Biological Treatment of Organic Waste in Wastewater—Towards a Circular and Bio-Based Economy

Abstract

Due to population growth, accelerated urbanization, and economic development, the quantity of both industrial and urban wastewater generated, and its overall pollution load are increasing globally [...]

Green synthesis and environmental applications of alginate/polyacrylamide/titanium dioxide composite hydrogel

“…1,2 With the rapid growth of the population, accelerated urbanization, and economic development, industrial and municipal wastewater generation is increasing. [3][4][5] Organic dye wastewater discharged from the printing and dyeing industry in particular has caused serious harm to the natural environment, leaving the treatment of wastewater as an issue of great concern. [6][7][8] Currently, many methods have been probed to remove the dyes from water, including adsorption, [9][10][11] membrane separation, [12][13][14] extraction, 15 and biological methods.…”

“…Although most of the earth's surface is surrounded by water, only a small amount of freshwater resources are available for daily drinking, agricultural irrigation, and industrial production 1,2 . With the rapid growth of the population, accelerated urbanization, and economic development, industrial and municipal wastewater generation is increasing 3–5 . Organic dye wastewater discharged from the printing and dyeing industry in particular has caused serious harm to the natural environment, leaving the treatment of wastewater as an issue of great concern 6–8 .…”
