Treatment of Pulp and Paper Mill Wastewater with Various
Treatment of Pulp and Paper Mill Wastewater with Various Molecular Weight of PolyDADMAC Induced Flocculation with Polyacrylamide in the Hybrid System. Flocculation studies between dual polymers on pulp and paper mill wastewater are reported in this paper. The effects of different molecular weights of polyDADMAC and different dosages of Polyacrylamide (PAM) were studied.
The flocculation performances of different molecular weight of polydiallyldimethylammonium chloride (polyDADMAC) in the treatment of pulp and paper mill wastewater were studied.
PolyDADMAC and polyacrylamide as a hybrid flocculation
A new kind of organic-inorganic poly (aluminum chloride)-poly (dimethyl diallyl ammonium chloride) (PAC-PDMDAAC) hybrid polymer flocculant was synthesized using ammonium persulfate as initiator
Sludge conditioned with coagulants and flocculants as a hybrid system is rarely reported; little is known about the application of the hybrid coagulation-flocculation process for sludge conditioning and dewatering .

Poly(DADMAC) also improved the flocculation ability of the composite flocculant by bridging the suspended particles. The hybrid composite flocculants with 30 and 70 wt% MgCl 2 could flocculate 2 wt% kaolin
Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 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
Article Characterization of a hybrid polyacrylamide and its flocculation properties in cyanide tailing suspensions. An inorganic-organic hybrid flocculant Al(OH)3-polyacrylamide (Al-PAM) with narrow molecular weight distribution was synthesized using...

Flocculation studies between dual polymers on pulp and paper mill wastewater are reported in this paper. The effects of different molecular weights of polyDADMAC and different dosages of Polyacrylamide (PAM) were studied. The molecular weights of polyDADMAC used were 8.8×104, 10.5×104 and 15.7×104 g/mol.
Evaluation of the Flocculation Characteristics of Polyacrylamide Grafted Xanthan Gum/Silica Hybrid Nanocomposite. Industrial & Engineering Chemistry Research 2013, 52 (29) , 9731-9740. DOI: 10.1021/ie400550m.
A Study on the Flocculation and Sedimentation of Iron
Based on the regulating behavior of Fe3+, flocculation and sedimentation tests of iron tailings slurry flocculated using 2 mg/L anionic polyacrylamide (APAM) were studied, including the tests of Fe3+ dosage, regulating time, and pH. Flocculation–sedimentation tests showed that: a recommended addition of 56 mg/L Fe3+ produced a surprisingly bad flocculation effect; sedimentation ability
The application of cationic polyacrylamide-Henan Yuanbo . Cationic polyacrylamide (CPAM) is a kind of linear organic macromolecular polymer, because it has a variety of active groups, it can bond with many substances and form hydrogen bonds.Mainly flocculation negatively charged colloid, except the turbidity, decoloring, adsorption, adhesion, and other functions, suitable for dyeing
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- What is the chemical formula of poly aluminum chloride?
- Introduction : Poly aluminum chloride referred to the PAC. It is a water soluble inorganic polymers between ALC13 and A1 (OH)3, the chemical formula is [AL2 (OH)nC1 (6-n)]m, where in m means polymerization level, n represents PAC products alkalization. The products colour is yellow, pale yellow or dark brown resinous solid.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
