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 water­soluble polymers. They are designed to function in a
variety of industrial water and wastewater treat­ment applications. Depending on customer prefer­ence they are available in concentrated powder
form, cost-effective emulsion liquids and conven­ient, 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 floccu­lants designed to bridge small particles together,
enhancing floc formation. This increases settling
velocity in clarification, or rise-rate in flotation ap­plications, and improves water drainage in thicken­ing and dewatering applications.

Products and Services Offered

The PolyFloc product line encompasses a compre­hensive 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 de­watering).

The PolyFloc AE products are anionic emulsion liq­uids; AP products are anionic powders and AS
products are the convenient solution liquids. Simi­larly, the CE products are cationic emulsion liquids
and the CP products are cationic powders.

PolyFloc products are provided as part of a com­prehensive treatment program by highly technical
field personnel who evaluate each customer’s spe­cific application needs and treatment objectives,
before selecting the optimum product for that sit­uation. Typically, on-site testing is performed to
ensure a cost-effective solution is chosen.

A PolyFloc product is applied as part of a compre­hensive package of products, operational recom­mendations 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 specif­ically 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 mix­tank 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

products, but regardless of product, GE field repre­sentatives will provide “make-down” recommenda­tions tailored to each application. More details are
also provided in the individual product fact sheets.

Diluted product may be fed by a pump or by gravity
flow to a point where good mixing, but not violent
agitation, with the waste stream occurs. Sludge
thickening and dewatering applications require
careful engineering of feed systems and will be op­timized for each location by GE field engineers. Typ­ically, flocculant applications require careful
consideration of mixing conditions.

Storage, Handling and Safety instructions are pro­vided with every product in the form of written rec­ommendations and detailed MSDS.

Solution Benefits

GE’s PolyFloc products, used together with an in­depth system audit, engineered application and
operational recommendations will provide one or
more of the following benefits:

 Cost-effective clarification and flotation opera-

tions for improved effluent quality

 Cost-effective thickening and dewatering appli-

cations for increased sludge solids content
(minimal water content)

 ISO certified quality products
 GE technical expertise in optimizing operation of

process unit

 GE assistance in monitoring performance of

process unit

 Meeting environmental regulations reliably
 Compliance with all Health and Safety require-

ments with GE support and documentation

 Ability to adapt to changing water, wastewater

and sludge quality, due to access to wide port­folio of GE products. GE on-site service will pro­vide product selection and operational advice
as needed.

 Delivery and Billing options to meet almost any

customer need.
