Product Description
Specification of Ion Exchange Unit
- Self-contained apparatus either for single bed water softening or double bed system for demineralisation.
- Two vertical transparent tubes house the resins.
- A manifold at inlet/outlet allows flow configuration changes.
- Equipment includes pump, valves, conductivity meter and sumps for regenerant and test or wash solutions.
- Typical commercial cation and anion resins are supplied.
Description of Ion Exchange Unit
- Two vertical transparent tubes mounted on a backboard contain the cation and anion resins. A manifold arrangement at the inlet and outlet to the tubes allows the flow configuration to be changed to simulate the cycles involved in the operation of a deioniser.
- Union couplings permit the tubes to be removed from the manifolds and interchanged for softening/demineralisation experiments.
- Regenerant and test or wash solutions contained in separate sumps are selected by a traversing tube and delivered to the apparatus by pump through a control valve and flow meter. Effluent may be fed to a sump tank and treated water collected in bottles for tests on hardness, conductivity or dissolved solids.
- A conductivity meter connected to the outlet of the second ion exchange bed gives a continuous indication of the progress of demineralisation. The apparatus is supplied with typical commercial cation and anion resins.
