KINETIKA FILTRASI LIMBAH CAIR INDUSTRI TAHU DENGAN MENGGUNAKAN METODE BIOFILTER MEDIA ZEOLIT
Abstrak: This research was
aimed to investigate reaction kinetic of tofu industry wastewater using zeolite
medium. A static filter reactor using
zeolite medium was constructed to carry out this research. Tofu wastewater was resirculated through the
medium with various hydraulic retention times (HRT): 0, 3, 6, 12, 24, 36, and
48 hours. First orderreaction was then
applied on this kinetics. The results
showed that pH increased from 4.1 to 8.02.
Total P in the wastewater decreased from 12,1 mg/L to 6,91 mg/L (42%
reduction), while in the media total P increased from 3,04 mg/L to
5,97 mg/L within 48
hours of filtration. N-NH4 +
decreased from 64.184 mg/L
to 12.85 mg/L (79.9% reduction). Total Solids decreased from 10.404 mg/L to
4003 m (61.5% reduction).
