Abstract:
... In this study, the effects of liquid digestate pretreatment of wheat straw on its biogas production efficiency and anaerobic digestion were investigated using a laboratory-scale biochemical methane potential test. Scanning electron microscope, X-ray diffraction analysis and Fourier transform infrared spectroscopy were used to analyze the changes in main compositions and physico-chemical structure ...

Pseudomonas fluorescens; ammonium nitrogen; carbon; carbon nitrogen ratio; chemical oxygen demand; constructed wetlands; denitrification; denitrifying bacteria; granules; nitrate nitrogen; nitrogen; pH; rice hulls; subsurface flow; total nitrogen; wastewater
Abstract:
... The denitrification process for treating low carbon/nitrogen (C/N) wastewater in horizontal subsurface flow constructed wetlands (CWs) is often restricted by the carbon source and both abundance and activity of denitrifying bacteria. In this study, the effects of rice husks or immobilized Pseudomonas fluorescens on N removal were investigated under various conditions in a synthetic wastewater solu ...

Subject:
aluminum oxide; ammonium nitrogen; biofilm; chemical oxygen demand; denitrifying bacteria; municipal wastewater; nitrifying bacteria; nitrogen; nutrients; phosphorus; shale; wastewater treatment; wetlands
Abstract:
... A tidal flow constructed wetland (TFCW), a commonly applied system to clean wastewater, contains a substrate to assist pollutants removal, while the choice of substrate affects the formation of bacterial biofilms. Herein, activated alumina-TFCW (A-TFCW) with hydraulic load of 1.35 m³/(m²·d) parallel with shale ceramisite (S-TFCW) was investigated for treating domestic wastewater, aiming to enhance ...

Subject:
ammonium nitrogen; anaerobic digestion; biomass production; community structure; effluents; fatty acid composition; inoculum; lipid metabolism; lipids; microalgae; microbial communities; mixed culture; nitrogen; sludge; starvation
Abstract:
... This study examines the potential of the mixed-culture microalgal consortia enriched from aerobic sludge (AeS) and anaerobic sludge (AnS) with regard to nutrient removal and biomass production from four different anaerobic digestion (AD) effluents. Both the inocula achieved the complete removal of the NH₄⁺-N (initial concentration of 40 mg/L) within 14 days from all the effluents. The AeS cultures ...

Abstract:
... The aim of this study was to assess the effect of primary treatment on the performance of two pilot-scale high rate algal ponds (HRAPs) treating urban wastewater, considering their treatment efficiency, biomass productivity, characteristics and biogas production potential. Results indicated that the primary treatment did not significantly affect the wastewater treatment efficiency (NH₄⁺-N removal ...
