Process By Equipment Insights

The tertiary treatment segment dominated the market with a revenue share of 44.5 % in 2025. Tertiary treatment is the final stage in water and wastewater treatment, designed to refine the treated water to meet stringent quality standards before discharge or reuse. This stage often involves advanced filtration, chemical treatment, or disinfection methods, such as UV treatment or membrane filtration, to remove remaining contaminants, including pathogens, heavy metals, and nutrients, that were not removed during earlier stages. Tertiary treatment is becoming increasingly important as regulations on water quality become more stringent, and the demand for water reuse, particularly in the industrial and municipal sectors, continues to rise. It helps ensure that water is safe for various purposes, including irrigation, industrial processes, or even potable reuse.

Secondary treatment is the biological phase of water and wastewater treatment, where the focus is on removing dissolved organic matter and suspended solids through microbial action. In this stage, activated sludge processes or trickling filters are commonly used, where microorganisms break down organic pollutants in the wastewater. Secondary treatment is a crucial step in reducing biochemical oxygen demand (BOD) and suspended solids, thereby ensuring that the water meets basic quality standards for discharge into natural bodies of water. This treatment stage is crucial for municipal and industrial wastewater management, as it plays a significant role in mitigating the environmental impact of wastewater before it undergoes further refinement in tertiary treatment.

Application Insights
