SCADA (supervisory control and data acquisition) is used in bioreactors to collect, transmit, and manage a variety of parameters that are important to the production of cultures in the bioreactor including nitrogen requirements; amino acid supplements; temperature; pH; oxygen concentration; pressure.

What is the uses of SCADA?
The uses of SCADA-Supervisory Control And Data Acquisition, is to manage equipment and to automate complex industrial processes.
Why do chemical engineers need to study microbiology?
because bacteria and fungus can be used in bioreactors for obtaining products such as vitamins, aminoacids, foods, beverages and secondary metabolites
What are enzyme reactors?
An apparatus, such as a large fermentation chamber, for growing organisms such as bacteria or yeast that are used in the biotechnological production of substances such as pharmaceuticals, antibodies, or vaccines, or for the bioconversion of organic waste.
What is the equation for reaction rate?
. The transformation of glucose into fructose by the enzyme glucose isomerase, was carried out in two different types suspended-enzyme bioreactors: 1) CSTR, and 2) plug flow reactor. The process obeys Michaelis-Menten kinetics. The following parameters and kinetic constants were kept the same in both bioreactors: $ So (input substrate concentration) = 1.0 mMol/L; $ F (volumetric flow rate) = 1.0 m3/h; $ Km = 7x10-4 Mol/L; $ Vmax = 0.2 mMol/(L.h) Determine: $ Volume of CSTR for 50% conversion of glucose; $ Volume of PFR for 50% conversion of glucose; $ Volumes of CSTR and PFR in series (assume that the volumes are equal) in two cases: $ first CSTR $ first PFR 2. Calculate the volume of a stirred tank bioreactor containing the same enzyme, but immobilized on the surface of a flat-geometry support. The value of the mass-transfer coefficient is 0.6 h-1. The values of the rest of process parameters are the same as above.
What are the advantages and disadvantages of using continuous culture.?
adv and disadvantages of continuous cultThe advantages include: Cells can be maintained at a constant physiological state because the specific growth rate and the substrate concentration can be set simply by setting the dilution rate (µ = D)Continuous cultures can take advantage of cell immobilization which allows the maintenance of high concentrations of cells in the reactor at low substrate concentrationsMost downstream processing operations (apart from chromatography) operate in a continuous manner. Continuous bioreactors thus fit in will with overall operation of a bioprocess plantContinuous reactors do not need to be shut down and cleaned as regularly as a batch reactor and thus have a shorter "turn-around" time. This also reduces costs associated with cleaning and filling of the reactor.The above advantages give continuous bioreactors a greater productivity than batch bioreactors and thus continuous reactors can be smaller (and thus cheaper) to construct and operateThere are number of reasons why continuous cultures are not widely used in industry. These include:Continuous cultures are unsuitable for products which are predominantly produced when growth ceases. Such products include many antibiotics, toxins produced during endospore production by Bacillus spp. and Clostridium spp. and monoclonal antibodies.When growth ceases, the specific growth rate (µ) = 0. Since at steady state the specific growth rate = dilution rate, any dilution rate greater than zero will cause the population to be washed out. (If µ < D the cells will be washed out).They are unsuitable for producing various fermented foods and beveridges which depend on a complete batch cycle to produce full flavours. You should remember that unlike a batch culture, a continuous culture maintains the cells at a single physiological state (ie. the specific growth rate is set by the dilution rate :µ = D)Contamination or mutation can have a disasterous effect on the operation of a continuous cultures, especially if the contaminant or mutant is able to maintain a lower concentration of the growth limiting substrate than the desired organism.The US-FDA at present will not approve the liscencing of pharmaceuticals produced in continuous cultures. This is because pharmaceuticals must be able to be linked to a batch identification. This is not as easy with continuous cultures.Large scale continuous cultures are still regarded as risky ventures. Many managers are unwilling to take such risks.
What makes PLC communicate with SCADA?
There are different communication protocols between PLC and the SCADA. Popular SCADA being PC based, most used communication protocol is ethernet/IP. The PLC tags are used to build the objects in SCADA so that Actions or states or status or parameters of PLC are displayed on SCADA.
Describe what SCADA software can be used for?
SCADA software can be used for monitoring system processes. Some examples of processes that the software can surveil are industrial, infrastructure and facility processes.
Who invented scada and When scada was discovered?

What type of instrument is the Scada Control?
Scada control is a type of instrument that used in industrial. This type of instrument is based on computer system that control data acquisition for the industrial.
When was PROMOTIC SCADA system created?
PROMOTIC SCADA system was created in 1991.
How you define SCADA?
SCADA is an acronym for Supervisory Control and Data Acquisition. SCADA usually refers to an industrial computer system that monitors and controls a process.
What does SCADA systems offer?
Supervisory control and data acquisition is a type of industrial control sytem. The SCADA can be used to convert sensory data into digital data and sending it to the supervisory system.
What do SCADA systems control?
SCADA stands for supervisory control and data acquisition, a computer system for gathering and analyzing real-time data. SCADA systems are used to monitor and control a plant or equipment in enterprises such as telecommunications, energy, oil and gas refining, water and waste control, and transportation.
What is SAP with respect to SCADA systems?
HI guys I have a question:what is SAP with respect to SCADA system?
When was Scada Security invented?
SCADA Security was established in the early 2000's. This is a computer based security system that ties together power, oil, and gas pipelines. They are used by many businesses in the US.
Who discover the scada?
Salil Khare from India is normally credited for the initial works in the field of developing SCADA systems
