Qualfloc™ PAM Flocculants for Wastewater
Treatment
The Qualfloc™ PAM polymer flocculants and coagulants are used
extensively in wastewater treatment for municipal and industrial wastewater
treatment plants.
Municipal Wastewater Treatment
Our products can be used in all solid-liquid separation processes in
municipal (or sewage) wastewater treatment:
·
Primary
sewage treatment. Usually the use of an anionic polymer in combination with an inorganic/organic
coagulant can reduce the biological loading. The size of the clarifier can be
reduced due to the accelerated settlement rates in the primary clarifiers,
resulting in a significant capital saving. Recommended Products: Qualfoc™ A2424, A3226
·
Activated
sludge treatment. Product type can vary based on the actually application
condition, however a medium to high charged cationic polymer is typically
required.
·
Digested
sludge treatment. High cationic charged polymers with wide range
molecular weight options are typically more effective for such treatment.
Industrial
Wastewater Treatment
The Qualfoc™ polymers and coagulants are extensively used
in the treatment of processing water and wastewaters for many industries:

Qualfloc™ polymers have extensive product options to fit various
application cases for all water and wastewater treatments. However it is
normally very hard to give simple recommendations mostly because the uncertain
and complicated conditions of the water being treated. In order to select the
product that has the best performance, a lab test and followed by a plant trial
test is normally necessary.
In general, if the wastewater has been biologically treated which
is likely the case in most industrial wastewater treatment plants, then the use
of a single cationic flocculants will normally give
the desired results. If the wastewater has particular high levels of BOD, COD,
oils or color, then some type of pre-treatment may well be required. It is
often the case that two or three more products will need to be combined for
complicated conditions, particularly when the substrate is difficult to
flocculate and a pre-treatment with a coagulant (may also involve PH
adjustment) is required.
For sludge dewatering, a single cationic flocculants product
will normally be the optimum product require. For wastewater color removal of
most dyeing and printing industries, Qualfloc™ 301, 302 combined with a coagulant and
flocculants is normally the product to be used. Due to the complexity of the
water, a lab test and a plant trial test for such application is normally
necessary.
