Abstract

In this study, the management of domestic wastewater from the regional hospital of Ogan ilir
district was carried out by combining adsorption methods using palm fiber activated charcoal
adsorbent and filtration using nanofiltration (NF) membranes. The palm fiber activated charcoal
adsorbent was produced through a combustion process at 100 ºC for ±24 hours which resulted
in a moisture content and ash content of 1.179 and 4.012 %, respectively. Palm fiber charcoal
was activated using sulfuric acid (H2SO4) and then analyzed using Scanning Electron
Microscope-Energy Dispersive X-Ray (SEM-EDX). The hospital domestic waste treatment
process was carried out with variations in operating time of 20, 40, 60, 80, 100 minutes and
flow rates of 2 and 3 L/min which were then analyzed for ammonia levels before and after the
management process.
