What is Algae? Algae are simple, flowerless aquatic organisms that are diverse and widespread throughout the planet and play an important role in the aquatic food chain. Algae produce about 70% of the oxygen in the atmosphere, and they can be mainly classified as microalgae and macroalgae. What Can Algae Do? Single-celled microscopic algae are called microalgae and multicellular filamentous, ...
Algae are considered water pollutants because they form algal blooms in stagnant water. Algae harvesting technology, however, can help convert them into a useful industrial material like biomass. The core technique (flocculation) separates microalgae from other flocculants, allowing for the harvest of clean and pure algal biomass. This study aims to estimate and evaluate algal separation ...
On July 14, 2016, the U.S. Department of Energy (DOE), announced $15 million in funding for three projects that will work to improve algal biomass yields to reduce production costs of algae-based biofuels and bioproducts. The projects include Global Algae Innovations (San Diego, California), Algenol Biotech LLC (Ft. Myers, Florida), and MicroBio Engineering, Inc. (San Luis Obispo, California). ...
The effect of chemical coagulation and biological auto-flocculation relative to zeta potential was examined to compare flotation and sedimentation separation processes for algae harvesting. Experiments revealed that microalgae separation is related to auto-flocculation of Anabaena spp. and requires chemical coagulation for the whole period of microalgae cultivation. In addition, microalgae ...
Global warming due to the burning of fossil fuels is now widely recognized as a problem, and among the alternatives to fossil fuels, the extraction of fuel from micro algae has been actively investigated in recent years. While the yield per unit area of micro algae is high, and harvesting is possible year round, these advantages are offset by ...
Microalgae have been regarded as a pollutant causing algal blooms in lakes or reservoirs but have recently been considered as a useful source of biomass to produce biofuel or feed for livestock. For the algae particle separation process, carbon dioxide (CO2), one of the main greenhouse gases, is dissolved into a body of water rather than being emitted into atmosphere. This study aims at ...
Originally we only offered the flat bottom tanks in our line of tanks. Eventually, fit was discovered that they are ideal for growing algae with natural sunlight, however some growers wanted to something a little more. Several customers wanted an easier way to harvest the algae from the growth chambers, particularly the bottom. Siphoning works for the flat bottom tanks, and is a great option for ...
We examined the effects of pre-oxidation using ozone (O3) and a combination of O3 and hydrogen peroxide (O3/H2O2) on algae suspensions and their harvesting. Inactivation of algae cells, release of intracellular organic matter (IOM), mineralization of extracellular organic matter (EOM), and changes in molecular weight distribution of EOM were found after pre-oxidation. Enhanced separation ...
