ColorSorb sorbents

ColorSorb has the highest capacity of commercial sorbents for the removal of negatively charged tannic and humic compounds that act as pre-cursors for trihalomethane (THM) formation. ColorSorb media can effectively remove 80% or more of these contaminants based on actual field and laboratory tests. The brown and yellow color associated with humic an fulvic acids is significantly reduced, particularly when ColorSorb is placed ahead of ion exchange resins, membranes or activated carbon. The introduction of chlorine into waters containing humic an fulvic substances tends to break down these large molecules and form THM pre-cursors. It is recommended that ColorSorb media be used ahead of chlorination treatment for optimum removal of these contaminants.
