REMOVAL OF HEAVY METALS
Our adsorbent products designed for removing soluble metals effectively remove harmful free ions from the water. The removal efficacy can be adjusted by altering the adsorbent dosage and the retention time. See the
existing environmental quality standards valid in Finland from e.g. Finlex:
The products can also be used for improving the efficiency of soluble metals removal with regular hydroxide precipitation (lime milk precipitation).
The advantage of the adsorbents manufactured by Aquaminerals is that they work in a wide pH range. As such, there is no need for separate pH adjustment. In addition, the saturated adsorbent deposits are stable and do not dissolve.
REMOVAL OF AMMONIACAL NITROGEN
Aquaminerals’ nitrogen removers work in cold waters as well, and it is not interfered by heavy metals.
Nitrogen-specific adsorbent products can be regenerated, and they work without organic matter (in comparison to biological purification).
