Performance of chitosan from mushroom as biocoagulant agent for kaolin and palm oil mill effluent wastewater
This project aims to investigate the potential use of commercial chitosan produced from mushroom (CMs) as bio-coagulants which are water-soluble chitosan (WSC) and acid-soluble chitosan (ASC) in wastewater treatment. Palm Oil Mill Effluent (POME) is wastewater generated from the palm oil milling...

| description | This project aims to investigate the potential use of commercial chitosan produced
from mushroom (CMs) as bio-coagulants which are water-soluble chitosan (WSC)
and acid-soluble chitosan (ASC) in wastewater treatment. Palm Oil Mill Effluent
(POME) is wastewater generated from the palm oil milling industry must be treated
properly before being discharged into the environment. The use of inorganic
coagulants like alum can potentially lead to the spread of chronic diseases due to the
residual content of the coagulants in the treated wastewater. Thus, this study searched
for an alternative coagulant using (CMs) for coagulation process. In this study, the
optimum condition for synthetic water kaolin treatment when WSC was at pH 8, with
a dosage of 10 mg/L, and with almost 100% turbidity removal. While ASC optimum
conditions were at pH 11, dosage 10 mg/L and almost 100% turbidity removal. On the
other hands, the performances of CMs coagulants as bio-coagulants were compared to
aluminum sulphate (alum) coagulant. The results showed that alum gave 93%
turbidity removal at optimum pH 4 and with an optimum dosage of 1200 mg/L.
The treatment of POME wastewater by using CMs as a bio-coagulant was successfully
able to reduce COD with up to 73% in value, 70% of BOD reduction and 99% of TSS
removal, whereas alum coagulant resulted in 71% of COD, 65% of BOD reduction
and 86% of TSS removal. The second objective of this study was to examine the
characterization of the WSC and ASC by using Fourier Transform Infrared (FTIR)
analysis, Zeta Potential, and antimicrobial activity. The results of FTIR confirmed the
existence of amino groups in the backbone of CMs. The results of Zeta Potential
analysis showed that the surface charges for WSC and ASC were 40.46 mV ± 1.01
and +70.24 mV ± 3.69, respectively. The antimicrobial activity analysis showed that
ASC is more active than WSC where the concentration used of CMs was 10%. The
ASC was active to inhibit microbes within around 7 mm zone which is considered
clear zone of inhibition. The estimated cost for treatment using WSC, ASC and alum
was RM 5.5, 4.52 and 84 per cubic meter respectively of POME treated wastewater. In conclusion, this study has proven that chitosan mushroom possesses a significant
potential to be used as a bio-coagulant for wastewater treatment and also economical. |
