| description |
Poor management of landfill would accompany with the production of leachate
wastewater that would lead to environmental and public hazards. Hence, a study
related to the use of biological treatment for leachate management was carried
out.The research objectives of this research study were pathogenic microorganism
detection, raw leachate wastewater characterization and identification of effective
leachate treatment. A leachate sample was collectedfrom both Simpang Renggam
Landfill and Bakri Landfill via compositing sampling method.The leachate sample
was collected from two sampling points at the leachate drain. Selective selection and
serological test had been carried out and the microorganism detected in the leachate
samples were Escherichia coli, Staphylococcussp and Listeriasp.Triplicate samples
of each raw leachate wastewater were used for leachate characterization. The
parameters used for leachate characterization were chemical oxygen demand
measured via Reactor Digestion method and ammonia nitrogen concentration
measured via Nesslerization method. Besides that,the heavy metals content in the
leachate sample were measured via Atomic Absorption Spectroscopy. The ammonia
nitrogen concentration and chemical oxygen demand in the raw leachate samples
show that both leachate samples were characterized as mature leachate. Brevibacillus
panacihumi strain ZB1 was used for biological treatment and lightweight aggregate
was used for adsorption process. Triplicate of each leachate samples were treated via
sole biological treatment, combined dilution with biological treatment and combined
adsorption with biological treatment. Removals of ammonia nitrogen from both
Simpang Renggam and Bakri leachate samples treated by three treatments were
nearly37% to 47%, 63% to 77% and 83% while chemical oxygen demands removed
were 37% to 42%, 63% to 75% and 41% to 74%, respectively. Although final
concentration of pollutants after treatment processes exceeded the discharge standard,
all treatment methods proved able to reduce the pollutants concentration. |
