Treatment of saline leachate using electrocoagulation process

Treatment of saline leachate using electrocoagulation process / Ain Syazana Zulkafli
Larut lesapan merupakan salah satu air sisa sangat tercemar. Ia mengandungi kepekatan organik yang tinggi, ion tak organik, nitrogen ammonia(NH3-N), bahan pencemar degil (POPs), logam-logam berat serta lain-lain pencemar organic tidak terurai. Walau bagaimanapun, kemasinan larut resapin akan sedikit mempengaruhi proses rawatannya. Untuk mempunyai kecekapan rawatan larut resap, rawatan yang sesuai akan dijalankan untuk mendapatkan penyelesaian menguruskan larut lesapan pada masa akan datang. Oleh itu, bagi kesihatan manusia dan alam sekitar di masa depan, penyelesaian yang tepat harus dilakukan untuk memastikan generasi baru mempunyai lingkungan terbaik untuk berkembang. Selain itu, ekosistem bumi yang perlu dipertimbangkan, ini kerana manusia bergantung kepada sumber-sumber fenomena dan alam semula jadi. Penyelidikan rawatan air sisa ini adalah untuk menentukan kecekapan penyingkiran logam berat (Fe, Zn, Mn, Cu), penyingkiran COD, penyingkiran kekeruhan dan penyingkiran nitrogen ammonia daripada rawatan air sisa beresin dengan menggunakan proses elektrokoagulasi pada masa tertentu. Ia juga mengkaji kesan parameter seperti voltan yang digunakan, masa rawatan yang diperlukan dan pH awal untuk mencapai penyingkiran yang lebih tinggi. Kemudian, untuk memerhatikan kelakuan saiz flok dari proses elektrokoagulasi dalam rawatan larut resin garam. Kaedah penyelidikan ini adalah dengan menggunakan proses elektrokoagulasi. Kaedah ini adalah dengan mengawal pembolehubah proses elektrokoagulasi ini seperti voltan yang digunakan, nilai pH awal dan masa rawatan eksperimen ini. Akibatnya penyingkiran pembolehubah yang lebih tinggi akan menjadi rujukan pada masa depan untuk proses rawatan larut resapan. Oleh itu, peratusan kecekapan penyingkiran logam berat tembaga, mangan, zink dan besi, kekeruhan, COD dan ammoniacal-nitrogen adalah 100%, 97.22%, 90.05%, 90.05%, 95.90%, 55.95% dan 90.84%. Kemudian, untuk saiz zarah flok bergantung kepada voltan dan masa rawatan proses elektrokoagulasi. _______________________________________________________________________________________________________ Landfill leachate is one of the most polluted wastewater. It contains high concentrations of organic matter, inorganic ions and ammonia nitrogen (NH3N), persistent organic pollutants (POPs), heavy metals and other recalcitrant organic pollutants. However, the salinity of the leachate will slightly affect the treatment method. To have an efficient saline leachate treatment, the appropriate treatment will be performed to obtain the solution for the future management of the leachate. Therefore, for the wellbeing of human health and environment in the future, the proper solution must be identified to make sure the new generation had the best surrounding for their growth. Besides, the ecosystem of the earth should be considered by us as a human being as we depend on the resources of the natural. This research aimed to determine the efficiency of heavy metal (Fe, Zn, Mn, Cu) removal, COD removal, turbidity removal and ammoniacal nitrogen removal from saline leachate treatment by using electrocoagulation process at specific time and also to study the effect of parameter such as applied voltage, treatment time required an initial pH to achieve higher removal. Then, it is also aimed to observe the floc size behaviour from the electrocoagulation process in saline leachate treatment. This research was conducted using electrocoagulation process. This method was conducted by controlling the parameter of this electrocoagulation process such as their applied voltage, initial pH value and treatment time of this experiment. As a result, the parameter that achieves the highest removal will become a reference in future for the leachate treatment process. Therefore, the percentage of removal of heavy metal which are copper, manganese, zinc and iron, turbidity, COD and ammoniacal-nitrogen are 100%, 97.22%, 90.05%, 90.05%, 95.90%, 55.95% and 90.84% respectively. Then, for floc particle size, it depends on the voltage and the treatment time of the electrocoagulation process.
