METHOD AND APPARATUS FOR CONCENTRATING AN AQUEOUS SUSPENSIONOF MICROALGAE

摘要

The invention relates to a method and apparatus for concentrating an aqueous suspension of microalgae. The suspension of microalgae is passed through a tangential filtering device for partially removing water from the suspension without rupturing the microalgae, thereby obtaining a concentrate d suspension of microalgae and filtered water. The concentrated suspension of microalgae thus obtained is recovered. Such a concentrated suspension of microalgae can be used for feeding marine organisms or for extracting and/or isolating bioactive molecules. An apparatus for carrying out the method according to the invention is also disclosed.
