Abstract |
: |
Saudi Arabia is considered one of the largest producers of dates in the world, as result of consuming these dates, large quantities of waste was produced (date seed), which is considered one of the materials that contain carbon and as such could be used as a carbonic material with good adsorption capabilities of pollutants. One of these pollutants are Polycyclic Aromatic Hydrocarbons (PAHs) and they are organic compounds which are carcinogenic, bio-accumulative, and do not break down easily in the environment. Accordingly PAHs could enter a wastewater treatment plant either as part of an industrial discharge, or as a component of domestic effluent drainage into the sewerage system and urban runoff. The objective of this study is exploring the possibility of utilizing date seed waste to produce Granular Activated Carbon (GAC) in order to remove PAHs and specifically acenaphthene, anthracene and naphthalene by adsorption from water phase which has not been done before. Development and application of activated carbon from Date Seed is a sustainable solutions as it is considered locally available cheap/waste material. This study consists of three phases. Firstly, GAC was prepared from Date Seeds. Secondly, removal of acenaphthene, anthracene and naphthalene is done where the batch experiments were setup to determine adsorption capacities of applied materials. Finally after obtaining the results, Rapid Small-Scale Column Test (RSSCT) were conducted on naphthalene only and from which design parameters for large-scale system were determined. In the batch experiments, it is demonstrated that GAC prepared from date seed was superior to commercial GAC in removing acenaphthene and naphthalene (34 % and 46 % respectively), however it was marginally better in removing anthracene (3%). In RSSCT, the date seed GAC produced in this study lasted 3.23 days and treated 53 L of water containing naphthalene until breakthrough was achieved using only 2.4 g of date seed GAC. After upscaling RSSCT, this translated to 232.48 days and approximately 1.4 million liter of water containing naphthalene can be treated before exhaustion of the GAC bed using approximately 93 kg of Date Seed GAC. Taking this into consideration combined with the relative simplicity of producing Date Seed GAC prepared in this study, it can be utilized as an alternative to currently available commercial GAC in the market for the removal of acenaphthene, naphthalene and even anthracene. |
