Ion Exchange Chamber ENV 013

Ion Exchange Chamber ENV 013

Ion exchangers are used in water treatment primarily for desalination and softening. Sci-tech Ion Exchange Chamber Model ENV 013 enables these processes to be demonstrated with the aid of cation and anion exchangers.

Features
– Softening and desalination of water by ion exchange
– Regeneration of ion exchangers
– Cation and anion exchanger

Item Description

The raw water is pumped from the tank into the top of the cation exchanger. In the softening process the water flows from there back into the collecting tank. To desalinate the raw water, it is then additionally routed through the anion exchanger. From there the treated water passes into the collecting tank. In the regeneration process, acid or caustic is fed into the ion exchangers from below using the same pump. The acid and caustic used is collected in the collecting tank.
The flow rate of the pump is adjustable, and can be read from a flow meter before it enters the first ion exchanger. For continuous evaluation of the process, a conductivity sensor is installed upstream of the inlet into the collecting tank. The measured values can be read from a conductivity meter. Samples can be taken at all relevant points. Tap water can be used as raw water.
