Phosphorous removal from wastewater - Lenntech
Ferric chloride or sulphate and ferrous sulphate also know as copperas, are all widely used for phosphorous removal, although the actual reactions are not fully understood. The basic reaction is: Fe 3+ + H n PO 4 3-n ↔ FePO 4 + nH + Ferric ions

- Can polyacrylamide aqueous dispersion be soluble after polymerization?
- However, after polymerization, the resulting copolymer should not be soluble in the dispersion medium. The first non-ionic monomer used in aqueous media was acrylamide, which can be copolymerized with anionic and cationic monomers to produce an ionic polyacrylamide aqueous dispersion system .
- Which dispersion medium is used for cationic polyacrylamide aqueous polymerization?
- Initially, most researchers utilized ammonium sulfate as the dispersion medium for polymerization. Zheng et al . prepared a stable cationic polyacrylamide aqueous dispersion using poly (2-methylacryloylxyethyl trimethylammonium chloride) (DMC) as the dispersion stabilizer and potassium persulfate-sodium sulfite as the initiator.
- What is the molecular weight of a polyacrylamide dispersed system?
- The resulting polyacrylamide dispersed system exhibited a molecular weight of up to 1.05 × 10 7 g·mol −1, indicating significant stability. Zhao et al . utilized dispersion polymerization to synthesize polyacrylamide, employing an aqueous solution of ammonium sulfate and sodium chloride as inorganic salts.
- Can hydrophobic associative polyacrylamide be polymerized by aqueous dispersion polymerization?
- Hydrophobic associative polyacrylamide synthesized by aqueous dispersion polymerization can be polymerized using cationic monomers in combination with acrylamide and hydrophobic monomers, as well as copolymerized with anionic monomers alongside acrylamide and hydrophobic monomers.
