Activated
sludge is the most commonly used biological process for wastewater treatment.
Normal practice in wastewater treatment plants is to employ the use of synthetic polymers for enhancement of sludge settling. These synthetic polymers
have many disadvantages; they are expensive, toxic and can pollute the
environment.

Thus, high flocculation potential, low cost, environment friendly
and sustainable biopolymers (e.g., chitosan, sodium alginate and microbial
flocculants) are being searched by many researchers. Extracellular polymeric
substances (EPSs) are of considerable importance in the removal of pollutants
from wastewater, in bioflocculation and settling and in the dewatering of
activated sludge. EPSs are located outside the cell surface and can be
subdivided into bound and soluble EPSs. Read More>>>>>>>>
