Recent Advances in Wastewater Treatment
This article discusses recent advances in analytical techniques, wastewater characterization, and disinfection systems for wastewater treatment.
Improved analytical techniques have allowed scientists and engineers to detect more contaminants in water supplies, including trace compounds and microorganisms that can potentially cause adverse health effects.
Wastewater characterization is increasingly important due to changing wastewater characteristics and stricter limits on wastewater discharges. Fractionation of organic nitrogen, chemical oxygen demand (COD), and total organic carbon into soluble and particulate constituents is now used to optimize the performance of biological treatment plants.
The development of new technologies, such as ultraviolet (UV) radiation, has also affected the design of disinfection systems. UV radiation is a more effective and safer disinfectant than chlorine, and it is becoming increasingly popular for use in wastewater treatment.
