The influence of the liquid-to-biogas ratio (L/G) and alkalinity on methane quality was evaluated in a 11.7 m3 outdoors horizontal semi-closed tubular photobioreactor interconnected to 45-L absorption column (AC). CO2 concentrations upgraded ranged from <0.1 9.6% at L/G 2.0 0.5, respectively, with maximum CH4 89.7% 1.0. Moreover, an enhanced removal (mediating decrease concentration 9.6 1.2%) therefore higher contents (increasing 88.0 93.2%) were observed when increasing AC cultivation broth...
Microalgae-based wastewater treatment plants are low-cost alternatives for recovering nutrients from contaminated effluents through microalgal biomass, which may be subsequently processed into valuable bioproducts and bioenergy. Anaerobic digestion biogas biomethane production is the most straightforward applicable technology bioenergy recovery. However, pretreatment techniques needed to enhance anaerobic biodegradability of microalgae. To date, very few full-scale systems have been put...
The management and disposal of wastewater treatment sludge can be a costly resource-intensive process. To provide cost-effective sustainable alternative, Sludge Treatment Wetlands (STW) have emerged as viable solution for enhancing quality through dewatering biodegradation. In this study, the effectiveness full-scale STW stabilizing digested microalgal biomass from domestic agricultural system was evaluated. properties treated digestate in were assessed after 35 weeks operation resting...
This study gathers the results of operation and optimization thickening microalgal biomass produced at demonstrative scale in photobioreactors fed with agricultural runoff domestic wastewater. The was conducted during two months. system consisted gravity thickeners connected series a multi-stage approach. objective to concentrate microalgae grown (total solids (TS) concentration 0.1–1 g/L) into 20 g/L TS, which considered optimal for subsequent anaerobic digestion process. First, utilization...
High rate algal ponds (HRAP) are known for their suitability to treat wastewater and produce microalgal biomass, which can be converted into bioproducts. However, full-scale application of HRAP is still limited few cases, design procedures not consolidated or standardized. In this study, a demonstrative-scale system secondary treatment implemented in India (treatment capacity 50 m
The objective of this paper is to present the design, construction and operation 3 full scale semi-closed, horizontal tubular photobioreactors (PBR) used remove nutrients a mixture agricultural run-off (90%) treated domestic wastewater (10%). microalgal biomass produced in PBRs was harvested static lamella settling tank. Each PBR average 2.3 m3/d. were submitted strong seasonal changes regarding solar radiation temperature, which had direct impact activity microalgae efficiency system....
