The Efficiency of Air-lift Bioreactor Using PVA-gel Carrier Materials to Treat Organic Components in Artificial Wastewater
Main Article Content
Abstract
An air-lift bioreactor using PVA-gel was used to remove organic components in wastewater treatment. The wastewater treatment system using Sequencing Batch Reactor with carrier material volume of 5%, activated sludge density of 2.5 g/L to treat artificial wastewater made from cat food (Whiskas) with initial COD content of 2,000 mg/L. After 10 days of operation, the removal efficiency of total COD, soluble COD, and achieved 92, 89, and 84%, respectively. Despite the high removal efficiencies of organic components, the output wastewater did not achieve QCVN 40:2011/BTNMT (Column B) discharge standards. Due to high concentrations of TSS and slow biodegradable organic components. The experimental system will be necessary to study the operating conditions to treat wastewater more efficiently and achieve the discharge standards to
the environment.
Keywords:
Air-lift bioreactor, artificial wastewater, PVA-gel, organic component, removal efficiency.
