Previous research shows that although alum is effective as a coagulant in wastewater
treatment, it may also deteriorate health over a long period of time. Activated carbon
(AC) from biodegradable materials has shown promising results. The purposes of this
research are to prepare AC from Nephelium lappaceum (NL) seeds in different sizes
and determine the efficiency in reducing turbidity in synthetic wastewater. The AC was
prepared in powdered form with different sizes (1mm,2mm,4mm) followed by 3
varying heating durations. The AC was tested in synthetic wastewater sample made
from kaolin to investigate the effectiveness of different sizes and heating durations of
the AC as a water treatment system. Characterization of the AC was done using FTIR,
XRD, BET, and SEM to determine the functional groups, structural state, surface area,
and morphological analysis respectively. A further study regarding the combination of
conventional AC and NL should be conducted.
