Scholarcy highlights

  • Algal-bacterial process biotechnology is a recent low-cost method toward toxic pollutant removal from wastewater that has received more attention in the present scenario
  • The water pollutants mainly include SO2 from power plants, chemical waste, fertilizers from agricultural use, oil spillage, silt, harmful pesticides, detergents, harmful compounds in cosmetics, pathogenic bacteria from livestock operations and food processing wastes, and chemical compounds found in cosmetics products, effluent outfalls from factories, refineries, waste treatment plants, contaminants from improper disposal of industrial wastes running through rainwater, etc
  • The harmful dissolved methane in anaerobically treated wastewater can effectively be treated by the methane-oxidizing bacteria and algae
  • It can be concluded that the conventional algal-bacterial system treatment technology acts as a natural biological treatment method as a viable alternative and is of great importance for achieving good wastewater treatment performance as well as the reduction in energy consumption cost
  • Wikfors G, Ukeles R Growth and adaptation of estuarine unicellular algae in media with excess copper, cadmium or zinc, and effects of metal-contaminated algal food on Crassostrea virginica larvae
