Coagulants and Natural Polymers: Perspectives for the Treatment of Water

並列摘要


The waste generated by modern society, when discarded in nature can make the water unfit for human consumption. Thus to obtain drinking water is necessary to perform a physical-chemical treatment, which allow the removal of the turbidity and organisms harmful to health. These coagulant chemicals and related products, although efficient, physical and chemical characteristics of water, complicate the disposal of sludge generated, and make the water have a high cost, which is passed on to consumers. In view of the replacement or Reduction of chemical coagulants used in water clarification, natural polymers and coagulants are effective, productive, free from physical and chemical changes in the treated water, and add value to their sources of origin. In this perspective, this review encompasses the most natural products Studied and Reported in the scientific and applied in water treatment.
