Determination of bod kinetics coefficient (k1) for the leachate less than 5 years from Pulau Burong landfills

Determination of bod kinetics coefficient (k1) for the leachate less than 5 years from Pulau Burong landfills / Zulaikha Kamaludin
Nilai Pekali kinetik BOD (k1) dan nilai BOD muktamad(L0)merupakan parameter utama dalam olahan air sisa termasuklah larut lesapan. Kedua- dua nilai ini amat diperlukan dan berguna untuk mereka bentuk sistem tangki pengudaraan enap cemar teraktif, tangki pengoksidan dan lain- lain. Pada masa sekarang, nilai tersebut belum lagi ada untuk larut lesapan. Terdapat beberapa kaedah untuk menentukan nilai pekali kinetik k1 dan nilai BOD muktamad, L0. Kaedah tersebut seperti “Least-square technique”, “Slope method”, “Moment method”, “Logarithmic method” dan “Rhame`s method”. Objektif kajian ini dijalankan adalah untuk mencari nilai k1 dan L0 untuk larut lesapan dari tapak pelupusan sampah Pulau Burong. Nilai ini amat diperlukan untuk membina sistem rawatan larut lesapan yang lebih kurang sama di Malaysia dan juga di luar negara. Keputusan dari pengiraan yang dibuat, nilai untuk k1 dan L0 adalah dalam lingkungan 0.02349-0.1205 per hari (Purata = 0.0718 per hari )dan 355.389-747 mg/L untuk kolam A dan nilai Lo adalah dalam lingkungan 355.389 -747 mg/L (Purata = 495 mg/L).Untuk kolam B, nilai k1 dan L0 adalah dalam lingkungan 0.0236 -0.110 per hari (Purata = 0.0743 perhari) dan L0 329.27-707 mg/L (Purata = 545 mg/L). Daripada keputusan ini, didapati “Slope method” memberikan nilai k1 yang terkecil sekali dan nilai Lo yang terbesar sekali bagi kedua- dua kolam. Manakala “Logarithmic method” menghasilkan nilai k1 yang terbesar bagi kedua- dua kolam tersebut. _______________________________________________________________________________________________________ Rate of BOD degradation (k1) and the ultimate BOD (L0) are among the main parameters in biological treatment of wastewater, including leachate. These values are used for the design of aeration tank in activated sludge system, oxidation pond etc. Currently these values are not available for leachate. There are a few methods commonly used to determine k1 and Lo. These includes Least-square technique, Slope method, Moment method, Logarithmic method and Rhame`s method. The objectives of this study is to determine the rate constant, k1 and ultimate BOD, L0 values for semi aerobic leachate at Pulau Burong landfills. These values are very important and useful in the future for design leachate treatment plant with similar characteristic in Malaysia and overseas. Results indicated that the k1 values were in the range of 0.02349 day-1 to 0.1205 day-1 (Average = 0.0718 day-1) and L0 values 355.389 to 747 mg/L (Average = 495 mg/L) for Pond A. For pond B, the k1 values were in the range of 0.0236 to 0.110 day-1 (Average = 0.0743 day-1) and L0 329.27 to 707 mg/L (Average = 545 mg/L) respectively. Results indicated that for both ponds, the Slope method produced the lowest k1 value but the highest L0 value. In comparison, the Logarithmic method produced the highest k1 values for both ponds.
