Biosorption incorporating bacterial cells is
currently considered as a
viable alternative to conventional treatment methods for eliminating heavy
metal ions. Despite of various ways to commercialize biosorption in
wastewater treatment plants have been attempted, it has become a
challenging process to displace well-known treatment techniques.
Biosorption of heavy metals is considered to be one of the effective methods
for wastewater treatment developed within the advances in biotechnology,
however there are still some gaps that is needed
to be improved before
implementing in large-scale processes. One of them is application of different
design models for the optimization of process parameters such as biomass
dose, pH, temperature etc. which requires more comprehensive and
statistical assessments for both mono and multi-metal effluents. Biosorbent
recovery and reuse without decreasing sorption efficiency is another topic
that requires further assessments for practical uses and currently it is
incorporated in the majority of new biosorption studies. In the future, the
situation is expected to change as the more research is done on biosorption
technique for pilot-size applications which is more advantageous, efficient,
and desirable than currently utilized conventional technologies.
