Regulatory mandates on wastewater treatment
Regulations have been implemented by regulatory authorities such as the Environmental Protection Agency (EPA), the Clean Water Act (CWA), the Safe Drinking Water Act (SDWA), and other similar organizations to restrict industrial discharge and guarantee adequate wastewater treatment. These rules have increased the need for wastewater treatment chemicals. Increased regulatory demands have required the industry to meet stringent effluent quality standards. To satisfy these criteria and limit the environmental impact of their activities, they must build effective wastewater treatment technologies.
This has generated a significant market potential for water treatment chemical producers such as Kemira OYJ (Finland) and BWA Water Additives (UK), both of which specialize in delivering chemicals for industrial wastewater treatment. The Wastewater Effluent Regulations created under the Fisheries Act emphasize the importance of adequate wastewater treatment even more. These laws establish minimal effluent quality criteria that businesses must meet to safeguard aquatic environments. To meet these criteria, wastewater treatment chemicals must be used to eliminate pollutants and toxins from industrial wastewater. Such regulatory mandate on wastewater treatment drives the growth of the market.
The rise of alternative water treatment technologies
Physical water treatment methods such as UV disinfection and reverse osmosis (RO) filtering are replacing the usage of water treatment chemicals in the water treatment sector. These environmentally friendly solutions are in line with growing environmental concerns and government laws, resulting in a gradual transition away from chemical-intensive water treatment techniques. RO technology is a popular water purification method that uses a semi-permeable membrane to remove big particles and dissolved contaminants from water. UV radiation is used to disinfect water by attracting and killing microorganisms such as bacteria and viruses.
RO filtration lowers reliance on water treatment chemicals since the physical filtering process is sufficient to satisfy acceptable water quality requirements. UV disinfection technology has also gained popularity in water treatment as an alternative to chlorine-based biocides. Due to its efficacy, environmental friendliness, and advocacy of its usage by regulatory organizations such as the Environmental Protection Agency (EPA), this technique has been extensively embraced. Since UV disinfection does not need the use of chemicals, it decreases the dependency on water treatment chemicals in the disinfection process even more. Such alternative methods hamper the growth of the water treatment chemicals market.
Utilization of the 3R method of sustainability
The adoption of a more sustainable approach through reducing, recycling, and reusing activities represents a substantial opportunity for the wastewater treatment chemicals industry. To begin with, the idea of reduction refers to using fewer resources in the first place. There is a direct positive influence on wastewater generation by lowering the use of water and other resources in industrial operations. Water-saving strategies, efficient manufacturing processes, and process optimization can minimize wastewater volumes, lowering the requirement for wastewater treatment chemicals.
The reuse of treated wastewater represents a huge market potential for wastewater treatment chemicals. Industries may reduce their dependency on freshwater sources, save water resources, and limit wastewater discharge into the environment. As a result, there is an increased need for specialized wastewater treatment chemicals that allow for the safe and effective treatment of wastewater for reuse.
Recycling procedures might include recovering valuable chemicals, nutrients, or energy from wastewater, which necessitates the employment of particular chemicals and treatment methods. Implementing the three Rs in wastewater treatment not only corresponds with sustainable practices but also provides companies with financial savings and resource optimization. As enterprises increasingly value environmental stewardship and resource efficiency, there is a rising market need for wastewater treatment chemicals that support these long-term goals.
The coagulants and flocculants segment held the dominating share in 2023, the segment will continue to grow while sustaining its lead throughout the forecast period. The coagulants and flocculants play a crucial role in the removal of impurities and pollutants from water, making it suitable for various applications, they are extensively used in municipal water treatment plants, industrial processes and water treatment facilities in residential areas.
Another major factor for the segment’s dominance is the application of coagulants and flocculants for the treatment of drinking water. Moreover, stringent regulations on water quality testing boost the demand for flocculants and coagulants globally.
The oil and gas segment is expected to hold the dominating share of the market. The financial capacity of the oil and gas companies allows them to invest significantly in advanced and specialized water treatment technologies, including chemical solutions. This enables them to address complex water treatment challenges effectively.
Large refineries and petrochemical plants require a significant volume of water to be treated on a continuous basis. The sheer scale of operations within the oil and gas industry contributes to substantial demand for water treatment chemicals. Industry often involves the extraction of crude oil from remote and challenging environments, where water sources might be contaminated. This factor also brings a requirement for water treatment solutions for the oil and gas industry.
The raw water treatment segment held the largest revenue share in 2023, the segment is anticipated to continue the trend throughout the forecast period. Raw water is generally sourced from rivers, lakes, and groundwater. This water often contains a plethora of impurities and microorganisms. Water treatment chemicals play a vital role in this process by facilitating the purification, disinfection and stabilization of raw water. The consistent demand for clean and safe water across agriculture, power generation and manufacturing sectors drives the need for effective raw water treatment solutions.
