| Abstract |
Biochar can be made from agricultural waste products and can be used as a low-cost adsorbent
targeting dissolved organic matter (DOM). In water treatment plant (WTP) operation, DOM causes
undesirable taste and odor in water. The objective of this study was to investigate the applicability of
bamboo biochar derived from waste char from wood vinegar production as an adsorbent for DOM removal.
Raw biochar (BCRaw) and 800°C post-heated biochar (BC800) was tested for its surface characteristics
including scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and
Brunauer, Emmett and Teller (BET) analysis. The post-pyrolysis treatment increased the surface area of the
biochar from 90.3 to 274 m2/g. Batch experiments were conducted to evaluate performance of the two biochars
using raw water collected from Tapra WTP, Khon Kaen, Thailand, which uses the Chi River as its water
source. BC800 had higher DOM removal compared to BCRaw. The adsorption capacities at 24-h equilibrium
(Qe) of BCRaw and BC800 were 0.148 and 0.551 mg-C/g adsorbent, respectively. The adsorption kinetics were
described well with a pseudo-second order model, which implied chemisorption and multiple adsorption
mechanisms. Fluorescent excitation-emission matric (EEM) spectroscopy was employed to characterize
DOM before and after treatment with biochars. BC800 achieved greater removal of terrestrial humic-like and
fulvic-like DOM, due to the presence of oxygen functional groups, which enhances removal capacity for
aromatic compounds. Overall, this study shows the potential use of bamboo biochar derived from waste
materials as an adsorbent for DOM removal. |
