Pilot scale photobioreactor system for land-based macroalgae cultivation

چکیده
Abstract Marine macroalgae such as Ulva intestinalis have promising properties feedstock for cosmetics and pharmaceuticals. However, since the quantity quality of naturally grown algae vary widely, their exploitability is reduced – especially producers in high-priced markets. Moreover, expansion marine or shore-based cultivation systems unlikely Europe, sites either lie fishing zones, recreational areas, natural reserves. The aim was therefore to develop a closed photobioreactor system enabling full control abiotic environmental parameters an effective reconditioning medium order produce at distant from shore. To assess feasibility functionality chosen technological concept, prototypal plant has been implemented central Germany site sea. Using newly developed, submersible LED light source, experiments with led growth rates 7.72 ± 0.04 % day ?1 cycle 28 days. Based on space demand production system, this results fresh mass productivity 3.0 kg m ?2 , respectively, 1.1 per year. Also considering ratio biomass energy input amounting 2.76 g kWh significant future improvements developed should include optimization parameters, reduction system’s overall demand.

A novel horizontal photobioreactor for high-density cultivation of microalgae.
Microalgae are a promising source of biofuels and bioproducts, as they consume CO2 to grow, multiply quickly, and can be cultivated in wastewater and on marginal land. Development of low-cost and high-efficiency microalgal cultivation systems is important to the cost-competitiveness of algae. A floating horizontal photobioreactor (HBR) was developed that is inexpensive and scalable, as it is ma...
متن کامل[A novel flat plate photobioreactor for microalgae cultivation].
Flashing light effect on microalgae could significantly improve the light efficiency and biomass productivity of microalgae. In this paper, the baffles were introduced into the traditional flat plate photobioreactor so as to enhance the flashing light effect of microalgae. Making Chlorella sp. as the model microalgae, the effect of light intensity and inlet velocity on the biomass concentration...

This paper describes an interactive virtual laboratory for experimenting with an outdoor tubular photobioreactor (henceforth PBR for short). This virtual laboratory it makes possible to: (a) accurately reproduce the structure of a real plant (the PBR designed and built by the Department of Chemical Engineering of the University of Almería, Spain); (b) simulate a generic tubular PBR by changing ...
متن کاملLand Suitability Classification for Persian Walnut Cultivation in Iran Using Geographic Information System (GIS)
The efficient use of water resources, soil, and climate parameters as the main pillars of plant sustainable production requires land suitability evaluation for each crop and area. This research was conducted to evaluate land suitability for walnut cultivation in Iran using geographic information system (GIS). For this purpose, the climate data obtained from 375 synoptic stations of Iran, the ge...
