PEMANFAATAN LUMPUR AKTIF DALAM MEREDUKSI FENOL
Abstract: This study aims to
determine the effect of activated sludge microbes in reducing phenol compounds
contained in industrial wastewater plywood. Given that the plywood industry
uses resin Phenol Formaldehyde (PF) as the main mix adhesive, produces
wastewater containing phenolic compounds that are toxic (poison) to the
environment. The results with 95% confidence level indicates the number of
microbes have a significant influence on phenol reduction of 62.25 mg / L to
4.09 mg / L, with the equation y = -0.606 x + 14.76 and r value of 0.967. Which
means that 96.7% of phenol is affected by microbial reduction. The test results of phenol in
industrial wastewater plywood showed the efficiency of wastewater treatment
process reached 93.43%. On the initial conditions phenol observation (without
treatment), levels of phenols in industrial wastewater plywood for 62.25 mg /
L. Once mixed with activated sludge, a decrease in phenol content as follows:
the 15-minute levels of phenol 9.58 mg / L, at 30 minute levels of phenol 9.25
mg / L, at 60 minute levels of phenol 7.46 mg / L, the 120 min levels of phenol
6.50 mg / L, the phenol content of 240 minutes 6.08 mg / L, the phenol content
of 480 minutes 4.09 mg / L.
Key words: activated sludge,
