They are fluid form and liquid grade
polyelectrolytes and used for the same purpose
with powder grade cationic polyelectrolytes.
They can perform at the field both better or
worse in comparison with different wastewater
characters  due to differences of
copolymerization technics and polymer chain
structure eventough both form has the same
cationicity and equivalent molecular weight
values. Liquid grade cationic polyelectrolytes
are not only used as they supplied but also
applicable as soluted in water. In comparison
with powder grade cationic polyelectrolytes ,
liquid grade ones are more advantagous in terms
of solution preparation time required.
This is a liquid organic cationic polymer used
to remove oil and suspended soilds from water.
It can be used alone or together with coagulants
and flocculants such as iron salts, etc. It is
suitable for use in air flotation separation,
gravity settling and direct filtration. When
used in conjunction with standards flocculants,
it produces an excellent flock in treatment.
