Anaerobic digestion of Ulva sp 3. liquefaction juices extraction by pressing and a technico-economic budget ArchiMer
Morand, Berenice; Briand, X; Charlier, R.
In many countries, the algae of "green tides" are harvested in the fight against pollution. Ulva often represents the main component of the tide, and intensive research has been conducted on the possibility to use the algae as a methanisation substrate. However, methanisation is hampered by various practical obstacles, which requires a compromise between productivity and biological yield. The process described here calls upon a pre-digestion phase of Ulva which, besides the economy of time and volume of the digestion, makes it possible to obtain a biogas of good quality. The methanisation substrate is the hydrolysis juice collected by draining, followed by pressing. The cake resulting from the pressing process can be used as organic enriching or...

Les marees vertes: Premier bilan concernant les essais de valorisation ArchiMer
Brault, D; Briand, X; Golven, P.
Seasonal green algal blooms (Ulva lactuca ) are observed along Brittany coasts and estuaries. The example of Lannion Bay during 1982 is exposed, with the causes and the consequences. After treatment, these seaweeds can be used for energy production (methanization and composting) and animal feeding (laying hens).
