Manufacturers of chemicals for water and wastewater treatment are instrumental in the quality, safety, and sustainability of water systems for industrial and municipal purposes. They manufacture innovative chemical solutions that address a range of treatment applications, including coagulation, flocculation, disinfection, corrosion mitigation, and sludge conditioning. Their development of highly effective coagulants and flocculants optimizes suspended solids and organic matter removal, which results in improved clarity of water and lower operational costs downstream.
The global chemical manufacturing market was valued at around $6.2 trillion in 2023, with projections suggesting it reached approximately $6.3 trillion in 2024, and is expected to continue growing to over $6.3 trillion by 2025. Along with physical purification, companies that produce chemicals also offer several biocides and oxidizing agents to control microbial growth and biofouling in pipelines, tanks, and filtration systems.
Our subscribers play a decisive role in finalization of our annual list of "Top 10 Chemical Manufacturers for Water & Wastewater Treatment Plants - 2025" by recommending those which have served them with excellence and are praiseworthy.
