Algae: Raceway to the future? | IATP

    https://www.iatp.org/blog/201510/algae-raceway-to-the-future
    Some of the topics discussed included the open pond raceway design to reduce energy use by a factor of ten, technology to increase the efficiency of the capture and use of CO2 by a factor of fifteen and algae harvesting and dewatering technology to increase primary harvesting by a factor of eight over conventional algae technology.

Sandia National Laboratories: News Releases : Algae raceway …

    https://newsreleases.sandia.gov/algae_raceway/
    The new algae raceway testing facility at Sandia National Laboratories may be oval in shape, but it paves a direct path between laboratory research and solving the demand for clean energy. As the nation and California adopt policies to promote clean transportation fuels, that path could help bring the promise of algal biofuels closer to reality

    BETO-funded projects will begin using the algae raceway immediately, including a project that seeks to convert algae proteins into useful chemical compounds such as butanol (an alcohol that can be used as a transportation fuel) and a project with Lawrence Livermore National Laboratory investigating a probiotic approach to algae crop protection. BETO has …

Algae Basics - Production Systems of Algae

    http://allaboutalgae.com/open-pond/
    Open pond systems use shallow (typically one-foot deep) ponds, from about one acre to several acres in size, in which the algae are exposed to natural solar radiation (sunlight) which they convert into biomass. Typically the ponds are called raceway ponds because their shape resembles a race track.

Raceways – Freshwater Aquaculture

    https://freshwater-aquaculture.extension.org/raceways/
    In most raceway systems, dissolved oxygen is replenished by allowing the water to fall into subsequent tanks within the raceway. Dissolved metabolites from animals in the system are carried out in the effluent, while settleable particulate wastes can be captured by settling or less frequently by other means of filtration.

    The water is often divided into concentric lanes or raceways, with paddlewheels to move the algae mixture in a circle. This helps bring algae to the surface, where they're exposed to light, and mixes nutrients and carbon dioxide into the liquid. The open-pond method produces less algae biomass than other methods.

Micro Algae in Open Raceways | SpringerLink

    Benemann in 2008 compared the economies of open ponds with closed bioreactors . Growing microalgae in bioreactors is a high yielding technology (0.5–8 g/l), low risk of contamination, but expensive ($ 250,000–1,000,000/ha) with an expected approximate life span of 10–15 years for the bioreactors.

Raceway (aquaculture) - Wikipedia

    https://en.wikipedia.org/wiki/Raceway_%28aquaculture%29
    A raceway, also known as a flow-through system, is an artificial channel used in aquaculture to culture aquatic organisms. Raceway systems are among the earliest methods used for inland aquaculture. A raceway usually consists of rectangular basins or canals constructed of concrete and equipped with an inlet and outlet. A continuous water flow-through is maintained to …

Microalgae culture in raceway open ponds for bioenergy production

    Current systems for algae biomass production include photobioreactors and raceway open ponds. Raceway open ponds – The benefits and costs Open raceways are typically made of a closed loop, oval shaped recirculation channels, filled with large water volumes at low depths over high surface areas, with adequate mixing and circulation to maintain microalgae …
