Separation Technology for Algae Production
English, 6.56 MB
Today, the rate of algae production worldwide is already between seven and eight million tonnes per annum. To be able to satisfy this high demand whilst operating with maximum economic efficiency, more and more companies are turning to centrifugal technology from GEA Westfalia Separator Group.
The separators and decanters specifically developed for treating fermentation products are being used for concentrating, extracting and washing the algae. The centrifuges are suitable for plants producing algae in open ponds and also for closed systems using photobioreactors, where improved light conditions and reduced risk of contamination are advantages over open ponds. For the concentration process there are separators of various models to choose from, each with its individual advantages according to algae type and cultivation conditions.
Which separator and which processing material provide the best possible performance in any particular case depends not just on the capacities to be handled, but also on numerous other factors such as the product’s viscosity, the solids content, the pH value in the fermentation broth or the particular cell structure. Corrosion-resistant high-alloy special steels are used to meet the special requirements of salt algae fully.
GEA Westfalia Separator Group also offers decanters for the concentration and dewatering of biomass as well as to classify micro algae.
