Inhibition of Enzyme Reactions in Continuous Stirred-Tank .

Three types of inhibition (competitive, uncompetitive, noncompetitive/mixed) and reaction with no inhibitor are compared for an enzyme reaction that obeys Michaelis–Menten kinetics. Substrate concentration is plotted versus time for a continuous stirred-tank reactor (CSTR) and for a batch reactor.

Batch reactors contain ports for injecting reactants and removing products, and can be outfitted with a heat exchanger or a stirring system. While batch reactors are generally of constant volume, some are designed to maintain a constant pressure by varying the reactor volume. The picture below shows the top of a batch reactor.

Wastewater Technology Fact Sheet: Sequencing Batch Reactors

Sequencing Batch Reactors DESCRIPTION The sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single "batch" reactor, treated to remove undesirable components, and then discharged. Equali zation, aeration, and clarification can all be achieved using a .

What Are Batch Reactors? (with picture)

Jun 02, 2020 · Batch reactors are tanks used to contain chemical or biological reactions. The term "batch" distinguishes this type of reactor from continuous reactors — in a batch reactor, all the necessary ingredients are placed in the tank and the chemical reaction or fermentation is allowed to take place, whereas in a continuous reactor ingredients are continuously fed into the tank.

Batch reactor - Wikipedia

A semi-batch reactor will have some addition and/or removal during the course of the reaction; a T-flask is a semi-batch reactor if media is changed between passages. Batch reactors can be operated as static or mixed; a T-flask is static (Fig. 3.1) and a stirrer flask, such as a Techne® Flask (Fig. 3.2) is mixed. Mixing helps remove .
