Leachate filtration by using low cost material / Farahdilla Ahmad Fauzy

Filtration is a mechanism by which leachate constituents are physically trapped.
Filtration efficiency depends on pore size and hydraulics gradients of the leachate. The
main purpose of this Final Year Project is to remove the parameter of COD, SS, pH,
conductivity, Iron (Fe) and Manganese (Mn) in leachate. This treatment is important to
ensure that the values of parameter are fulfilling the Environment Quality (Sewage and
Industrial Effluents) Regulation, 1979 based on maximum effluent parameter limits
Standard A and B. This treatment is a pre-treatment of leachate where we use the crush
stone and charcoal as a filtration media at different diameter. The sample that be used in
this treatment is a leachate from landfill Idaman Bersih Sdn Bhd (IBSB) at Sg Burong.
In order to fulfill the objective of this study, one of the experiment will carry on, whish
using the low cost material to obtain the values of parameter COD, SS, pH, conductivity,
Iron (Fe) and Manganese (Mn) of sample before(influent) and after(final effluent)
treatment. Comparison between influent and final effluent parameters will be taken to
evaluate the effectiveness the crush stone and charcoal as a filtration media. This
medium can remove the parameters such as SS up to 80%, Conductivity up to 52% and
Manganese up to 56.25%. The results show the removal a percentage is influence by
detention time and size of filtration media. The removal percentages of these parameters
were better for 5 hours detention time. The filtration process will be done by using the
same filtration media without backwashing process.
