can be considered
as a novel relevant technology to overcome the drawbacks associated
with conventional wetland processes in terms of choking,
clogging, slow mass transfer, and poor root penetration into the
multilayer soil column (Valipour et al., 2009). This practice provides
a desirable condition for plant root growth, efficient oxygen diffusion,
and a distinguished surface area for microbial colonization in
the system. The interrelationships between plants and microorganisms
associated with biofilms attached to the support matrix,
stems, roots and water column form a high rate phytoremediation
system. The selection of an appropriate type of vegetation plays a
very important role when designing the phytoremediation with
attached growth system. Depending on the plant species, plant
effects have a strong influence on the performance of treatment on
the basis of microbial activity and their population by providing
attachment sites through roots and stems, uptake capability and
releasing oxygen. Therefore, the application of this technique can
be one of the challenging and worth pursuing in order to achieve
high treatment performance.
