The Simulation and Experimental Study of COD Removal from Rubber Industrial Wastewater using Anaerobic Fixed Bed Reactors
Industrial wastewater from natural rubber factories has a strong odor due to its high organic content of mostly protein compounds. An anaerobic fixed bed reactor (AFBR) can be used in treating rubber wastewater due to the reactor’s ease of operation and short residence time. However, the reactor...

| Summary: | Industrial
wastewater from natural rubber factories has a strong odor due to its high
organic content of mostly protein compounds. An anaerobic fixed bed reactor
(AFBR) can be used in treating rubber wastewater due to the reactor’s ease of
operation and short residence time. However, the reactor's design parameters
need to be modeled and tested for use in a laboratory before it can be used
industrially. This study aims to
examine the effect of immobilization media and the presence of trace element,
Fe(II), in AFBR for the treatment of natural rubber wastewater. The reactor was
operated in two modes: batch and semicontinuous modes. The removal of soluble
chemical oxygen demand (sCOD) and methane production during the process were
monitored, and the kinetics of COD decomposition were simulated. A high
reaction rate constant and high COD removal rate of more than 90% was observed
when the reactor was operated using immobilized media and Fe(II). |
