- •
Antibiotic removal from wastewater using CWs is greatly affected by substrate type.
- •
Surface soil and selected substrates behaved differently to OTC and DIF adsorption.
- •
Variation of ARG relative abundances are determined by hydraulic flow direction.
- •
Most ∑tet relative abundances were amplified in effluents of up-flow treatments.
