Ammonia-nitrogen removal from urban drainage using modified fresh empty fruit bunches: A case study in Kota Kinabalu, Sabah

[摘要] Highly concentration of ammonia nitrogen in urban drainage could pollute the river and give pungent smell. The strong pungent odours that coming out from the urban drainage may degrade the image a city and could possibly reduce the present of tourist. To minimize the presence of pungent odours, the ammonia nitrogen can be removed from the urban drainage by applying proper adsorbent. In this study, an adsorbent produced through chemical modification of fresh empty fruit bunch (EFB) fibers has been carried out. The maximum adsorption capacity is between 0.01-0.60 mg/g. The finding also shows that the retention time is vital when designing ammonia nitrogen filter.
