Implication

This approach demonstrates high removal efficiencies of linear alkylbenzene sulfonate in wastewater, highlighting effective biological treatment methods.

Key Points

Removal efficiencies greater than 80% for anionic surfactants were achieved after 48 hours of operation.
Initial linear alkylbenzene sulfonate concentrations ranged from 17.51 to 41.89 mg L-1 in the sequential batches.
Polymeric hydrochar was characterized by an average diameter of 0.715 mm and low specific surface area.
The hydrodynamic tests indicated a minimum fluidization velocity of 0.49 cm-1, essential for successful operation.
