Selective Ion Exchange for Heavy Metal Removal and Ultra-Pure Water
The ALMA ION selectively removes dissolved cations or anions from water and wastewater. Depending on the application, selective ion-exchange resins, cation and anion exchangers, or mixed-bed resins are used. This makes the system suitable both for heavy metal removal and recycling, as well as for use as a polishing stage for deionized and ultrapure water.
Dissolved ions in water
Pre-treated wastewater, process water, or RO permeate flows through the pressure vessel filled with ion-exchange resin .
Selectively bind target ions
Functional groups on the resin bind unwanted cations or anions and, in return, release other ions into the water in a controlled manner.
Restore Storage Capacity
Once the loading limit has been reached, the resin is treated with suitable regenerants, or the DI cartridge is replaced through the regeneration service.
Typical Applications of the ALMA ION
- Selective Heavy Metal Removal Removal of dissolved metal ions such as nickel, copper, or lead from suitable industrial wastewater streams.
- Polishing after Precipitation and Filtration Separation of remaining dissolved metal ions, which were not completely removed by chemical precipitation.
- Process and Rinse Water Circuits Continuous treatment of contaminated partial streams for recirculation into industrial processes.
- Production of Deionized and Ultrapure Water Reduction of residual ions following a reverse osmosis process or as a standalone polishing stage.
- Boiler feedwater and process water Achieving low and stable conductivity for quality-critical applications.
What determines the interpretation?
- Type and Concentration of Ions The selection of the resin depends on the target ions, co-ions, concentrations, and the desired process quality.
- Selectivity of the Ion Exchange Resin Different resins have different affinities for heavy metals, hardness-causing substances, acid residues, and other ions.
- Water Pretreatment Particles, oils, organic contaminants, and oxidizing agents should be sufficiently reduced before ion exchange.
- Loading and Breakthrough The system is designed so that ion breakthrough is detected in a timely manner and the required water quality is reliably maintained.
- Regeneration and Wastewater Management Plan Regenerant, rinse water, and the resulting concentrate are already taken into account during system design.
