ABSTRACT A new biomass productivity model was parameterized for Chlorella vulgaris using short‐term (<30 min) oxygen productivities from algal microcosms exposed to 6 light intensities (20–420 W/m 2 ) and temperatures (5–42°C). The then validated against experimental recorded in bench‐scale photobioreactors operated under 4 (30.6–74.3W/m (10–30°C), yielding an accuracy of ± 15% over 163 days cultivation. This modeling approach addresses major challenges associated with the accurate...
Large-scale microalgae cultivation for biofuel production is currently limited by the possibility of maintaining high yield and lipid content, concomitantly. In this study, physiological changes Chlorella vulgaris NIES 227 during accumulation under nutrient limitation was monitored in parallel with photosynthetic capacity to fix carbon from proxy oxygen productivity. exponential growth phase, as biomass composition did not vary significantly (approx. 53.6 ± 7.8% protein, 6.64 3.73% total...
Abstract Escherichia coli (E. coli) first-order decay rates ranging from 3.34 to 11.9 d−1 (25–75% data range, N = 128) were recorded in two outdoor pilot-scale (0.88 m3) high rate algal ponds (HRAPs) continuously fed primary domestic wastewater over years (influent E. cell count of 4.74·106 ± 3.37·106 MPN·100 mL−1, 142). The resulting removal performance was relatively constant throughout the year (log10-removal averaging 1.77 0.54, 128), apart a significant drop during cold rainy period....
Abstract While there is growing evidence that High Rate Algal Ponds (HRAPS) can support disinfection during wastewater treatment, the mechanisms of pathogen removal involved remain unclear. Based on previous findings, present study aimed at verifying occurrence and significance dark decay, alkaline-pH toxicity, sunlight direct damage in conditions representative ‘real’ HRAP operation. For this purpose, Escherichia coli cell count was monitored hourly 24 h periods outdoor pilot HRAPs fed...
While high rate algal ponds (HRAPs) can provide efficient pathogen removal from wastewater, the mechanisms involved remain unclear. To address this knowledge gap, potentially causing Escherichia coli (E. coli) during microalgae-based wastewater treatment were successively assessed using laboratory microcosms designed to isolate known mechanisms, and bench scale assays performed in real HRAP broth. During assays, E. decay was only significantly increased by alkaline pH (above...
The constantly growing demand for energy and the concern about security environment motivates production of fuels chemicals from different sustainable raw materials. Microalgae are considered producing third-generation biofuels due to their capacity grow rapidly potential CO2 fixation. In this context, continuous hydrothermal liquefaction (HTL) carbohydrate-rich microalga, Chlorella sorokiniana (CS) NIES 2273, lipid-rich vulgaris (CV) 227, was performed. Then, bio-oil hydrotreated (HDT) over...
