Another advantage is avoiding undesired microbial growth due to after initial use, presence of heavy metals adsorbed in the organic material will
inhibits or reduce the microbial growth. Potential for metal recovery
is another advantage of the technology since when the system
is saturated, it is possible to separate the organic material from
metals by incineration and reuse metals for other applications. Another
possibility, because the heavy metals are bound to organic
matter through ionic bonds, they can be recovered simply by
changing the pH of the column and allowing its separation from
the biosorbent.
