Continuous stirred-tank reactor - Wikipedia

Continuous stirred tank reactor (CSTR) is the most generally employed bioreactor for biohydrogen production in continuous mode because of its simplicity in configuration, easy functioning, efficient uniform stirring, and proper maintenance of temperature and pH (Fig. 10.2A).In these types of bioreactors, biohydrogen generating microbial population is entirely circulated and is in suspension .

Continuous Stirred Tank Reactor. The continuous stirred tank reactor (CSTR, or simply the stirred tank reactor, STR) is essentially similar to the batch reactor, with the main important difference is that, for the stirred tank reactor, provision must be made for continuous flow of material into and out of the reactor by gravity flow or forced-circulation flow with a pump.

The most common continuous-flow system in biodiesel production is the continuous stirred-tank reactor (CSTR). At first glance a CSTR, such as that shown in Figure 1, appears to be identical to a batch reactor. In fact, often the actual reactor may be the same, but additional controls are needed to set the reactor up in a continuous-flow system.
