| dc.description.abstract | The water washing pretreatment on empty fruit bunches (EFB) of oil palm waste has been investigated in this study, with the objective of removing some ash from the EFB to improve the quality of biomass. This study also investigated the effectiveness of water washing to remove ash by changing the appropriate parameters of the water washing pretreatment such as residence time, amount of water, type of water and use of soaking and stirring. Tap water and distilled water were solely used throughout the work. The original ash content for the unwashed EFB is 5.19 mf wt%. From this study, the average ash content of the washed EFB by soaking the feedstock of size 1-3 cm in 3 l of tap water for 5 min residence time at ambient temperature is found to be 2.95 mf wt%. It is found that the ash content less than about 3 mf wt% was successfully achieved. It also showed that tap water is as effective as distilled water in reducing ash in EFB. The electrical conductivity in waste liquor by soaking the feedstock for 5 min at ambient temperature in 3 l of tap water was 991 μS/cm and it was increased with the prolonged soaking time. The electrical conductivity in waste liquor was found to increase due to the diffusion of mineral and inorganic materials from biomass. | en_US |
