Ion Exchange Resins

The principle of Ion Exchange Resin is to replace ions from a solution with other ions in the treatment process. This is led by the concept of specificity and selectivity toward the target species. The resin will exchange their ions (Na+, H+, OH-,...) with the ions to be removed from the stream. The ion exchange plants are designed based on the specifications of the stream in order to provide the highest quality in the treatment at the lowest Capex and Opex. The process of separation by the resins lasts until exhaustion of the resins exchange capacities, after which they can be regenerated with certain regenerants for a new cycle. This ensures that the resins can be reused thousands of time which is very advantageous in terms of cost saving.

There is 3 main family of resins:

1. CATION EXCHANGERS (large portfolio of strong and weak acids)
2. ANION EXCHANGERS (large portfolio of strong and weak bases)
   Mixed beds are a mixture of Strong Cation and Anion exchangers.
3. SELECTIVES ION EXCHANGER (chelating resins with specific functional groups)

• Robust and high-performance technology
• High yield with minimal wastes
• Stable and consistent quality due to high reliability of the process and resins
• Capability to remove traces of target contaminants

• Water softening
• Demineralization
• Mixed bed polishing
• Contaminant removal (PFAS, Boron)
• Industrial and utility process water treatment (power plants)
• Heavy metal removal (Fe, Cu, Hg, Cd, Pb, Ni, Zn,…), 
• Ultra-Pure Water
• Organic Scavengers (NOM) 

Ready to use mixed bed are pre-mixed resins with different ratios of cation and anion depending on the application it will be used. This system will allow you to get a high-quality purified water (conductivity <0.1mS). Its advantage compared to other technologies like the reverse osmosis, for example, is the high efficiency of the demineralization process as well as the fact that resins can be regenerated. It can be used in small system as well as bigger industrial scale. Three type of resins are in our portfolio for this application: 

MB100: specific for Electro-erosion machines (internal close purification circuit)

MB200: general demineralization application

MB300: specific for heating circuit

PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals containing carbon-fluorine bonds, which are the strongest chemical bonds in organic chemistry. Due to their unique and desirable properties, PFAS are widely utilized in various industries including food contact materials, textiles, aerospace and defense, automotive and semiconductor industry.

The majority of PFAS are persistent in the environment and are commonly referred to as "forever chemicals". Certain PFAS are also easily transported in the environment, covering long distances from the source of their release. As a result, PFAS contamination of soil, groundwater and surface water is a frequent occurrence.

Several solutions are available to mitigate the presence of PFAS in water. One such solution is the use of Ion Exchange Resin, a proven technology for capturing small PFAS molecules. Our range includes two products specifically designed for this application: Treverlite XS130800 & Treverlite XS133100. You can find further information in our brochure.
