Abstract

Aluminium sulphate (alum), ferric chloride and polyaluminium chloride (PAC) are the most
common coagulants being used for leachate coagulation-flocculation treatment. However, the impact of these
residual’s coagulants have sparked huge concern ceaselessly. Therefore, development of natural coagulant as an
alternative coagulant for treatment process has been given full attentions. In this attempt jackfruit seed starch
(JSS) which produce by extraction method was used as coagulant aid with PAC. The removal efficiency was
determined using jar test method. The removal of leachate pollutants was compared between PAC coagulant
with and without JSS. Interestingly the JSS coagulant aid has succeed to reduce the dosage of PAC from 900
mg/L to 600 mg/L by increasing the removal of COD, colour and ammonical nitrogen (NH3-N) up to 33.6%,
93.6%, and 13.1 % respectively. While the removal for turbidity and suspended solid (SS) were maintained at
94% and 92 % respectively. The addition of JSS has succeeded to reduce 33.3% the usage amount of PAC in
treatment process of landfill leachate. The result proved that JSS was effective to be used as coagulant aid
landfill leachate treatment.
