Claim 0:
1. An installation for treating a biological liquid by viral inactivation, comprising
a main supply valve for supplying a biological liquid to treat, configured to be connected to at least one source of biological liquid supply;
a first treatment line downstream of the main supply valve, the first treatment line including a first end coupled to the main supply valve, an opposite second end, and a first main treatment tank disposed between the first end and the second end of the first treatment line, the first main treatment tank being configured to be supplied by the main supply valve with the biological liquid to treat;
a second treatment line downstream of the main supply valve, the second treatment line including a third end coupled to the main supply valve, an opposite fourth end, and a second main treatment tank disposed between the third end and the fourth end of the second treatment line, the second main treatment tank being configured to be supplied by the main supply valve with the biological liquid to treat, wherein the second treatment line is in parallel with the first treatment line; and
a third main treatment tank disposed at the second end of the first treatment line and the fourth end of the second treatment line and which is further configured to be successively supplied by the first main treatment tank and by the second main treatment tank;
wherein the installation is configured such that in each of the 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 the biological liquid; and the installation is also configured to regulate a rate of drainage flow out of the third main treatment tank so as to provide a continuous rate of flow of treated biological liquid at an outlet from the installation.
