  • In this paper, an electrocoagulation reactor was set up to investigate the ammonium removal in Nam Son landfill leachate. The research focused on studying several factors that affect to the ammonium removal namely current intensity, operating time, initial pH and electrode materials. Mono-polar electrocoagulation reactor was conducted in a batch system with iron electrodes and 1.8 L leachate. The research indicated that current intensity and operating time are directly proportional with NH4+ treatment performance. When applied current increased from 1 to 4A, the NH4+ removal percentage went up from 14.03 to 24.99% after a 1 hour treatment. The effect of initial pH in range of 5 to 10 ...

  • This study attempts to present what the authors have experienced and applied in fostering learner autonomy in Country Studies (namely British and American Studies) at Faculty of English, Hanoi National University of Education. Starting with some main definitions about learner autonomy and its conditions, and basing on authors’ own experience and belief, the authors discuss four main strategies used in teaching and learning Country Studies. The first is designing an appropriate syllabus to help the learners acquire a very clear overview about the main content of the subject, the objectives, the requirements, the evaluation of the program, and the references which all later encourage th...

  • In this study, primarily treating waste sludge rich of Cr, Ni, Fe,…generated from electroplating wastewater treatment plant and experimentally methods of utilizing wastes as inorganic pigment in production of bricks were carried out. Economic, technical and environmental efficiency and feasibility, bases to apply to practical conditions were evaluated. The results show that water accounts for about 70% of sludge. Contents of Ni, Cr and Fe are relatively high (20, 4.5 and 2.5%, respectively). The wastes could be used to replace inorganic pigment in brick production after being primarily treated with a simple procedure. The optimal rate of replacing inorganic pigment is about 5% and ...
