Area of Science:

  • Environmental Science
  • Water Treatment Technologies
  • Adsorption Processes

Background:

  • Fluoride contamination in aqueous solutions poses environmental and health risks.
  • Alum sludge, a byproduct of water treatment, is explored as a potential adsorbent for contaminant removal.

Purpose of the Study:

  • To investigate the efficacy of treated alum sludge in removing fluoride from aqueous solutions.
  • To determine the optimal conditions and understand the adsorption mechanism for fluoride removal.

Main Methods:

  • Batch adsorption experiments were conducted varying contact time, adsorbent/adsorbate concentration, temperature, and pH.
  • The influence of competing anions on fluoride removal was assessed.
  • Adsorption data were analyzed using Langmuir isotherm and first-order kinetics models.

Main Results:

  • Treated alum sludge demonstrated significant fluoride removal capabilities.
  • The optimal pH for fluoride removal was determined to be 6.
  • Adsorption equilibrium was reached within 240 minutes, following first-order kinetics and the Langmuir model.
  • Fluoride loading increased with initial concentration but decreased with rising temperature.

Conclusions:

  • Treated alum sludge is a viable and effective adsorbent for removing fluoride from water.
  • The adsorption process is influenced by solution chemistry, including pH and the presence of other anions.
  • Understanding the adsorption kinetics and isotherm models provides insights for optimizing water treatment processes using alum sludge.
