Application of polyacrylamide flocculants for water treatment
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces
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
Synthesis of cationic polyacrylamide by low-pressure UV
Meanwhile, effective organic polymer flocculant, especially cationic polyacrylamide (CPAM), was developed and extensively used for turbidity separation because of their satisfactory solid-water separation performance . Generally, cationic polyacrylamide is copolymerized by acrylamide (AM) and cationic monomers in an aqueous solution.
Treatment of sewage sludge (SS) by biodegradable polyacrylamide-based flocculants (PAM) is considered to be an effective way to increase total solids (TS) content prior to anaerobic digestion (AD).
The Effect of the Flocculants PAM and PAC - Polyacrylamide
In the treatment of the domestic sewage, there are two types of the water flocculants: the PAM (Polyacrylamide) and the PAC (Polyaluminium Chloride).The domestic sewage is the waste water which is directly discharged by the residents in the daily life, the major component is the stool and the washing waste water.
1. Introduction. The global water crisis has become one of the most immediate threats restricting human development [, , , ].The increasing water pollution has brought unprecedented challenges to the wastewater treatment [].At present, the most commonly used organic flocculant for water treatment is polyacrylamide (PAM) [6,7].The linear ultra-high molecular weight cationic and anionic PAM are
Homogeneous synthesis and characterization
In this work, cationic cellulose (CC) with different degrees of substitution (DS) was successfully synthesized by the reaction between cellulose and 3‐chloro‐2‐hydroxypropyl‐trimethylammonium chloride (CHPTAC) in a 7 wt % NaOH and 12 wt % urea aqueous solution.
cosmetics (Yan 1998). For the same applications, high molecular weight polyacrylamide (PAM) has been widely used because of its effectiveness and low price, but it is nonionic. If a polymer has charged groups on its chain, it will be more effective as a retention aid in papermaking and as a flocculant. Hence, many cationic polymers are prepared by

PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good
Flocculation of kaolin particles with cationic lignin polymers
Among the cationic polyacrylamides that Ariffin and coworkers 42 studied in the flocculation of palm oil mill effluent, the flocculant with the molecular weight of 1.5 × 10 6 g/mol was the most
The key to coagulation treatment of printing and dyeing waste water is to select suitable flocculant. The flocculant which is conventionally suitable for printing and dyeing wastewater treatment mainly includes polyaluminium chloride, aluminum sulfate, iron sulfate, ferric chloride and cationic polyacrylamide in the later stage.
- What is poly aluminum chloride?
- In conclusion, Poly Aluminum Chloride stands as a revolutionary force in water treatment, offering a comprehensive suite of benefits that extend from coagulation and flocculation to cost-effective and environmentally conscious solutions.
- What is poly aluminum chloride (PAC)?
- Poly Aluminum Chloride (PAC) has emerged as a game-changer in the realm of water treatment, redefining the landscape with its multifaceted benefits.
- What is aluminum chloride hydroxide?
- Aluminum chloride hydroxide, AlCl (OH) 2, AlCl 2 (OH), products, commonly known as polyaluminum chlorides (PAC), are used for a wide variety of industrial applications. Other names for PAC are basic aluminum chloride, polybasic aluminum chloride, aluminum hydroxychloride, aluminum oxychloride, and aluminum chlorohydrate.
