Chapter 1: Techniques
Permutit: Ion Exchange for Water Treatment
Permutit technology is built upon the principle of ion exchange. This process involves the use of specialized materials, known as ion exchange resins, to selectively remove unwanted ions from water and replace them with more desirable ones.
How it works:
- Ion exchange resins are typically made of synthetic polymers with a specific chemical structure. They have active sites on their surface that can attract and bind ions from the surrounding water.
- During the exchange process, the undesirable ions in the water (like calcium and magnesium causing hardness) are attracted to the active sites of the resin and bind to them.
- Simultaneously, the resin releases other ions (like sodium or potassium) into the water, essentially replacing the undesirable ions.
Types of ion exchange processes:
- Cation Exchange: This process primarily removes positively charged ions (cations) like calcium, magnesium, sodium, and potassium.
- Anion Exchange: This process focuses on removing negatively charged ions (anions) like chloride, sulfate, and nitrate.
- Mixed Bed Ion Exchange: This method combines both cation and anion exchange resins in a single vessel to achieve complete demineralization of water.
Regeneration:
- After the resin becomes saturated with undesirable ions, it needs to be regenerated to restore its capacity.
- Regeneration involves flushing the resin with a concentrated solution of the desired ion, reversing the exchange process and releasing the captured unwanted ions.
Permutit technology offers a flexible and efficient approach to water treatment, offering a range of benefits for various applications.
