2005-2008: The beginnings of the scientific duo

Julien Jacquety, founder and manager, leaned over the column when he was an engineering student in aquaculture. During an internship, he must operate the process devised by two researchers, François René from the IFREMER station in Palavas-les-Flots and Jean-Yves Champagne from INSA in Lyon. During this period, he made the acquaintance of Bertrand Barrut, also in internship, who intends to carry out a thesis on the famous column.
The transition from theory to practice took place in 2005 thanks to the pair who designed the first prototype. This is the start of the adventure!

In 2006 additional tests made it possible to validate the efficiency of the process for its three functions and thus to write the first patent for the vacuum column filed the following year (No. 07 02308).

In 2007, Julien Jacquety and Bertrand Barrut again confirmed all of his results in the treatment of water from recirculating aquaculture farms, in temperate conditions at IFREMER, in tropical conditions at ARDA in Reunion Island. .

In 2008, Julien Jacquety decided to create COLDEP and started its incubation within CREALYS in Lyon. Bertrand Barrut, he is starting his thesis on the vacuum column process which will validate the interest of the process with the scientific community.
