Mixed bed is typically cation and anion ion exchange resin all in one mixture.

Mixed bed ion exchange resins are mainly used in the water purification industry for polishing process water to achieve demineralized water quality, usually after a reverse osmosis system.

The Mixed bed Resins are the typical resins with mixture of strong acid cation resins in H+ form and strong base anion resins in OH- form. The ratio of component resins is designed to provide high capacity depending on the application.Several mixed bed resins are available with indicator which facilitate the operation because of color change when exhaustion.

The two resins are mixed to be used in one column for fully purification of water, to reduce the water conductivity. The mixed bed resins are usually used in the Electrical Discharge Machining plant for water demineralization.

How Do SEPLITE® Mixed Bed Ion Exchange Resins Work?

The ion exchange process in a mixed bed system is both simple and highly effective:

• Ion Attraction: As water flows through the resin bed, cations are drawn to the negatively charged cation resin, while anions are attracted to the positively charged anion resin.

• Ion Exchange: The cation resin releases H⁺ ions in exchange for cations, and the anion resin releases OH⁻ ions in exchange for anions. This simultaneous exchange removes ionic contaminants in a single pass.

• Pure Water Production: The released H⁺ and OH⁻ ions combine to form H₂O, leaving behind water with minimal total dissolved solids (TDS) and ultra-low conductivity.

This continuous, unified purification process makes SEPLITE® mixed bed resins exceptionally effective for applications requiring the highest water purity, such as boiler feedwater in power plants or ultrapure water in electronics manufacturing.

Key Features of SEPLITE® Mixed Bed Ion Exchange Resins

SEPLITE® mixed bed resins stand out due to their advanced design and superior performance:

• High Capacity: Engineered for maximum ion exchange capacity, our resins provide long service life and reduced regeneration frequency, lowering operational costs.

• Customizable Ratios: Available in various cation-to-anion volume ratios, such as 1:1 (SEPLITE® MB10IND) for balanced exchange and 1:2 (SEPLITE® MB30IND) for enhanced anion removal, tailored to your specific needs.

• Industry Certifications: All SEPLITE® resins meet rigorous global standards, including Rohs testing, FDA registration, WQA Gold Seal Certificate, and REACH compliance, ensuring safety and reliability.

• Color-Indicating Options: Select SEPLITE® resins feature a color indicator that changes when the resin is exhausted (e.g., from purple to amber), simplifying monitoring and maintenance.

Typical Applications For Mixed Bed Ion Exchange Resins

• Water Deionization: SEPLITE® MB10IND Purifies industrial process water by removing ionic impurities.

• Demineralization: SEPLITE® MB30IND Prevents scaling and corrosion in power plant boilers with ultra-pure water.

• Condensate Polishing: SEPLITE® MB20IND Removes contaminants from steam cycles in power generation.

• Potable Water: SEPLITE® SA400MB Ensures safe, high-quality drinking water free of dissolved solids.

• Ultra-Pure Water: SEPLITE® Monojet™ MB610U Produces water with resistivity >18.2 MΩ·cm for semiconductor manufacturing.

• Power Generation: SEPLITE® MB30IND is used in demineralization systems to produce boiler feedwater, preventing scale buildup and extending equipment life.

• Pharmaceuticals: SEPLITE® SA400MB ensures water purity for drug formulation, meeting stringent regulatory requirements.

• Semiconductor Manufacturing: SEPLITE® Monojet™ MB610U delivers ultra-pure water to prevent contamination in electronic component production.

• Food and Beverage: SEPLITE® resins maintain water quality for consistent taste and extended product shelf life.

• Case Example: In a recent power plant project, SEPLITE® MB10IND reduced water conductivity to <0.1 µS/cm, improving turbine efficiency and reducing maintenance downtime by 20%.
