Decription of Cationic PAM (Polyacrylamide)
/ Cationic Polyelectrolyte
Cationic Polyacrylamide (CPAM) is a linear
polymeric compound, because it has a variety of lively
groups, affinity, adsorption and many substances
forming hydrogen bonds. Mainly flocculation of
negatively charged colloidal, turbidity, bleaching,
adsorption, glue and other functions, for dyeing,
paper, food, construction, metallurgy, mineral
processing, coal, oil, and aquatic product processing
and fermentation industries of organic colloids with
higher levels of wastewater treatment, especially for
urban sewage, sewage sludge, paper mill sludge and
industrial sludge dewatering process.
Cationic Polyacrylamide (CPAM) product features
1, water soluble, and can also dissolve completely in
cold water.
2, add a small amount of anionic Polyacrylamide
products, you can receive a lot of flocculation
effect. Just add 0.01~10ppm (0.01~10G/m3), to fully
play its role.
3, while using the products and inorganic anion
Polyacrylamide flocculant (polymerized ferric sulfate,
polyaluminum chloride, iron salts, etc), you can
display a greater effect.
Function Cationic Polyacrylamide, because it
has:
1 purifying, clarifying roles;
2, subsidence promoter action;
3, filtration promoter action;
4, thickening effect and its effects. In wastewater
treatment, sludge dewatering, dressing, washing,
papermaking and so on, can fully meet the various
requirements in the field
Package and storage
This product is non-toxic, moisture, rain, avoid sun
exposure. Storage period: 2 years, 25/10kg paper bag
(lined with plastic bags to stick the plastic paper
bags outside).
Application in wastewater treatment Cationic
Polyacrylamide
1. Often use powdered organic wastewater of cationic
Polyacrylamide: is usually suspended in wastewater
sewage flocculation and sedimentation of particles
with a negative charge. Based on cationic flocculation
unit in acidic or alkaline media, relying on the
positive electricity is extremely effective for rapid
clarification of sewage. In addition to powdery
Polyacrylamide, poly-aluminium chloride and anionic
Polyacrylamide is being increasingly broad application
in organic wastewater.
2. Alcohol factory wastewater, beer factory
wastewater, MSG factory wastewater, sugar factory
wastewater, meat products factory wastewater, beverage
factory wastewater, textile dyeing factory and various
sewage factory of engineering processing of wastewater
in the, contains various organic solvent, and
inorganic and the organic sulfide, and hydrocarbon
class, and chlorine, and oil, and mercury and he on
environment harmful of components, can with
polypropylene n amine for flocculation coagulation
yihou then emissions. Can also be used as slurry
treatment agent in oilfield development process,
selective plugging agent, thickening agent injection,
textile printing and dyeing process of softening
agent, Antistatic agent and common sterilization,
disinfectants, etc.
3. Used for water purification, water/oil emulsion,
oil-containing wastewater treatment, recycling of
waste water and sludge dewatering; Pam can effectively
reduce the friction of the fluid, trace Polyacrylamide
can include water resistance 50-80%
Cationic Polyacrylamide using processes:
1, granular Polyacrylamide flocculant agent cannot
directly in addition to sewage. It must first be
dissolved in water before use, using its aqueous
solution to wastewater treatment.
2 water should be clean, dissolving granular polymer
(such as water), and cannot be a sewage.Water at room
temperature, typically do not require heating.Water
temperatures below 5 ° c are dissolved very
slowly.Dissolved water temperature increase faster,
but more than 40 ° c causes the accelerated
degradation of polymers, effect using the effect.Tap
water is suitable for the preparation of polymer
solution in General.Strong acid, alkali, salt-laden
water is not fit for the preparation.
3, selection of polymer solution concentration,
company recommends to 0.1% per cent, that is, 1 liter
of water and 1g-3G in polymer powder. PAM
concentration options to take into account the
following factors: Preparation tank is small and large
amount of medication every day, proposed grading of
slightly dense (such as 0.3%). Polymer molecular
weight is high, slightly dilute some of the proposed
distribution (such as 0.1%). In polymer solutions into
the sewage, such as dispersed when the situation is
not very good for equipment reasons, recommends
slightly dilute some of the distribution. In short,
polymer concentration too large will cause agitator
motor load is too large, can also cause after entering
the water dispersing condition is not good, affect the
results. Worthy of dilute some help to increase the
effect.
4.Centrifugal pumps for distribution with a solution
do not transfer, so as to avoid high speed rotating
blades caused shear of polymer degradation.
Preparation of specific methods are as follows:
Solution (such as lab beakers, preparation of plant
pot) by adding a certain amount of water, water volume
and concentration calculate the required amount of
powdered polymers, polymer.
