Hydrophobic modification of cationic microblocked polyacrylamide and its enhanced flocculation performance for oily wastewater - Springer
This work develops a novel amphiphilic polyacrylamide TP-ADL with cationic microblock structure through a UV-light-initiating template copolymerization technology. The related copolymerization factors were well optimized towards a higher
The thermal decomposition behavior of polyacrylamide poly (methacryloyloxyethyl trimethylammonium chloride-acrylamide) (P(DMC-AM)) was studied by means of TG and DSC under nitrogen atmosphere at temperature range of 323.15–823.15 K. The effect
Cationic Polyacrylamide: Synthesis and Application in Sludge Dewatering Treatment - ResearchGate
Abstract. Cationic polyacrylamide (CPAM) were used extensively in water treatment, enhanced oil recovery and sludge dewatering. The review summarized the synthesis methods research progress of
Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the
Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe | Full Text
Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is
A water-soluble cationic copolymer dispersion was prepared by the polymerization of the cationic monomer (2-methacryloyloxyethyl)trimethyl ammonium chloride and acrylamide initiated with 60Co γ-rays.
Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for wa
Where C + and A – stands for the ions (salinity as dissociated form), while H + and OH – will join to form water (H 2 O). The exhausted resins can be regenerated, meaning to re-build the original form, according to the aforementioned reactions.

1.1.1. Basic principle of coagulation: Coagulation comes from the latin word ˙ coagulare ¨ which means ˙ to agglomerate ¨. In water treatment, coagulation is the result of the addition of chemical reagents to water suspensions where the
Tetrakis Hydroxymethyl Phosphonium Sulphate (THPS) Use Guide 2025 Tetrakis hydroxymethyl phosphonium sulphate is an environmentally friendly biocide. It is mainly used in water treatment systems, oil drilling operations and the paper industry.
Glyoxalated Polyacrylamides G-PAM: additives for enhancing the strength of paper. Giovanna Pellegrini RQ, Axchem® Italia -Stéphan Lafrenière
Summary: Glyoxalated polyacrylamides (G- PAM) provide an alternative chemistry to other papermaking resins additives for wet and dry strength. This new generation of G-PAM provides a better compromise between wet end chemistry performance and
If the enhanced flocculant BTA contained bentonite, cationic polyacrylamide was more apt to adsorb and bridge with bentonite while anionic polyacrylamide will not react with bentonite obviously. It was also found that only small amount of CPAM
- What are the different types of polyacrylamide water treatment?
- Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- What are the different types of polyacrylamide (PAM)?
- So PAM chemical can be used for petroleum exploration, water treatment, textile, papermaking, mineral processing, medicine, agriculture and other industries, etc. The polyacrylamide (PAM) can be divided into four types, they are anionic PAM, cationic PAM, nonionic and amphoteric PAM. The following are their detailed introduction and specifications.
- Why is polyacrylamide used in water treatment?
- With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
