Performance of composite adsorbent in river water treatment

Performance of composite adsorbent in river water treatment / Izzul Akmal Teruna
Kajian ini dijalankan untuk menilai potensi media komposit yang terdiri daripada karbon aktif, batu kapur dan alginat sebagai pengikat dengan dua nisbah yang berbeza, bertujuan menyingkirkan pencemaran organik dan bukan org-anik yang diukur melalui kepekatan kekeruhan, warna dan Permintaan Oksigen Secara Kimia (COD) di dalam air sungai. Dalam kajian ini, sebelum penjerap komposit diuji, ciri-ciri pencemaran air sungai di Lubok Buntar telah diambil. Walau bagaimanapun, ciri-ciri air air sungai menunjukkan purata kepekatan COD yang rendah. Oleh itu, COD tidak diuji dalam eksperimen kumpulan. Daripada keputusan kajian kumpulan dan graf, faktor yang sesuai adalah 7g dos penjerap komposit, 180 RPM kelajuan goncangan, 75 minit masa sentuhan dan 90 minit masa pengenapan untuk nisbah 7: 3: 2 (AC: LS: AG). Sementara itu, bagi nisbah 1: 9: 2 (AC: LS: AG), faktor yang sesuai adalah 5g dos penjerap komposit, 180 RPM kelajuan goncangan, 95 minit masa sentuhan dan 40 minit masa pengenapan. Dari eksperimen kedua batching, bagi Nisbah 7: 3: 2, penyingkiran peratusan parameter adalah 92% untuk warna dan 85% untuk kekeruhan. Sementara itu, bagi Nisbah 1: 9: 2, penyingkiran peratusan parameter adalah 84% untuk warna dan 60% untuk kekeruhan. Ini menunjukkan bahawa 7: 3: 2 telah dipilih sebagai nisbah terbaik bagi penjerap komposit yang terdiri daripada karbon aktif, batu kapur dan alginat. Sementara itu, untuk setiap parameter, hasil daripada analisis model isoterm menunjukkan kesesuaian proses penjerapan dengan Isoterm Freundlich yang paling munasabah dengan hasil pekali yang tinggi untuk nilai penentuan pada ratio 7:3:2, manakala Isoterm Langmuir adalah sepadan untuk proses penjerapan pada ratio 1:9:2. Untuk kinetik penjerapan, bagi setiap parameter dan kedua-dua nisbah, kadar tindak balas jerapan dikawal oleh mekanisme kedua. _______________________________________________________________________________________________________ This study was carried out in order to access the potential of composite media by a combination of activated carbon, limestone, alginate as a binder with two different ratio, to remove organic and inorganic pollution that measured by concentration of turbidity, colour and Chemical Oxygen Demand (COD) in river water. In this present study, the batching experiment were conducted to decide the suitable factor for both ratio to effectively remove the involved parameter. Before the batching experiments, water characteristics were taken and COD were dismiss from batching experiment due to its low concentration. From the batch study, result and graph indicates that the suitable factor were 7g of dosage, 180 RPM of shaking speed, 75 minutes of contact and 90 minutes of settling time for ratio 7:3:2 (AC: LS: AG). Meanwhile for ratio 1:9:2 (AC: LS: AG), the suitable factor were 5g of dosage, 180 RPM of shaking speed, 95 minutes of contact time and 40 minutes of settling time. From the second batching experiments, for Ratio 7:3:2, the percentage removal of parameters were 92% for colour and 85% for turbidity. Meanwhile for Ratio 1:9:2, the percentage removal of parameters were 84% for colour and 60% for turbidity. This shows that 7:3:2 has been selected as the best ratio for composite adsorbent that consists of activated carbon, limestone and alginate. Meanwhile, the result from isotherms models for each of the parameters removal suggested that Freundlich isotherm was favourable with high coefficient of determination values for ratio 7:3:2 whereas the Langmuir isotherm were fit for adsorption process by ratio 7:3:2. For kinetic of adsorption, for each of the parameters removal by both ratios, pseudo-second-order model was suitable to describe kinetic of adsorption.
