At the global level, the augmenting presence of harmful algae blooms
constitutesimportant dares to water treatment plants (WTPs). In WTPs, coagulation
remains the primary process of the applied procedure to treat
algae-contaminated water. Such a chemical process influences the following
techniques; thus, regulating coagulation parameters to eliminate algae at the
maximum degree without provoking cell deterioration is more than crucial. This
work aims to review coagulation-founded methods for algae elimination. First,
investigations concentrating on algae elimination using the chemical process
are discussed. The introduction presents the widespread algae encountered in
the water treatment field. Then, habitually utilized experimental techniques
and emerging methods in coagulation investigations are summarized with typical
findings. Next, the newest expansions in improved algae elimination, launched
by electrochemically and ultrasonically-enhanced coagulation, are discussed.
Workable thoughts for applying coagulation to eliminate algae in WTPs are also
debated. The paper finishes by defining restrictions and dares related to the
present literature and suggesting trends for subsequent studies. The charge
neutralization mechanism efficiently removes solubilized microcystins (MCs),
and enhanced coagulation configuration is also found to be more efficient for
their removal. However, considerations should be taken to avert that the acid
introduction has no unwanted effect in killing algae treatment to avoid the
solubilized MCs level elevation. If such techniques are well-optimized and
controlled, both algae and solubilized MCs could
be efficaciously removed by ultrasound-enhanced coagulation and electrocoagulation/electrooxidation.
