Degradasi Limbah Cair Pabrik Kelapa Sawit Oleh Katalis Mno2 Menggunakan Tahap Pre-Treatment Dengan Adsorben Fly Ash Teraktivasi Hcl

Palm oil mill effluent (POME) has been considered as severe pollutant as it
contains considerable amount of organic materials, has pungent odor, borown in
colour, and low pH. This contaminant must be treated provely in order to fulfill
the national government regulation. The biological treatment process is commonly
used in a palm oil plant using a pond treatment system, but it is time-consuming
(long hydraulic retention time) and requires a large area of land. The advanced
oxidation process (AOP) using Fenton reaction has been reported as an effective
method for degradation of most organic contaminats. In this research, the
adsorption-degradation process had been used to treat the POME obtained from
local palm oil plant. The POME was first treated with adsorption process using
activated fly ash from palm shell ash. The ash was activated by HCl solution and
heated at temperature of 105 oC for 24 hours. The adsorption process was studied
at the different time, different POME concentration, and different concentration of
the ash. Following the adsorption process, the POME was degradated using the
MnO2 catalysts and hydrogen peroxide (H2O2). The performance of MnO2
catalysts increases in the order birnessite CA > birnessite OA > cryptomelane Cu
10% > cryptomelane Co 5%. The H2O2 concentration plays a key role in the
degradation process, too high or low concentrations of H2O2 have negative effect
on the POME degradation. The maximum degradation of POME was achieved
using POME concentration 10:90, 400 mg/L birnessite-CA catalyst and H2O2
concentration of 3,400 mg/L within 150 minutes. This condition was able to
decrease the values of COD, TDS and TSS of 91.67%, 48.11% and 93.93%,
respectively
