Abstract
The increasing concentration of ammonium in domestic wastewater is one of the main contributors to water pollution, potentially leading to eutrophication. This study aims to remove ammonium from domestic wastewater using synthetic zeolite 13X as an adsorbent. The zeolite was characterized using SEM and XRD tests to identify its morphological structure and phase composition. Adsorption kinetics were studied using the Lagergren’s First Order, Pseudo Second Order, Elovich, and Intraparticle models, with the Elovich model showing the best fit (SSE = 0.08693). Meanwhile, the adsorption isotherm study indicated that the Langmuir-Vageler model was the most appropriate (SSE = 0.0006), indicating significant interaction between ammonium and the zeolite surface. Increasing the mass of zeolite improved ammonium removal efficiency, although efficiency tended to plateau once the system reached saturation. The effect of initial solution concentration on removal efficiency showed that the highest efficiency was achieved at an initial concentration of 20 ppm. On the other hand, pH variation had no significant effect on adsorption performance. These findings suggest that synthetic zeolite 13X has effective adsorption capabilities under certain conditions. Overall, zeolite 13X has proven to be effective for use in domestic wastewater treatment to reduce ammonium content.

| Additional Information: | Peningkatan kadar amonium dalam limbah domestik menjadi salah satu faktor utama pencemaran perairan yang dapat menyebabkan eutrofikasi. Penelitian ini bertujuan untuk menyisihkan amonium dari limbah domestik menggunakan zeolit sintetik 13X sebagai adsorben. Karakterisasi zeolit dilakukan melalui uji SEM dan XRD untuk mengidentifikasi struktur morfologi dan fase zeolit. Studi kinetika adsorpsi dilakukan menggunakan model Lagergren’s First Order, Pseudo Second Order, Elovich, dan Intraparticle, dengan hasil terbaik ditunjukkan oleh model Elovich (SSE = 0,08693). Sedangkan studi isoterm adsorpsi menunjukkan model Langmuir-Vageler sebagai model paling sesuai (SSE = 0,0006), menandakan terjadinya interaksi yang signifikan antara amonium dan permukaan zeolit. Peningkatan massa zeolit meningkatkan efisiensi penyisihan amonium, namun efisiensi cenderung stagnan setelah sistem mencapai kondisi jenuh. Pengaruh konsentrasi awal larutan terhadap efisiensi penyisihan menunjukkan bahwa efisiensi tertinggi dicapai pada konsentrasi awal 20 ppm. Sedangkan variasi pH tidak memberikan pengaruh signifikan terhadap kinerja adsorpsi. Hal ini menunjukkan bahwa zeolit sintetik 13X memiliki kemampuan adsorpsi yang efektif dalam kondisi tertentu. Secara keseluruhan, zeolit 13X terbukti efektif untuk digunakan dalam pengolahan limbah domestik dalam upaya mengurangi kandungan amonium. | ||||||
