Impactful Driver: Technological Advancements

The global demand for chemically treated water is on the rise as only 2.5% of the world’s water is freshwater, posing challenges for industries and households. To address this scarcity, water treatment chemicals play a crucial role in efficient water recycling. Industries including oil & gas, power, pulp & paper, mining, chemicals, and food & beverage are rapidly adopting treated wastewater.

Growing economies like China, India, Brazil, Indonesia, Malaysia, Argentina, Chile, and Vietnam are witnessing an increased demand for clean water across homes, farms, and industries, with water treatment chemicals proving to be a cost-effective solution compared to methods like ion exchange, UV filtration, and reverse osmosis. Notably, coagulation, flocculation, and disinfection costs in large water treatment plants are considerably lower than UV and RO alternatives.

The expansion of power, oil & gas, mining, and chemical industries, particularly in regions such as China and India, is a key driver for the heightened demand for these chemicals. Major projects like Brazil’s pre-salt oil fields and the global construction of high-capacity power plants using fossil fuels, nuclear, or solar power further contribute to the growing market for water treatment chemicals.

Restraining Factors

Emerging water treatment technologies are gaining popularity due to their eco-friendly and cost-effective nature, contributing to a slowdown in the traditional water treatment chemicals market. Membrane filtration systems, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, offer precise contaminant removal without the use of chemicals, enhancing water quality and reducing reliance on traditional additives.

Ultraviolet (UV) disinfection is another environmentally friendly method that eliminates pathogens without chemical intervention, addressing environmental concerns and reducing the costs associated with purchasing and disposing of conventional treatment chemicals. The adoption of these advanced and sustainable water treatment methods aligns with industry efforts to prioritize environmental conservation and cost efficiency, potentially impacting the growth of traditional water treatment chemical markets.


The water treatment chemicals market is presented with significant opportunities in the Asia Pacific region, particularly in China and India, driven by a rising population and rapid urbanization. China, facing water scarcity and a large population, emphasizes water quality in its Five-Year Plan for Ecological & Environmental Protection. The government’s initiatives to manage water quality, control pollution, and enhance urban water bodies create a robust demand for water treatment chemicals.

Similarly, India, with a substantial population and limited freshwater resources, showcases a clear need for clean water in agriculture and industries. With 16% of the world’s population, India represents a substantial market for water treatment solutions. As urbanization progresses and environmental concerns heighten, these countries offer significant opportunities for the water treatment chemicals industry to address water quality challenges and meet the escalating demand, marking an exciting period for industry growth.


The water treatment chemicals market faces a significant obstacle due to stringent environmental regulations, particularly from agencies like the EPA, necessitating eco-friendly formulations. Concerns over the environmental impact of chemicals have resulted in stringent rules for companies in this sector. While the industry is pushed towards adopting greener options, challenges arise as these alternatives may not perform as effectively in demanding conditions.

Manufacturers grapple with the economic aspects of green chemistry, making it challenging to develop both effective and economically friendly water treatment chemicals. The shift to green alternatives introduces the risk of bio-fouling, requiring additional biocides that impact cost-efficiency. Striking a balance between the need for stronger formulations for enhanced recycling and environmental considerations poses a complex challenge. Moreover, the vulnerability of patented water treatment chemicals to replication presents a significant issue, with counterfeit products from certain Asian manufacturers undermining basic chemical makers in the market.

Regional Analysis

In 2023, North America dominated the water treatment chemicals market with over 32.2% market share, driven by the surge in unconventional sources like tight oil and shale, particularly in North Dakota and West Texas, spurred by hydraulic fracturing. The increased presence of water treatment plants in the upstream oil and gas sector in response to this trend is expected to positively impact the market in the forecast period.

The U.S. is anticipated to experience a 2.4% compound annual growth rate (CAGR) over the forecast period, attributed to stringent regulations governing wastewater disposal and production. The country’s leadership in energy production and the growing demand for water treatment chemicals in the power industry, especially in thermoelectric power plants, will further contribute to market growth.

In Asia Pacific, the demand for boiler chemicals is set to rise, driven by increased manufacturing, industrial activities, and growth in the power sector. China, facing high levels of heavy metals and suspended particles, is actively seeking pretreated water. Organizations like China Water Risk (CWR) play a crucial role in reporting on the risks and impacts of wastewater in China’s key industries, contributing to water treatment efforts and addressing associated challenges.
