Peristaltic Pump Requirements for an ED Plant

For my master thesis I am working on a simulation in Matlab/Simulink for an electrodialysis unit powered by a PV-system for brackish water.

I have been reading about the design of an ED system, but what are the most common requirements of peristaltic pumps?

Can anyone suggest where I can find this information? 

I am trying to make the simulation as simple as possible, I would not like to simulate all transport phenomena in the ED process since it would be out of the thesis scope.

1. Why use a peristaltic pump?  If you're concerned about brackish water only, use a centrifugal pump with a fiberglass head, since pressure or viscosity aren't big factors.  A positive displacement pump uses much more energy than a centrifugal pump.  if you can gravity feed out of a tank or have any head on the pump inlet, you can use a centrifugal.  I would imagine using PV, you need to save as much energy as possible.

2. What is the required flow rate? You may have pumping technologies choices beyond peristaltic to meet your application requirements. Valveless piston pumps from Fluid Metering have been a maintenance-free solution for concentrated hypochlorite metering for water treatment as well as metering methanol for wastewater denitrification.

   This gives details about requirements for peristaltic pumps

   1. informational article. thanks

4. First off, you need to know the flow rate. then choose tubing that will allow for the flow rate. and get a pump with the proper attachment for the tubing.  Measure and adjust the flow rate for the pump with the tubing and you're in business.

   1. Thanks for the input :)

5. You could contact to Prominent company. 

   You will find any equipment which water related.

   1. I will check that out! Thank you

6. To add to the advice already provided, I have found that such pumps are often selected with too high a pumping capacity. This means that they struggle to be sufficiently sensitive to provide the required dose rate often operating within 5 or 10% of their full capacity. I'd recommend designing to use full capacity or near to it as you can and maybe even select an option to have several pumps in parallel if there is a wide range of dosing flows needed. That way you will achieve much better control and the process will be better at meeting the need.

   1. Thanks for the advice!

7. Go to Wikipedia as horrible as it may sound and there is a good simulation.  They also known as a tube pump or positive displacement pump.  Very simple in operation.  Two wheels constantly rotate against a fixed tube and squash it flat forcing the liquid along the pipe.  It is that simple.

   1. Wikipedia is not that horrible as it sounds! Thanks

8. Check out the pump and filter we promote on my web site www.climatesmartirrigation.com

   it is a series of dialysis filters for potable use

   1. Sorry, but you haven´t understand the question - the filter system what you have advertised here isn´t an electrodialysis unit. You only use membranes for your system what was developed for the medicinal dialysis.

      1. It is for my master thesis. (I do not plan to buy anything). It is been developed a pilot electrodialysis unit for brackish water and for that is used a peristaltic pump and I would like to know more about those pumps in such systems. My question is about it.
