The influence of biogas flow rate (0, 0.3, 0.6, and 1.2 m3 m–2 h–1) on the elemental macromolecular composition algal-bacterial biomass produced from upgrading in a 180 L photobioreactor interconnected to 2.5 external bubbled absorption column was investigated using diluted anaerobically digested vinasse as cultivation medium. liquid recirculation/biogas ratio (0.5 < L/G 67) removal CO2 H2S, concentrations O2 N2 upgraded biogas, also evaluated. A 10 considered optimum support H2S removals...
Diatoms, a kind of algae microorganisms with several species, are quite useful for water quality determination, one the hottest topics in applied biology nowadays. At same time, deep learning and convolutional neural networks (CNN) becoming an extensively used technique image classification variety problems. This paper approaches diatom this technique, order to demonstrate whether it is suitable solving problem. An extensive dataset was specifically collected (80 types, 100 samples/type)...
The yearly variations of the quality upgraded biogas and efficiency digestate treatment were evaluated in an outdoors pilot scale high rate algal pond (HRAP) interconnected to external absorption column (AC) via a conical settler. CO2 concentrations ranged from 0.7% August 11.9% December, while complete H2S removal was achieved regardless operational month. CH4 85.2% December 97.9% June, with limited O2 N2 stripping mediated by low recycling liquid/biogas ratio AC. Biomass productivity 0.0 g...
During a survey of freshwater diatoms from Mojiang River, Chebaling Nature Preserve in Shaoguan City, Shixing County, Guangdong Province, China, new Encyonema species, chebalingense sp. nov., was discovered. Based on observations with light and scanning electron microscopy, detailed morphological description E. is here presented. The main features include: conspicuously asymmetrical dorsiventral, semielliptical to semielliptical–lanceolate valves, filiform raphe; dorsal margin clearly arched...
Abstract Diatoms are commonly used in environmental assessments to detect pollution and eutrophication. The specific sensitivity index (SPI) is one of the most frequently indices, which assigns scores diatom taxa based on their pollution. study analyzed communities Duero River basin Spain examine relationship between SPI various limnological variables. A GLM model showed that phosphates, nitrites, water temperature were main factors explaining variability. also reviews previous results using...
This paper deals with automatic taxa identification based on machine learning methods. The aim is therefore to automatically classify diatoms, in terms of pattern recognition terminology. Diatoms are a kind algae microorganism high biodiversity at the species level, which useful for water quality assessment. most relevant features diatom description and classification have been selected using an extensive dataset 80 minimum 100 samples/taxon augmented 300 samples/taxon. In addition published...
This work aimed at integrating the anaerobic digestion of food waste (FW) with photosynthetic biogas upgrading pilot scale in order to obtain a high quality biomethane and nutrient-laden algal biomass as main byproducts from FW treatment. The performance 100 L digester treating integrated via raw digestate injection 1.2 m2 outdoors high-rate pond (HRAP) was evaluated. Biogas production averaged 790 ± 89 mL g VSin-1 (68 8 d-1) (35 °C, 1 bar) loading rate 0.86 VS L-1 d-1 steady state chemical...
Anaerobic digestion can biotransform the biodegradable fraction of sewage sludge into biogas, while symbiotic action algal-bacterial consortia remove both CO2 and H2S from biogas nutrients digestate. A 100 L anaerobic digester operated at 20 days retention time coupled with a 180 high-rate algal pond (HRAP) engineered to upgrade treat liquid pilot was optimized along four operational stages: (I) operation greenhouse during winter; (II) without greenhouse; (III) process supplementation...
