Name: Liquid Polyacrylamide (PAM)
Product standard: GB17514-2008
Models: APAM, CPAM, NPAM, ZPAM
2. Introduction of Liquid APAM
① Industrial wastewater treatment. The effect of treating sewage
which the pH is neutral or alkaline, which the suspended particles
in water are kind of big, and which is positive such as the sewage
from steel plants, electroplating factory, metallurgical plant and
coal washery is very remarkable.
② Drinking water treatment. The products, which has advantages of
small dosage, low cost and no secondary pollution, can be used for
tap-water which is high-sand-content and turbid.
③ Papermaking additive. The products can be used as dispersants,
paper-strengthening agent, retention and drainage agents for
long-fibred papermaking, also as flocculant for wastewater after

3.Introduction of Liquid CPAM
① As the flocculating agent, it not only works on treating domestic
sewage and organic sewage , such as alcohol sewage, papermaking
sewage, sewage of monosodium glutamate, sugar factory sewage, feed
sewage, printing and drying sewage and so on, but also helps with
treating on urban sewage. Also, it helps with settling sludge and
dewatering sludge during treating meat-packing sewage, poultry
processing sewage and food processing sewage.
② It works as drying strengthening agent, retention agent and
filter aid in papermaking. It also helps with treating of tail
water. Meanwhile it makes a good flocculation in the process of
③ It can work as fining agents for mine wastewater and oily
wastewater in beneficiation and coal preparation.
④ It can used for treating of dyed wastewater, leather wastewater,
and oily wastewater.
⑤ In phosphoric acid purification, it helps with gypsum separation
in process for wet-process phosphoric acid
⑥ It works as flocculation in water treatment in waterworks which
using water from rivers.
⑦ It used for chemical additives in oilfield, such as clay
anti-swelling agent, viscosifying agent.

① It should be made up to dilute solution while using alone, which
the average working concentration is 0.1%-0.3% (Solid content). It
should be dissolved by neutral and low-hardness water with no
suspended matter and inorganic salt inside.
② Customers should choose products according to treatment
technology and water conditions while treating different sewage and
sludge. Customers should base amount of agents on concentration of
treated water and moisture content of sludge.
③ Customers should choose release points and control mixing speed,
not only for pouring the solution evenly, but also for avoiding
breaking the flocculation.
④The equipment which contacts with solution should be made by
stainless steel, plastic, glass or carbon steel with resin coating.
⑤ Use it as soon as possible after making up the solution.
4.Introduction of Liquid NPAM
Non-ionic polyacrylamide which is formed by homopolymerization of
acrylamide shows nice advantages in high purity, good solubility,
high molecular weight and available pH range of 1-8.
①It is mainly used for treating sewage. Especially in acid sewage,
it works very well. It also matches well with inorganic
poly-aluminium flocculant and aluminium sulfate.
② It’s used for metallurgy and ore dressing, like
