Tags: , , , ,
  • Why is adsorption used in water treatment?
  • Adsorption is currently used for water treatment purposes because of the following advantages: low-cost, high efficiency, ease of operation, ease of implementation, the possibility to use several solids as adsorbent materials, and the possibility to recover the adsorbent and the adsorbate [ , , , ].
  • What are the disadvantages of adsorption method?
  • Some drawbacks of the methods are: low removal efficiency, high production of sewage sludge, non-cost-and-energy efficiency, generation of toxic by-products, as well as the addition of more potentially toxic chemicals into the environment. Adsorption method has been found to be the most effective and economical process.
  • What are the challenges in adsorption kinetics for water treatment?
  • In conclusion, interesting challenges in adsorption kinetics for water treatment are the development and application of diffusional models for multicomponent systems and the development of correlations to estimate the surface diffusion coefficient.
  • Should adsorbents be used for wastewater treatment?
  • Although the available literature on the use of adsorbents for wastewater treatment is increasing at a tremendous pace, there are still several gaps which need more attention. More selective, efficient, inexpensive, reusable and eco-friendly adsorbents should be developed and experiments be conducted with real industrial effluents.
