Sonochemical Based Processes for Treatment of Water and Wastewater
AI summary Read the abstract
This book chapter reviews sonochemical processes -- using ultrasound to generate reactive species -- as an emerging technology for treating organic contaminants including pharmaceuticals, pesticides, and microplastics in water and wastewater.
As a result of rapid socio economic advancement, industrialization, and population growth, a substantial amount of organic contaminants are continuously being discharged into wastewater triggering severe environmental concerns (Hube and Wu 2021, Oliveira et al. 2022, Ribeiro et al. 2022, Zhang et al. 2022). The occurrence of various organic contaminants such as phenols, pesticides, dyes, pharmaceuticals, microplastics, plasticizers, and other industrial chemicals have been reported in water resources. Such pollutants may cause stress on the aquatic ecosystem as well as are a risk to human health and elevate a plethora of environmental issues (Agarkoti et al. 2021, Bernabeu et al. 2011, Hammouda et al. 2017, Montoya-Rodríguez et al. 2020, Serna-Galvis et al. 2022, Wiest et al. 2021).
