Organics and nutrients removal by coagulation-flocculation process using polyaluminiumferric chloride and its aids, applied to a combined sewage in Shanghai, were studied. Cationic polyacrylamide (PAM), polyvinyl alcohol (PVA), a new type of polyelectrolyte (AN) and activated silica (AS) were used as coagulant aids.

In this study, we treated the CNFs with polyethyleneimine (PEI), polydiallyldimethyl ammonium chloride (P-DADMAC), and cationic polyacrylamide (C-PAM), and the zeta potential of the CNFs was
All polymers used in this study are water soluble which are produced by SNF Floerger, France. The nonionic polyacrylamide (P 100) is a homopolymer made up of acrylamide (Figure 1(a)).The anionic polyacrylamides (AN) are copolymers of acrylamide (Figure 1(a)) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) (Figure 1(b)) with different AMPS contents (i.e., charge density) and molecular weight.

- Who manufactures polyaluminum chloride?
- USALCO ® has manufactured chemicals for over 60 years, and began full scale production of the patented process for manufacturing Polyaluminum Chloride in 1996. Learn more about the origin of USALCO’s premier DelPAC coagulant. USALCO ® manufactures a variety of Polyaluminum Chlorides to meet a wide range of water quality objectives.
- What is polyaluminum chloride PAC?
- Polyaluminum chloride PAC is a widely used chemical compound that finds its application in various industries, primarily for water treatment. In this blog post, we will delve into the different grades of PAC, the production methods, and its specific uses in different sectors.
- What alumina content is suitable for sewage treatment?
- Typically, PAC with alumina content below 26% is suitable for urban domestic sewage treatment and municipal sewage treatment with low turbidity. On the other hand, the 28% industrial-grade PAC is ideal for industrial wastewater treatment.
- What is the molecular formula of poly-aluminum chloride?
- One of the major pre-polymerized coagulants, poly-aluminum chloride (PACl) is used broadly for water and wastewater treatment. PACl contains different amounts of hydroxyl, and the molecular formula of PACl is [Al m (OH) n (H 2 O) x ]·Cl 3m−n ( n ≤ 3 m ).
