Automatic Separating Disc Centrifuge for Marine Algae/Seaweed Extraction

Algae are marine creatures which can survive and grow in many other environments. It is a very important raw material used in feeding of marine animals such as shrimp, fish larvae, rotifer. It is extensively used for production of marine animal feed production and as soil enriching fertilizer in agriculture. It is also used in energy, chemistry, cosmetics, pharmaceutical chemistry, waste treatment, tooth care and alcohol industry.

Due to fast development of agriculture and fast increase in production demand, yield of agricultural areas is desired to be at utmost level. Microalgae improve the soil quality and fertility significantly.

Algae harvesting with the Shenzhou Separator

The algae suspension flows from the photobioreactor directly into the Shenzhou Separator. Then the distributor gently accelerates the suspension to full speed. Due to the high centrifugal force of up to 12,000 g, the separator dewaters the algae suspension producing an algae concentrate with creamy consistency. Thus making the algae concentrate ideal for further processing. Small to medium-sized plant benefit in particular from the low investment and low operating costs of the single-stage process.

• up to 25 percent lower investment costs

• lower costs for further processing or drying due to a very high-quality algae concentrate

• suitable for medium and small businesses

 Algae harvesting with the Decanter centrifuge

Algae harvesting with the decanter centrifuge is a two-stage process that is ideal for larger operations: The algae suspension from the photobioreactor is initially pre-concentrated. The algae concentrate then flows on into the Shenzhou decanter centrifuge, where the cell harvesting takes place. The decanter centrifuge dewaters the algae concentrate to a compact cake with 22 to 25 percent dry substance content. Only this special decanter centrifuge is capable of thickening the fine and soft algae cells in such an efficient way.

The pre-concentration in the two-stage process saves energy when compared with single-stage processes. The more water that is separated beforehand, the less the centrifuge has to separate.

• up to 60 percent lower operating costs (e.g. energy)

• up to 25 percent lower investment costs

• 22 to 25 percent high dry solids content for optimum further processing
