Cylindrospermopsin (CYN) is an emerging
cyanobacterial toxin whose detection frequency is
increasing in water bodies worldwide. Coupled with
the changing climate the world is facing, the likelihood
of CYN entering water treatment plants is increasing.
Results from this study indicate that the combination
of powdered activated carbon (PAC) and chlorination
can provide a multibarrier treatment approach for the
mitigation of CYN, provided both treatment options
are optimized. The dosing of PAC is subjective in most
water treatment plants because of the high costs associated
with its application. However, the model developed
by the authors will aid in the derivation of a PAC
dose table that can be used to optimize PAC application
for CYN removal and significantly reduce capital
costs by reducing the amount of PAC that is wasted
through overdosing. Water suppliers will be able to use
the approaches described in this article to optimize the
application of PAC and chlorine in their water treatment
plants to remove CYN. Includes 42 references, tables, figures.
