Outdoor production of Scenedesmus sp. in thin-layer and raceway reactors using centrate from anaerobic digestion as the sole nutrient source

Wastewater treatment using microalgae: how realistic a contribution might it be to significant urban wastewater treatment?

“…A recently performed in-depth analysis on microalgae based on wastewater composition confirmed these figures (Fouilland et al, 2014). Surprisingly, the cultures are generally dominated by a single strain, making up to 90% of the total microalgae population, although more complex populations can also be found (Morales-Amaral et al, 2015a;Park et al, 2011;Posadas et al, 2014).…”

“…The main contaminants found in wastewater include organic matter (COD), nitrogen and phosphorus, as well as iron and manganese, etc., all of which are required to produce microalgae (Morales-Amaral et al, 2015a). Additionally, other pollutants such as heavy metals and emerging compounds (cosmetics, pharmaceuticals, surfactants, etc.)…”

“…Wastewater can be used to produce microalgae and, at the same time, be cleaned by it; this is because the wastewater's composition is quite similar to the culture media usually utilized to produce Consequently, wastewater contains carbon, nitrogen, phosphorus and other minor components required for microalgal growth although some other undesirable compounds such as heavy metals and emerging pollutants can also be found (Morales-Amaral et al, 2015a;. The utilization of microalgae for wastewater treatment was first reported by Oswald in 1960 but has recently been reviewed (Mehrabadi et al, 2015;Olguín et al, 2012;Park and Craggs, 2010).…”

Recovery of Protein Concentrates From Microalgal Biomass Grown in Manure for Fish Feed and Valorization of the By-Products Through Anaerobic Digestion

“…Biomass was cultured outdoors using a thin layer photobioreactor with a total working volume of 1,200 L, and a surface of 33 m 2 (del Mar Morales-Amaral et al, 2015). The photobioreactor was fed with 10% diluted centrifuged PM at a hydraulic retention time of 0.3 days.…”

Growth modeling of the green microalga Scenedesmus obliquus in a hybrid photobioreactor as a practical tool to understand both physical and biochemical phenomena in play during algae cultivation

“…In this type of system, turbulence is created by gravity such that the suspension culture flows on a ramp. This allows the culture to be grown in very thin layers (averaging 1.0-5.0 cm in height), optimizing the use of light owing to its high surface-to-volume (S/V) ratio (Masojídek & Prasil, 2010; Morales-Amaral, Gómes Serrano, Acién, Fernández-Sevilla, & Molina Grima, 2015).…”
