Environment-Friendly Approach toward the Treatment of Raw Agricultural Wastewater and River Water via Flocculation Using Chitosan and Bean Straw Flour as Bioflocculants

Antimicrobial Actions and Applications of Chitosan

“…Due to its several unique properties, including biodegradability, biocompatibility, and low toxicity, chitosan has been extensively investigated for applications in many fields. For example, chitosan has been used as a flocking agent in water treatment [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ], an elicitor to activate plant defenses [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ], a supplement during food preservation and in food additives [ 38 , 39 , 40 , 41 , 42 , 43 , 44 ], a dehydrating agent in cosmetics [ 45 , 46 , 47 , 48 , 49 , 50 , 51 ], and a drug delivery carrier [ 52 , 53 , 54 , 55 , 56 , 57 , 58 , …”

Remediation of Emerging Contaminants

“…It is now recognized that the presence in aquatic environments is mainly correlated with the discharge of effluents from municipal wastewater treatment plants (Fig. 1.1), with a higher incidence in wastewater treatment plants in highly industrialized and urban areas (Sole et al 2000;Goméz et al 2006;Stackelberg et al 2007;Kasprzyk-Hordern et al 2008;Watkinson et al 2009;Basile et al 2011;Gonzalez et al 2012;Meffe and Bustamante 2014;Machado et al 2016;Morin-Crini and Crini 2017;Priac et al 2017;Gilabert-Alarcón et al 2018;Mezzelani et al 2018;Picos-Corrales et al 2020). However, environmental contamination/pollution originates not only from domestic activity but also from the industrial and agricultural sectors, and other activities such as transport (Morin-Crini and Crini 2017).…”

Emerging Contaminants: Analysis, Aquatic Compartments and Water Pollution

“…1.8) (Osuna-Flores and Riva 2002;Arellano-Aguilar et al 2017). In particular cases, people of various villages are in contact with this type of hazardous leachates; furthermore, private wells for drinking water, which is untreated (used directly), are located close to agricultural fields (Picos-Corrales et al 2020). In this regard, some pesticides are regulated in Mexico by the Federal Commission for the Protection against Sanitary Risk, an organ of the Health Secretary of Mexico.…”
