Algae Harvesting and Separation

The concentration of algae in the water is usually dilute, and the biomass recovered from the dilute medium accounts for 20-30% of the total production cost. Algae can be harvested using: 1) sedimentation (gravity sedimentation), 2) membrane separation (microfiltration/ultrafiltration), 3) flocculation, 4) flotation and 5) centrifugation. Seaweed (macroalgae) is considered a sustainable biological resource, rich in high-quality nutrients such as protein. Seaweed protein can be used as a substitute for other protein sources. If the seaweed is contaminated, CD BioSciences can use certain methods to isolate the desired seaweed individuals from the mixed biota in natural waters to obtain monoclonal culture. The diverse metabolism of microalgal species also provides opportunities for product recycling in the feed, food, nutraceutical, cosmetic, and biopharmaceutical industries. If the microalgae are contaminated by bacteria or other algae, CD BioSciences will provide a suitable pharmaceutical solution for your purification of algae species; or isolate the algae species, and then separate the useful algae species for cultivation and purification.

Algae Harvesting and Separation Technologies

• Sedimentation
  Sedimentation is the initial stage of the separation of algae from the water. After agitation is complete, allow the algae to settle and densify.
• Membrane separation
  This method can be used to collect microalgae at low densities but is usually performed on a small scale. But the main disadvantage is membrane fouling.
• Flocculation
  Flocculation is another technique. Flocculation is a method of adding something to a mixture of water and algae that causes the algae to "clump" together (or aggregate) and form a colloid.
• Froth floatation
  Froth flotation is another method of harvesting and separating algae from the water. For algal systems, where the algae build up on top with the foam of the bubbles, there are ways to collect or scrape the foam and algae from the top to separate it from the water.
