Journal of Chemical Learning Innovation (Jor. Chem. Lea. Inn) is a double-blind peer-reviewed journal dedicated to disseminating advances in science and research in the field of chemical education both in Indonesia and in the global context of developing countries. Committed to excellence, the Journal of Chemical Learning Innovation publishes comprehensive research articles and invited reviews from leading experts in Chemical Education and fine chemistry. The selection criteria prioritize papers that demonstrate high scientific value, convey new knowledge, and significantly impact chemistry and fine chemistry education. This journal focuses on evaluating, teaching and learning chemistry and related topics at the school and college level.</p> en-US <div> <p style="text-align: justify;">Authors who publish with this journal agree to the following terms:</p> </div> <ol style="text-align: justify;"> <li class="show">Authors retain copyright and acknowledge that the Journal of Chemical Learning Innovation is the first publisher licensed under a <a href="https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 International License</a>.</li> <li class="show">Authors are able to enter into separate, additional contractual arrangements for the non-exclusive distribution of the journal's published version of the work (e.g., post it to an institutional repository or publish it in a book), with an acknowledgment of its initial publication in this journal.</li> <li class="show">Authors are permitted and encouraged to post their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges and earlier and greater citation of published work.</li> </ol> cic.jocli@gmail.com (Fhadira Insani Putri) Fri, 19 Dec 2025 10:03:27 +0700 OJS 3.1.2.4 http://blogs.law.harvard.edu/tech/rss 60 https://cahaya-ic.com/index.php/JoCLI/article/view/2249 <p><strong>Purpose of the study: </strong>The aim of this study is to understand the process of water treatment in each step and to understand the effectiveness of the removal of phosphorus and nitrogen from wastewater.</p> <p><strong>Methodology:</strong> For nitrogen removal must be through many processes such as Nitrogen fixation, or Ammonification, and Denitrification. For the phosphorus. The additional Ferric Chloride in the Aeration tanks to a reaction between the melt and the mud bolts is separated at the Clarifier tank. The Coagulation basin adds Ferric Chloride at 40% concentration of 0.05ml in contaminated water 1000ml for nitrogen and phosphorus concentration tests and studied in the condition the nitrogen can be removed from contaminated water well depending on the pH value and temperature. The removal of phosphorus by adding 0.05ml ferric chloride and 5ml of polymer cation 1040 (powder) can tank up to 80% phosphorus at the temperature of 200C and pH 7.</p> <p><strong>Main Findings: </strong>As a result, the good conditions for nitrification are the pH of between 7.5 and 8.6 at temperature in the tank between 20⁰C and 25⁰C and the denitrification has a pH of between 7.5 and 8 and temperature in the tank from 20⁰C to 35⁰C. Result show that the remaining phosphorus is below the ministry of environment standard set (P &lt;2mg/l).</p> <p><strong>Novelty/Originality of this study: </strong>The next study should observe the amount of polymer to be applied after adding iron and studying the speed of iron chips as it affects the removal of phosphorus.</p> Mardy Serey, Sreypov Chhorn, Chinda Chhe Copyright (c) 2025 Mardy Serey https://creativecommons.org/licenses/by/4.0 https://cahaya-ic.com/index.php/JoCLI/article/view/2249 Fri, 19 Dec 2025 00:00:00 +0700
