  • Can alum sludge be used as a drinking water treatment residual?
  • Li et al. ( 2016) investigated the alum sludge as a drinking water treatment residual which containing polyaluminum chloride and large amount inorganic matters. Chemical conditioner and physical conditioner for improved the sewage sludge dewatering (Tony 2025a ).
  • Does alum recover from water treatment residues?
  • No doubt, alum recovering from water treatment residues is minimizing the environmental impacts that could be caused by Al-sludge and also minimize the cost through purchasing alum since the recovered alum may be applied for numerous times (Sanga et al. 2018 ).
  • Can alum sludge be used for phosphorus removal?
  • Reuse of alum sludge for phosphorus removal from municipal wastewater. Desalination and Water Treatment, 57, 13246–13254. Matilainen, A., Vepsäläinen, M., & Sillanpää, M. (2010). Natural organic matter removal by coagulation during drinking water treatment: a review. Advances in Colloid and Interface Science, 159, 189–197.
  • Can alum sludge be recycled?
  • Recovery of Al from alum sludge for the option of recycle, reprocess and reuse in order to reduce waste still needs further work data for the full-scale possibilities of coagulant reuse. It is noteworthy to mention that, presently, potential future technologies are required for recovery technologies (Keeley et al. 2014 ).
