“…Another area in which spectral conversion has had a role in agriculture is the growth of algae. [ 35 ] There are two main locales for algae growth: large, outdoor raceways and more flask based, interior facilities. LSCs could be very useful in raceway algae production as they work in diffuse light, are relatively inexpensive with no sun tracking needed, with the side effect of generating electricity.…”

The luminescent solar concentrator (LSC), originally introduced almost four decades ago as a potential alternative/complement to silicon solar cells, has since evolved to a versatile photovoltaic (PV) solution with realistic potential for seamless integration into the urban architectural landscape. Yet, a popular perception of the device still persists: the LSC is mostly seen as just a low‐efficiency solar panel. This review challenges this outdated notion and argues that the LSC is, to the contrary, a powerful and highly adaptive photonic platform with many more capabilities and potential than only generating electricity from sunlight. The field has seen a rapidly expanding application portfolio over the last few years, with LSCs now considered in various sensing applications, “smart” windows, chemical reactors, horticulture, and even in optical communication and real‐time responsive systems. The main goal of this work is to shed light onto this alternative application space and highlight the LSC's unique spectral manipulation, light distribution, and light concentration properties, and as a result, to encourage the participation from a broader range of disciplines into LSC research with the ultimate aim of stimulating the development of novel, LSC inspired technologies.

“…Due to microalgae biomass and their pigments, the incident light which illuminates the reactor's surface exponentially decreases along the culture (Wagner, Valverde‐Perez, & Plosz, 2018). Consequently, microalgae in the deepest places of the reactor remain light‐limited or even in complete darkness, reducing microalgae productivity (Fernández et al, 2016; Raeisossadati, Moheimani, & Parlevliet, 2019). For this reason, light path in microalgae reactors tends to be short, that is, around 15–30 cm for raceway ponds (Acién et al, 2021; Arbib, de Godos, Ruiz, & Perales, 2017) and in the range of 2–10 cm for closed PBRs (González‐Camejo, Aparicio, et al, 2020; Slegers, Wijffels, van Straten, & van Boxtel, 2011).…”

Outdoor microalgae‐based urban wastewater treatment: Recent advances, applications, and future perspectives

et al. 2021

View full text Add to dashboard Cite

Although microalgae‐based wastewater treatment has been traditionally carried out in extensive waste stabilization ponds, recent trends focus on the use of microalgae to apply the circular economy principles in the wastewater treatment sector due to the capacity of algae to absorb carbon dioxide while recovering nutrients from sewage. To this aim, the development of new intensive microalgae‐based systems with higher efficiency and level of process control is required. Results obtained for these systems at lab scale are generally promising. However, upscaling to outdoor conditions is often uncertain. Some advances have been made in terms of applying open systems at large scale. However, there are still some issues related to land requirements and the economic feasibility and robustness of the process that have to be overcome to widely implement these systems. This article aims at describing the main design and operating factors regarding outdoor microalgae cultivation. It will also explain some microalgae cultivation technologies to treat wastewater, showing their advantages, disadvantages, and the possibility to treat different wastewater streams with microalgae cultures. Future perspectives of this biotechnology will be commented as well. This article is categorized under: Engineering Water > Engineering Water

“…In fact, light intensity, light frequency and photoperiods have been reported to influence microalgae productivity and nutrient removal efficiency [25,26]. Microalgae growth is proportional to light intensity until reaching a saturation point at which the photosynthetic activity of microalgae achieves their maximum value [27]. When it falls below this optimal value, microalgae growth will be limited [22,28].…”

“…On the other hand, if the light intensity values exceed the optimum, photosystem I (PSI) and photosystem II (PSII) will be damaged, causing microalgae photoinhibition [26,29]. Photoinhibition can be reduced by combining periods of high light irradiance with periods of darkness [27]. Since algae have been reported to respond to light intensity almost instantaneously [28], the temporary lack of light is considered to allow the dark reactions of photosynthesis, which are slower than the light reactions [30], to use the stored energy from light reactions [25] without the addition of extra photons that cannot be used for photosynthesis.…”

“…and its spectrum [40], which can negatively affect microalgae [29,41]. In addition, in high-dense microalgae cultures, the light is not uniformly distributed [27]. The cells close to the PBR surface receive high light intensities that can reach up to 1800 μmol•m −2 •s −1 at midday [13] and hence are likely to suffer from photoinhibition [27,42].…”

Effect of light intensity, light duration and photoperiods in the performance of an outdoor photobioreactor for urban wastewater treatment

et al. 2019

A series of eight experiments were carried out to analyse the effects of light intensity, light duration and photoperiods on a microalgae culture for treating AnMBR effluent at an outdoor photobioreactor (PBR) plant.Improved performance was achieved in terms of nutrient recovery rates, biomass productivity and effluent nutrient concentrations at a higher net photon flux. However, the higher irradiance was also responsible for lower biomass productivity:light irradiance ratios.None of the experiments with different lighting regimes and the same net photon flux showed any significant differences. The data obtained suggest that microalgae performance in this system did not depend on the time of day when light was applied or the length of the photoperiods, but on the net photon flux. No photoinhibiton was * Constant energy consumption of 0.8 KwhSolar light is the most economical option for outdoor microalgae cultivation [24,39], but variations in the weather, day:night cycles and seasonal changes affect light intensity
