WebJun 13, 2024 · In Section 5.11, we discuss another simple flow stirred tank, called a continuous stirred-tank reactor (CSTR) or a capacity-flow reactor. A CSTR consists of a single constant-volume vessel into which reactants are continuously injected and from which reaction mixture is continuously withdrawn. The contents of this container are constantly … WebApr 3, 2024 · 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.

Web3.2.2 Sequencing batch reactor. Sequencing batch reactor (SBR) is a fill and draw type of activated sludge wastewater treatment method. SBR is similar to CAS in mechanism except all the treatment steps are performed in same tank in SBR method. Wastewater is treated in batches and for each batch, a series of treatment stages are sequenced.
