Anika Tiong, Yong Bin creator author. text my 2025 2025 monographic eng xv, 40 pages : illustrations ; Ammonia which usually presents as ammonium ion (NH₄⁺) contaminates ecosystems and also harms human health. The research focused on the ammonium removal from industrial wastewater using mixed culture. The wastewater sample containing ammonia from TAF Agriculture Trading & Services in Melaka was preliminarily treated using a mixed culture. The inoculum sizes were varied at 5%, 10%, and 15% (v/v), and the samples were taken every 24 for 96-h treatment. When the inoculum size was increased, the remaining ammonium concentration decreased. The ammonium concentration reduced from 118 to 35 mg/L (70.3% reduction) at 96 h treatment using 15% (v/v) inoculum size. The results show that ammonia in the wastewater could be reduced using the mixed culture. specialized Anika Tiong Yong Bin Faculty of Chemical and Process Engineering Technology Final Year Report (Bachelor of Chemical Engineering ) -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2025 Include bibliographical reference Faculty of Chemical and Process Engineering Technology Dissertations Universities and colleges Dissertations Theses Dissertations THE0010662 (Local) https://umpir.ump.edu.my/id/eprint/47443 https://umpir.ump.edu.my/id/eprint/47443 UMPSA 260703 20260707150937.0 eng
