The water treatment process used to produce safe drinking water produces a large amount of residual products, depending on the untreated water source, the chemicals used for purification, and the type of unit operation used. In the conventional coagulation-filtration process, by adding aluminum and iron salts as coagulants, suspended solids and natural organic matter are removed from the raw water, resulting in water treatment residues. The residues are often disposed of in landfill after the residue being dewatered or directly discharged into urban sewage systems or surface water (without being dewatered), both of which ether increase water treatment cost or enhance the potential risks to environment. Successful recycling of the residues would be beneficial to achieve economic cycle model.
The recycling of water treatment residues has been reported to involve in various fields, including construction industry, flocculants recovery, and especially environmental remediation. The research has greatly improved our understanding of the nature, environmental behavior, and potential uses of water treatment residues. Therefore, the research topics of this special issue include but are not limited to:
- Current residual characteristics of water treatment;
- Determine the potential of water treatment residues to control pollution for protection of underground water and surface water.
- Show how water treatment residues affect microorganisms, micro-animals, insects and animals;
- Review the negative and beneficial environmental impacts of water treatment residues in water environment remediation;
- Determine the accumulation of much radioactivity in water treatment residues.
