatment process, particularly when the scheme integrates lime and alum in an effort to ensure a high efficiency of treatment.  This highlights the direct growth prospects of inorganic coagulants in India, like alum and ferric salts, in the municipal wastewater treatment industry to fill in the treatment gap and attain better environmental standards.

Additionally, stringent environmental regulations, awareness of water-borne diseases, and government policies like the National Water Mission are also contributing to the need for inorganic coagulants. Such coagulants as aluminum sulfate and ferric chloride are important in assisting to remove suspended solids in municipal and industrial wastewater, and in helping to maintain the standards of water quality and sustainability.

North America Market Insights

The North American market is expected to experience stable growth with a significant revenue share of 25.6% during the forecast period. The increased emphasis on sustainable practices, as well as the growing need for potable water, motivates the product addition to solve different water quality concerns while also supporting the region's commitment to environmental stewardship and resource conservation. In addition, the National Primary Drinking Water Regulations (NPDWR) of the U.S. EPA are legally binding rules and regulations used to regulate the levels of contaminants in the public water supply, including inorganic chemical compounds, to ensure the safety of the people. Such stringent regulations increase the pressure to have efficient treatment processes with the use of inorganic coagulants such as aluminum sulfate or ferric chloride, which are crucial to eliminating contaminants as well as being compliant with regulations, hence driving the inorganic coagulant market in North America.

Furthermore, the effect of climate change on the quality of source water is also increasing the need for inorganic coagulants in the region. For example, climate change has resulted in a more than 67% increase in natural organic matter (NOM) in water sources, causing a near doubling of alum dosing at two drinking water plants in Canada in 2023. Alum use increased to more than 1.1 million kg in 2023, as freshwater treatment needs and inorganic coagulant application in North America continue to increase.

The U.S. inorganic coagulants market is expected to dominate the North American region by 2035, attributed to rising demand for high-quality drinking water due to the increased standards of living and more concern with the health of the population, thus stimulating the demand for the commodity. According to the 2023 UN World Water Development Report, 46% of the world population does not have safe sanitation, and 26% does not have safe drinking water. Due to increased water pollution and scarcity, the U.S. is experiencing increased demand for inorganic coagulants, such as alum and ferric chloride, to provide high efficiency in water treatment and safety in water supply.  Additionally, the 2021 UN-Water estimates show that approximately 10 percent of the world population, about 720 million people, live in countries with high or critical water stress. This is of increasing concern to the growing requirement of inorganic coagulants in the United States, where their application in water and wastewater treatment processes is on the increase. Moreover, as reported by the UN, 2.2 billion individuals in 2024 do not have access to safely managed drinking water, and 3.4 billion do not have access to safely managed sanitation. As the world witnesses increased water scarcity and pollution, the U.S. water sector is placing more and more trust in inorganic coagulants to achieve high standards of treatment and to provide safe and clean water, thereby fueling the inorganic coagulants market expansion in the country.

The inorganic coagulants market in Canada is predicted to expand at a steady rate over the forecast years, mainly due to its rising water guidelines to avoid health issues. Aluminum finds extensive usage in drinking water, wastewater, and industrial water treatment facilities. Aluminum salts are used in drinking water treatment to eliminate organic matter, microbes, and turbidity. For example, the guideline of Health Canada specifies a maximum acceptable concentration (MAC) of 2.9 mg/L and an operational guideline of 0.1 mg/L in drinking water as the optimal concentrations of aluminum to treat water. The inorganic coagulant market is supported by the fact that aluminum salts are currently popular in Canada to coagulate and eliminate turbidity, organic matter, and microbes. In addition, according to Statistics Canada, 69.2% of surface waters and 6.7% of groundwater that is directly influenced by surface water are treated with coagulants based on aluminum. In addition to being an impurity in other chemicals used in water treatment, aluminum has been shown to leak into drinking water from cement-based materials. Additionally, by employing activated alumina to eliminate additional impurities, aluminum can be added to drinking water.
