Proses Adsorpsi-Degradasi Limbah Cair Pabrik Kelapa Sawit Menggunakan Adsorben Bentonit Dan Komposit Mno2/Bentonit

---

The high level of organic contaminants and total solid contained in Palm Oil Mill
Effluent (POME) were reflected in its high values of COD, TSS and TDS,
requiring a proper treatment prior to discharge into an environment. The
adsorption-degradation processes were used to treat POME using bentonite as the
adsorbent and MnO2/bentonite composite as the heterogenous Fenton catalyst.
According to diffractograms obtained from XRD analysis, montmorillonite was
found as the main phase of bentonite along with other minor phases such as
feldspar, quartz, and cristobalite, whereas the manganese oxide was a typical
porous cryptomelane-type manganese oxide. Following the formation of
composite, the majority of XRD peaks are due to bentonite with minor peaks of
cryptomelane. The BET analysis indicated that MnO2/bentonite possessed smaller
surface area in comparison to bentonite and cryptomelane. The maximum
adsorption of POME was attained by monitoring the highest COD removal, which
is 90,67% achieved after 45 minutes of adsorption by 500 mg/L bentonite. The
degradation process was then conducted to the pre-treated remaining POME.
Based on this investigation, MnO2/bentonite 15% and H2O2 3400 mg/L showed
the best performance for the degradation of POME by reducing COD and TSS to
310,68 ppm and 248 ppm after 240 minutes of degradation, both already met the
quality standard. On the other hand, there was no significant change in TDS and
pH of the observed POME after the treatment was carried out.
