Algae

Harvesting algae cultures more efficiently

Algae are all-purpose: algae is suitable as raw materials for food, biofuels, pharmaceuticals, cosmetics and more. In order to optimize the yield of raw materials, manufacturers need state-of-the-art harvesting technology. “Enalgy” stands exactly for this, the highly efficient, cost-saving algae harvesting with KOEN's separation technology.

Due to their positive attributes, algae are increasingly used in coal production to reduce CO2 emissions and in sewage treatment plants to reduce high nitrogen and phosphor levels. This green bioresource grows in culture ponds or in photobioreactors. During the harvesting, algae are separated from their culture substrate and processed further to become a high-quality concentrate. The harvesting technology used has a decisive influence on the efficiency of the overall process: The aim is to keep both the investment costs and the operating costs for energy, water, etc. as low as possible. At the same time, for optimal processing, the separated algae concentrate should have as high a dry matter content as possible.

The KOEN "enalgy process" offers a comprehensive solution for these algae harvesting requirements. In principle, two processes are possible, each using a high-quality KOEN centrifuge: A single-stage process with a KOEN separator is suitable for small to medium-sized operations.
