Microalgae have happened widely used in industrial requests around the realm for centuries, but large-scale nurture of algae in photobioreactor (PBR) is still backing many challenges in terms of cost of construction, order size, culture sustainability, and output. The production of algal feedstock is prevented by the inability to change laboratory studies into field scaleups. This stage focuses on the research conducted for the construction of a cheap flat panel PBR structure and optimisation of its operational plans. The microalgal strain chosen for mass nurture is the indigenous halophilic variety, Pseudanabaena limnetica (Lemm.) Komárek, which can withstand extreme heat and high light force in summer season and can be of age in seawater. Therefore, evident seawater has happened used in this research study of economical biomass production. Three scales of airlift panels have existed developed for the flat panel PBR method, ranging from 8L up to 250L. The ranges of the airlift panels are as follows: 1st : 25 cm x 38 cm x 10 cm (8L), 2nd : 50 cm x 70 cm x 20 cm (60L), 3rd : 100 cm x 110 cm x 28 cm (250L). A study was attended to optimize the air flow rate and the size of the sparger pore for enough aeration (CO2) and mixing. Physical parameters like, Sparger speed (v) m/s along with change in Reynolds number (Re), detail velocity of gas (Usg), vapor holdup (ε) was studied for their effectiveness to support algal growth. Likewise, optimization of other main parameters like light force, inoculum size was carried out in workshop condition and correlated with the biomass result. Each PBR was operated nature after optimization. Energetic power devouring was also discussed in addition to its cost estimation and total biomass output as well as the functional feasibility of the PBR systems grown. After optimizing the functional strategy for the working of PBRs in testing room and outdoor environments, it was found that 60L flat panel was ultimate suitable for large-scale sophistication of P. limnetica. Therefore, attempts have existed made to construct and congregate 1000L PBR using 60L PBR wholes in outdoor conditions.
