This research investigated the removal efficiency of burned (activated) blood cockle
shells (BBCS) of the total nitrogen (N) and phosphorus (P) effluent from shrimp farms, in
comparison with novel activated charcoal (AC) and natural (unactivated) blood cockle shell
(grinding, NBCS). All shell types (BBCS, NBCS) performed well as adsorbents The removal
efficiency varied with shell particle size and effluent flow rate. The shell particle size of BBCS
at 0.85-2.0 millimeters had the highest removal efficiency of total N and P at 86.66% and
87.63%, respectively. The best flow rate of effluent for N and P removal efficiency through
adsorbency were 300 ml/hour. Moreover, the equilibrium model study for adsorption isotherm
of BBCS performed better fitted to the Langmuir model in nitrogen removal, and to both
Langmuir & Freundlich model in phosphorus removal. Our findings indicated that the higher
surface area and larger average pore size of the adsorbents as BBCS (Bunauer, Emmett and
Teller method: BET) produced more N and P removal efficiency than the lower one as NBCS.
