文摘
- •
Lower fractions of raw (NOS)/calcined (COS) oyster shells removed P from saltwater.
- •
Oyster-shell calcination boosted P removal (95%) from saltwater after 15 min.
- •
Adsorption (for NOS) and a co-mechanism of precipitation (for COS) was suggested.
- •
NOS and COS removed P up to the permitted levels for effluent discharge.
- •
OS waste is a sustainable recyclable biomaterial for marine RAS effluent treatment.
