ION EXCHANGE PILOT MP11

This pilot enables understanding of the operations offered by ion exchange : - water softening, where all the alkaline earth elements are replaced by sodium - demineralisation, where all the cations are replaced by hydrogen ions and all the anions by hydroxide ions - decationisation, where all the cations in the water are replaced by hydrogen ions.

Teaching objectives

- According to the analysis of the water and flow to be treated or the desired quality to obtain, one can choose :

- the resin to test
- the type of regenerating,
- the quantity of regenerating,
- the flow and function type (co-current, counter-current).

- Measuring the resin capacity according to the regeneration and then calculation the material balances (Ca²+, TH, TA, TAC).

 

Technical specifications

- Two Altuglass columns (for regeneration).
- Two Altuglass columns (for processing).
- The columns are removable to change the resins.
- 1 litre of anionic resin.
- 1 litre of cationic resin.
- 1 polypropylene centrifugal pump.
- 5 transparent PVC tanks
- 1 Conductivity measuring sensor with digital display
- Five measuring sensor layouts. The measuring sensors are moved in the layouts according to the chosen processes.
- Two fluid circuits to feeding the columns either in co-current or counter-current mode.
- Control panel including a synoptic with diodes to improve the circuit understanding according to the different regeneration /processing stages. It includes the pump control and safety protection, the conductivity measuring transmitters. All the piping is in PVC, the pilot is mounted on a stainless steel frame.

Option : another conductivity measuring sensor with digital display
