PolyFloc* Flocculants
High Molecular Weight Clarification and Dewatering Polymers
 Cost-effective Liquids and Powders
 Wide portfolio of clarification and dewatering
aids (flocculants)
 NPE-free products
 Range of molecular weights and charge (anionic,
non-ionic and cationic)
Description and Use
PolyFloc products are high molecular weight water-
soluble polymers. They are designed to function in a
variety of industrial water and wastewater treat-
ment applications. Depending on customer prefer-
ence they are available in concentrated powder
form, cost-effective emulsion liquids and conven-
ient, easy-to-feed liquid solutions.
In solids separation treatment programs, polymers
are used as “coagulants” for charge-neutralization
of colloidal particles, and as “flocculants” for ag-
glomeration of particles into larger particles or
“floc”. GE’s KlarAid* product line encompasses the
coagulants. The PolyFloc product line are floccu-
lants designed to bridge small particles together,
enhancing floc formation. This increases settling
velocity in clarification, or rise-rate in flotation ap-
plications, and improves water drainage in thicken-
ing and dewatering applications.
Products and Services Offered
The PolyFloc product line encompasses a compre-
hensive portfolio of charge type, ranging from low
to high anionic or cationic charge, thereby allowing
GE to provide products for both raw and
wastewater clarification, flotation enhancement
and sludge conditioning (for thickening and de-
watering).
The PolyFloc AE products are anionic emulsion liq-
uids; AP products are anionic powders and AS
products are the convenient solution liquids. Simi-
larly, the CE products are cationic emulsion liquids
and the CP products are cationic powders.
PolyFloc products are provided as part of a com-
prehensive treatment program by highly technical
field personnel who evaluate each customer’s spe-
cific application needs and treatment objectives,
before selecting the optimum product for that sit-
uation. Typically, on-site testing is performed to
ensure a cost-effective solution is chosen.
A PolyFloc product is applied as part of a compre-
hensive package of products, operational recom-
mendations and modern monitoring to ensure an
effective overall solution for the customer.
Application and Treatment
Proper application and treatment levels depend on
many factors and flocculant applications are specif-
ically designed for each application and for each
individual facility’s needs. However, there are some
common requirements as described next.
Apart from the solution products, the emulsion and
powder products need to be dissolved in water be-
fore use. Emulsion liquids have to be “inverted” from
the oil-phase to the water phase in a batch mix-
tank or continuous “make-down” system. Typically
the product is added to water with an appropriate
amount of mixing, to obtain a solution strength of
0.25- 0.5% product in water. Continuous-feed
equipment is available from GE to automate this
process.
Powder products are either manually batched in a
mix-tank, or automated feed systems are available
for larger applications. Recommended solution
strength is often in the same range as emulsion
