The Performance Of Silica Sand For Leachate Treatment

Kebanyakan olahan larut lesapan yang biasa adalah dengan menggunakan kaedah yang biasa digunakan dengan karbon teraktif dan zeolit disebabkan dengan ciri-ciri bagusnya luas permukaan, tinggi kapasiti penjerapan, mikro poros kapasiti dan keistimewaan reaktiviti. Walaubagaimanapun, di dalam kajian ini...

Civil engineering (General) TP Chemical Technology Kebanyakan olahan larut lesapan yang biasa adalah dengan menggunakan kaedah yang biasa digunakan dengan karbon teraktif dan zeolit disebabkan dengan ciri-ciri bagusnya luas permukaan, tinggi kapasiti penjerapan, mikro poros kapasiti dan keistimewaan reaktiviti. Walaubagaimanapun, di dalam kajian ini, pasir silika dipilih sebagai media penjerap untuk mengolah larut lesapan disebabkan kesenangan untuk didapati dan kos yang tidak terlalu tinggi. Keupayaan pasir silika sebagai penjerapan media dilakukan dengan melihat keupayaannya untuk menyingkirkan COD, warna, nitrogen ammonia, iron dan zink daripada larut lesapan. Di dalam ujikaji kelompok, kelajuan aruhan optima, pemendapan optima dan kadar media optima yang didapati adalah 90 minit, 60 minit dan 80 g. Peratusan penyingkiran untuk COD adalah yang tertinggi iaitu 52.83% di dalam kajian pengaruh kelajuan aruhan, 55.82% di dalam pengaruh pemendapan dan 67.92% di dalam pengaruh kadar media yang digunakan. Di dalam penjerapan data oleh Freundlich Isotherm, nilai R2 adalah lebih tinggi daripada Langmuir Isotherm. Masa sentuhan hamparan kosong (EBCT) yang didapati daripada kajian ialah 15.5 minit. Kajian juga mendapati rekabentuk loji penyingkiran dengan keluasan 1 m2 dan tinggi 1.5 m adalah berkesan untuk menyingkirkan iron dengan kadar aliran 50m3/d dalam masa 23 bulan. More than a few study of leachate treatment have been done by conventional method such as by using activated carbon and zeolite due to their great surface area, high adsorption capacity, micro porous structure and special reactivity. However in this study, silica sand is chose as an adsorption media to treat leachate because of the availability, easily to be found and low cost media. The performance of silica as adsorption media is conducted by look at the potential of it to remove COD, colour, ammoniacal nitrogen, iron and zinc from landfill leachate. In batch study, optimum shaking, settling and adsorbent dosage were 90 minutes, 60 minutes and 80g. The percentage removal for COD is highest where it gets 52.83% in the effect of shaking time, 55.82% in the effect of settling time and 67.92% in the effect of adsorbent dosage. The equilibrium adsorption data followed the Freundlich Isotherm which indicate by most R2 value is higher than Langmuir Isotherm. The Empty Bed Contact Time (EBCT) found from the study is 15.5 minutes. The study showed that the design of removal plant by 1m2 and 1.5 m depth is effective to remove iron at a flow rate of 50m3/d in duration of 23 months. 2009-06 Thesis http://eprints.usm.my/35994/ http://eprints.usm.my/35994/1/EZLINA_BINTI_OTHMAN_THE_PERFORMANCE_OF_SILICA_SAND_FOR_LEACHATE_TREATMENT_2009_MSc_CE_BSB_24.pdf application/pdf en public masters Universiti Sains Malaysia Pusat Pengajian Kejuruteraan Awam
