Product description
Heavy metal removal ion exchange resin is a weak acid cation exchange media designed for the removal of heavy metals and alkaline earth metals from water. The resin is commonly used in potable water treatment and selected wastewater applications where dissolved toxic metals must be reduced. Due to its high selectivity for metal ions, this resin enables efficient removal of heavy metals while also providing softening capabilities without the use of sodium-based regeneration chemicals.Technical overview
This high purity weak acid cation exchange resin is designed to remove dissolved heavy metals from water through selective ion exchange. The resin structure allows rapid uptake of metal ions even at relatively short contact times, making it suitable for use in compact treatment vessels or cartridge systems. Unlike conventional softening resins, this resin is typically used as a disposable treatment media and is not designed for chemical regeneration.Operating principle
Heavy metal removal resin operates through ion exchange, where dissolved metal ions in the water are exchanged with hydrogen ions bound to the resin structure. As water flows through the resin bed, heavy metals such as lead, copper, and other toxic metal ions are selectively captured by the resin. This process reduces the concentration of dissolved contaminants in the treated water. Once the exchange capacity of the resin is exhausted, the media must be replaced rather than regenerated.Material options
Typical product composition includes:- Weak acid cation exchange resin
- High purity ion exchange media
- Hydrogen form resin structure
Available micron ratings
Ion exchange resin does not provide filtration based on micron ratings. Water treatment performance is defined by ion exchange capacity and the resin’s affinity for specific dissolved metal ions. Performance depends on:- Feedwater composition
- Contact time with the resin bed
- Flow rate through the treatment system
- Resin volume installed in the vessel
Design and construction
The resin consists of a porous polymer bead structure designed to maximise ion exchange surface area and ensure efficient contaminant removal. Typical product characteristics include:- Weak acid cation exchange resin
- High selectivity for heavy metals
- Rapid ion uptake in short contact times
- Suitable for potable water treatment
- Designed for use in refillable vessels or cartridges
- Non-regenerable treatment media
