As name implies the reactor is well mixed, allowing the assumption of same concentration at any point within the reactor and the product. A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state ( Q in = Q out = Q ). The main assumption in this case is that the concentration of the incoming fluid will become CSTR reactors are batch reactors with an open systems and have impeller equipped with it to provide agitation for proper mixing or reactor content. these reactors allow adding continuous raw material into the reactor and continuous removal of product.

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. 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). Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed. Reactor Sizing Given –rAas a function of conversion, –rA = f(X), one can size any type of reactor. The volume of a CSTR can be represented as the shaded areas in the Levenspiel Plot shown below: Approach to steady state in a continuous stirred tank reactor (CSTR).

In this paper, a differential equation system that describes the substrate, biomass and  for multiple reaction types, and for several types of reactors, i.e. batch (BR), semibatch (SBR) and continuous stirred tank reactor (CSTR) has been developed.

It is assumed of having no spatial variation in concentration and temperature. As name implies the reactor is well mixed, allowing the assumption of same concentration at any point within the reactor and the product. Model a CSTR reactor with PHREEQC. A continuous-flow stirred tank reactor (CSTR) is widely applied in chemical- and bio-engineering for water treatment and making chemicals.

Su nombre real es el de reactor de tanque con agitación continua (CSTR), por sus iniciales en inglés, aunque también se le conoce como reactor de mezcla completa de flujo continuo o reactor de tanque agitado.

The main assumption in this case is that the concentration of the incoming fluid will become CSTR reactors are batch reactors with an open systems and have impeller equipped with it to provide agitation for proper mixing or reactor content. these reactors allow adding continuous raw material into the reactor and continuous removal of product. H20 CSTR process for industrial and domestic wastewater treatment H2O CSTR is completely-mixed form of anaerobic reactor, designed to maximize the contact between the biomass and the waste, to optimize digestion performance. CSTR digester configurations, it is also one of the best in terms of applicability to different wastes. A continuous stirred tank reactor (CSTR) is a batch reactor equipped with an impeller or other mixing device to provide efficient mixing.

Based on Figure, reactor 1 is the closest to ideal CSTR since the curve flow decreases over time compared to bell shape curve for reactor 2 and reactor 3.However, throughout the curves values, E (t) curve for Reactor 2 shows the highest value which signifies the higher rate of mixing compared to the other two reactors.The first moment to be considered in the Residence Time Distribution (RTD) function is the mean residence time, tm. In a CSTR, one or more fluid reagents are introduced into a tank reactor which is typically stirred with an impeller to ensure proper mixing of the reagents while the reactor effluent is removed. Dividing the volume of the tank by the average volumetric flow rate through the tank gives the space time , or the time required to process one reactor volume of fluid.
