Ion Exchanger Unit is designed to demonstrate the purification of water or other liquids by removing ions or contaminants through an ion exchange process. It utilizes ion exchange resin to selectively attract and retain unwanted ions, replacing them with more desirable ions. It is widely used in industries such as water treatment and chemical manufacturing. The ion exchange process is mostly utilized for desalination.
- The trainer is used in water treatment, specifically for desalination and softening.
- It permits the demonstration of these processes using cation and anion exchangers.
- A pump is used to move up the raw water from the tank into the cation exchanger from the top.
- During the softening phase, the water flows back into the collection tank.
- To desalinate the raw water, it is passed through an anion exchanger.
- The treated water is then sent to the collection tank.
- During the regeneration process, the same pump feeds acid or caustic into the ion exchangers.
- The acid and caustic solutions are collected in the collecting tank.
- The pump's flow rate is adjustable and can be measured using a flow meter before entering the first ion exchanger.
- A conductivity sensor is put upstream of the collecting tank's inflow to allow for continuous process evaluation.
- The measured values can be read using a conductivity meter.
- Samples can be collected at all essential sites.
- Tap water can be used as raw water.
- The trainer has a tank with four chambers: raw water, rinse water, acid, and caustic.
- There is a diaphragm pump on the trainer to transport caustic, acid, rinse water, and raw water.
- There is a tank for collecting treated water, rinsing water, acid, and caustic.
- The trainer also includes
- Conductivity sensor
- Cation exchanger
- Anion exchanger
- Flow meter
- Pump
