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.

Permutit Models: Tailored Solutions for Diverse Water Treatment Needs

Permutit technology encompasses a variety of models, each designed to address specific water treatment challenges. These models differ in their resin types, operating principles, and intended applications. Here are some common models:

1. Water Softening:

• Resins: Cation exchange resins, typically sodium-based.
• Function: Removes calcium and magnesium ions, responsible for water hardness, by replacing them with sodium ions.
• Applications: Domestic water softening, industrial water treatment for boilers and cooling systems.

2. Dealkalization:

• Resins: Strong base anion exchange resins.
• Function: Removes bicarbonate ions, reducing alkalinity and preventing scaling in boilers and other systems.
• Applications: Boiler feedwater treatment, industrial water treatment for cooling towers.

3. Demineralization:

• Resins: Mixed bed ion exchange resins, containing both cation and anion exchange resins.
• Function: Removes all dissolved minerals, including both cations and anions, producing high-purity water.
• Applications: Pharmaceutical manufacturing, electronics industry, high-pressure boiler feedwater.

4. Specialty Resins:

• Resins: Tailored resins designed for specific applications.
• Examples:
  • Heavy metal removal: Resins with high affinity for heavy metals like lead, cadmium, and arsenic.
  • Nitrate removal: Resins designed to remove nitrate ions from drinking water.
  • Dechlorination: Resins that remove chlorine from water, protecting pipes and preventing taste and odor problems.

Choosing the right Permutit model depends on the specific water quality requirements and the intended application. Each model has its unique advantages and limitations, and selecting the most appropriate one ensures optimal performance and cost-effectiveness.
