ABSTRACT
The present study investigated the efficiency of aerobic granular
sludge (AGS)
technology in treating effluent from soy sauce industry which is categorized as
a high strength wastewater. The combination of anaerobic and aerobic
granulation technology in SBR system was used in this study which was
efficiently treated COD from the soy sauce wastewater where 87% of
removal was achieved. Ammonia and colour was removed at a maximum of 87 and
76%, respectively, in the SBR system. Matured, dense and compact
granules with 2.5 mm in diameters were developed with a good settling velocity
(45 m/h) and 28 mL/gSS of sludge volume index (SVI). Hence, AGS technology
was proven as an excellent treatment for soy sauce wastewater for being
discharge into the environment, as the effluent was treated in one biological
reactor with high hydraulic and organic loadings besides less production of sludge.
In this study, the capabilities of AGS technology in treating relatively higher
concentration of organic impurities present in the soy sauce wastewater were
demonstrated.

ABSTRAK
Penyelidikan ini mengkaji kecekapan enapcemar
teknologi granul aerobik (AGS) dalam merawat efluen daripada industri
kicap yang dikategorikan sebagai air sisa yang berkuatan tinggi. Gabungan teknologi granul anaerobik dan aerobik
di dalam sistem SBR telah digunakan dalam kajian ini dengan COD daripada air sisa
kicap telah dirawat dengan cekap dengan 87% penyingkiran telah dicapai. Ammonia
dan warna telah dirawat dengan peratusan penyingkiran yang maksimum
masing-masing adalah 87 dan 76% dalam sistem SBR ini. Granul yang
matang, padat dan mampat telah terbentuk serta mempunyai 2.5 mm diameter dan
halaju enapan yang baik (45 m/h) dengan 28 mL/gSS indeks isi padu enapcemar (SVI).
Oleh itu, teknologi AGS telah dibuktikan sebagai satu teknologi
rawatan yang sangat bagus bagi air sisa kicap untuk dilepaskan ke alam sekitar,
tambahan pula efluen air sisa kicap tersebut telah dirawat di dalam reaktor
biologi yang berupaya menanggung beban hidraulik dan organik yang tinggi di
samping mengurangkan pengeluaran enapcemar. Dalam kajian ini, keupayaan
teknologi AGS dalam merawat kepekatan bendasing organik yang tinggi yang
terdapat dalam air sisa kicap ini telah ditunjukkan.
