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...

Abstract Thai cassava starch industry generates solid waste or pulp approximately of 9.5 Mt/y (with a moisture content 70–80%). Biogas production technology has been introduced for several decades in Thailand. However, the implementation biogas using as feedstock is still limited due to complex lignocellulosic structure, which diminishes hydrolysis. This work investigated from 50-m 3 pilot-scal...

In this work autotrophic nitrogen removal was implemented through the combined biological processes of short-cut nitrification and anoxic ammonium oxidation (anammox) in a single sequencing batch reactor (SBR). The SBR received the effluent of an upflow anaerobic sludge blanket (UASB) that treated low strength synthetic wastewater. The main challenge was to develop anammox bacteria that will be...

BACKGROUND The aim of this study is to accelerate and improve aerobic granulation within a Sequencing Batch Reactor (SBR) by cationic polymer addition. METHODS To identify whether the polymer additive is capable of enhancing granule formation, two SBRs (R1 and R2, each 0.15 m in diameter and 2 m in height) are used by feeding synthetic wastewater. The cationic polymer with concentration of 30...

Completely autotrophic nitrogen removal over nitrite (CANON) process was employed in an 18 L sequencing batch reactor (SBR) for treatment of optoelectronic industrial wastewater containing high strength ammonium nitrogen (3712 ± 120 mg NH4(+) - N L(-1)). About 89% of total nitrogen and 98% of NH4(+) - N removal efficiencies were observed at the loading rate of 909 g N m(-3) d(-1) and the HRT of...

background: among alkanes, n-alkanes with medium chain have been identified as the most important contaminants of the soil. n-hexadecane (c16h34) with low solubility in water also belongs to this group and has been used by many researchers as a model contaminant. the present study aimed to investigate the effect of the external source of carbon (glucose) as co-substrate on removal of hexadecane...

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...
