Increasing energy demands and greenhouse gases emission from wastewater treatment processes prompted the investigation of alternatives capable to achieve effective treatment, materials recovery, reduce environmental footprint. Combination microbial fuel cell (MFC) technology with microalgal-based process in MFC-PBR (photobioreactor) systems could emissions facilities, capturing CO2 emitted indu...

An alternative way to remove CO2 from biogas is the use of photosynthetic microorganisms, such as microalgae. This can be achieved by operation an open photobioreactor, connected with a mass transfer column, counterflow column. technology provides up-graded high quality. The microalgal uptake in columns generates pH changes microalgae culture. To clarify potential effect these dynamic condition...

Studies attempting to optimise photosynthetic biogas upgrading by simultaneous investigation of the bubble column-photobioreactor setup have experienced considerable variability in results and conclusions. To identify sources such variation, this work quantitatively compared seven design factors (superficial gas velocity; liquid flow rate (L/G) ratio; empty bed residence time; inlet pH; alkalin...

The Arabian Peninsula’s advantageous climate, availability of non-arable land, access to seawater and CO2-rich flue gas, make it an attractive location for microalgae biomass production. Despite these promising aspects, the region has seen very few studies into commercial feasibility algae-based value chains. This work aims address this gap through a techno-economic study algae production costs...

Sugar-mill wastewaters have potential to support microalgal biomass production for use as a biofuel feedstock (lipid source). Growth kinetics, light dynamics, and lipid production in multispecies-microalgae cultures collected from a sugar-mill pond are reported in this paper. Lipid content of the microalgae collected from the pond water was 14.5 % (w/w). Culturing the same microalgae in a photo...

A versatile LED based miniature photobioreactor ideal for factorial experiments that allows simultaneous testing of a wide range variables and experimental combinations needed high-throughput screening analysis.

Photoautotrophic microalgae offer high promise for a tertiary treatment of livestock wastewater owing to their rapid growth and nutrient uptake. To screen better microalga for the tertiary treatment, batch photobioreactor tests were conducted using Chlorella emersonii, Chlorella sorokiniana, and Botryococcus braunii. This study evaluated their specific growth rates, CO2 utilization rates, and n...
