- •
Engineered river bank filtration was tested with 6 days retention time.
- •
Organic matter and disinfection by-product precursor removal ranged from 40 to 90%.
- •
Alternating oxic and anoxic conditions increased overall performance.
- •
High dissolved oxygen availability favours C-DBP precursor removal.
- •
Prolonged anoxic phases favour N-DBP precursor removal.
