Abstract Aerobic granular sludge (AGS) is known as excellent biological treatment for wastewater industry, high organic load and adsorption of heavy metal. AGS have some advantages such higher density, biomass retention, simultaneous nutrient removal tolerance to toxicity. The aim this research use sequencing batch reactor (SBR) cultivate in the short time (28 days) laboratory scale. Experiment...

a biofilm sequencing batch reactor with a volume of 1.42 m3, nylon nets providing a 4,140 m2/m3 support area for biofilms and an automated operation with 8 hour cycles was studied. the duration of the experiment was 135 days. removal efficiencies e≥ 80% were obtained for carbonaceous matter, producing an effluent with 31±26.8 mg/l of filtered cod, 7±3.6 mg/l of bod5 and 12±3.2 mg/l of toc. the ...
