ABSTRACT
The pulp and paper industry is a water-intensive industry, and number third in the
world and also a significant contributor to pollutant discharge to the environment.
It is know that the low BOD/COD ratio obtained from pulp industry wastewater is
an average of 0.3 (1/3) while the ideal of biodegradability value is in the range
above 0.5 (1/2). Thus, there are alternative treatments that can degrade hazardous
compounds in wastewater that are slow to degrade through the oxidation process,
known as the Advanced Oxidation Process (AOP). AOP is based on active radicals
which are produced as oxidizing agents to mineralize the complex chemical
substance in the wastewater. One of the active radicals, known sulfate radicals
(SO4*), has a high oxidation potential of 2.5 – 3.1 V. Several studies showed that
radical sulfates can be produced by catalytic oxodation process, such as
combination of Peroxymonosulfate with homogeneous metal ion catalyst (Fe2+,
Mn2+, Ni 2+, Co2+, Cd2+, Cu2+, Ag+1, Cr3+, Zn2+). In this study, AOP method
peroxymonosulfate which was activated with the catalyst α-MnO2-400 were used
to treat organic content in wastewater of pulp and paper industry. The α-MnO2-400
catalyst was produced from 1:3 molar potassium permanganate (KMnO4) and
maleic acid that calcined at 400oC. This catalyst was characterized by XRD, BET
and FESEM. From XRD analysis obtained the peak aligned with JCPDS Standard.
From the BET analysis obtained surface area is 49.17 m2/g, pore size 6.4 nm and
pore total 0,16 cm3/g. From FESEM analysis obtained crystalit structured with
average length 21 nm. The best degradation of COD and TOC concentration
obtained at temperature 45oC, at retention time 240 minutes, with
peroxymonosulfate concentration 2,0 g/L and catalyst concentration 0,4 g/L (73%
and 77%).
