The chemical industry creates an immense variety of products. Manufactured chemicals have the potential to impact the ecosystem and human life. The chemical manufacturing process typically requires large volumes of chemicals, materials, and substances that are used throughout process operations. Waste streams generated in these industries can be heavily laden with contaminants, toxins, nutrients, and organic content, presenting unique challenges in terms of treatment, especially as regulations become more stringent.

Online monitors or offline analyzers can be used in the chemical manufacturing industry to provide real-time data on the presence of inorganic or trace metal contaminants during the treatment process or in the finished wastewater.
