For algae value-added products, the quality of the algae paste is very important. Every step in the up- and downstream process should maximize the valuable components within the algae cell.

Evodos, an algae company based out of Netherlands has been manufacturing a harvesting equipment – Dynamic Settlers for the extraction of even the smallest algae (species of Nanochloropsis), fragile algae (species of Dunalliela and Diatoms) and both fresh and marine water algae are harvested succesfully.

The Evodos Dynamic Settlers, with the unique Spiral Plate Technology, outperform traditional separation/harvesting equipement. The separation efficiency is over 95%, and the dry weight of the output Algae paste is 1,5 – 2 times better compared to traditional centrifuges. Even more important, the Algae paste is of excellent quality, all algae cells are harvested intact and undamaged.

During the harvesting process, the algae don’t change in structure and temperature, the company claims that their harvesting equipment  is the only algae harvesting solution where all valuable components (ingredients) inside the Algae cells are fully retained. This significantly increases the value of the output Algae biomass.

The separation excellence of the Dynamic settlers is the result of fundamentally new hydraulics. The feedflow (Algae culture) and the drum rotate at the same speed. This is combined with a short settling distance, and a smooth discharge method. This is truly unique. The highly effective separation process takes place at only 3000 G’s. This is on minimal energy demand. The Evodos dynamic settlers are easy to connect and operate.

The Evodos harvesting equipment have been extensively used in the harvesting of:

• Nannochloropsis: high dry solid percentage 25-30%, excellent quality of the algae paste, all EPA retained
• Dunaliella Bardawil: dry solid content of 29%, high cell integrety after harvesting, glycerol and Beta-carothene (5,6%!) retained
• Diatoms: all diatoms cells (Bacillariophyceae) are harvested undamaged and intact. All valuable components in the cells are retained.
• Tetraselmis: harvested with an energy balance of 1.8%

Based on the innovative technology, continuous R&D and excellent output results, Evodos is selected and active partner in:

–       The Algae related EU-projects BIOFAT, FUEL4ME and D-Factory.

–       The Algae innovation projects at the Dutch Institute for Sustainable Process Technology (ISPT)

–       The US ATP3 program organized by Arizona State University

About the Company – Evodos is a company with a primary focus on the research, development and production of Algae harvesting equipment. Evodos excels in the separation excellence of the algae biomass.
