Aerobic Treatment And Biodegradation Of Palm Oil Mill Effluent By Indigenous Microorganisms.
PhD thesis, Universiti Sains Malaysia.
Abstract
Biodegradasi mikrob air buangan yang melibatkan penggunaan pelbagai mikroorganisma telah menunjukkan keupayaan degradasi sisa organik dalam air sisa yang berkesan yang telah menarik perhatian sejak kebelakangan ini. Kajian ini bertujuan untuk menentukan keupayaan biodegradasi oleh mikroorganisma- mikroorganisma asli yang dipencilkan daripada efluen kilang minyak kelapa sawit (POME) sebagai substrat untuk mengurangkan keperluan oksigen biokimia (BOD5), permintaan oksigen kimia (COD), jumlah pepejal terampai (TSS) dan minyak dan gris (O & G) daripada POME dan untuk mengenalpasti strain yang paling sesuai untuk teknologi rawatan biologi POME dalam keadaan aerobik. Pencirian sampel POME telah dijalankan mengikut kaedah-kaedah piawai untuk pemeriksaan air dan air sisa.
Microbial biodegradation of wastewaters involving the application of variety of microorganisms has demonstrated effective degradability of organic wastes in wastewaters which has attracted attention in recent time. This study was designed to determine the biodegradation ability of indigenous microorganisms isolated from palm oil mill effluent (POME) as substrate for the reduction of biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total suspended solids (TSS) and oil and grease (O & G) from POME and to identify the most suitable strain(s) for a biological treatment technology of POME under aerobic condition. The characterization of POME sample was carried out according to standard methods for the examination of water and wastewater.
