Abstract

Percobaan penyisihan H₂S dan NH₃ menggunakan biofilter dalam skala laboratorium telah dilaksanakan dengan menggunakan dua jenis media (limbah padat karet dan seraut sawit) dan konsorsium mikroorganisme yang melekat secara alami dalam media. Tujuan dari percobaan ini adalah untuk menentukan kinerja biofilter serta evaluasi pengembangan model biofilm, pengendali reaksi dan konveksi-difusi-reaksi (KDR). Hasil pengujian menunjukkan efisiensi penyisihan gas H₂S menggunakan kedua jenis media mencapai 99,5%, dan untuk kontaminan NH₃ mencapai 99% pada media seraut sawit dan bervariasi pada selang 60-98% untuk media limbah padat karet. Dari pengembangan model menunjukkan bahwa profil laju penyisihan kontaminan dapat diprediksi dengan model biofilm dan model pembatas reaksi. Kinetika penyisihan tersebut dikendalikan oleh reaksi biokimia mikroorganisme pada biofilm. Model KDR dinilai cocok untuk memprediksi profil konsentrasi kontaminan sepanjang biofilter.

use for classroom teaching by the Author or the Author's institution and presentation at a meeting or conference and distributing copies to attendees;
use for internal training by the author's company;
distribution to colleagues for their research use;
use in a subsequent compilation of the author's works;
inclusion in a thesis or dissertation;
