INSTALLATION FOR TREATING BIOLOGICAL LIQUID

The invention concerns an installation for treating biological liquid by viral inactivation, comprising a main supply valve (4) for suppling biological liquid to treat, a first line (2) downstream of said valve and provided with a first main tank (7), a second line (3) downstream of said valve and provided with a second main tank (14), said second line being in parallel with said first line, and a third main tank (11) disposed at an outlet both from said first line and said second line and configured to be successively supplied by said first main tank and by said second main tank; said installation being configured such that in each of said first, second and third main treatment tanks, a determined volume of acid and a determined volume of base are introduced at least so as to adjust a pH of said biological liquid and to regulate a rate of drainage flow of said third main treatment tank so as to provide a continuous rate of flow of treated biological liquid at an outlet from said installation.
