HEDP is an organophosphorus acid scale and corrosion inhibitor that can form stable complexes with iron, copper, zinc, and other metal ions that can dissolve the metal surface oxides. It is a scale inhibitor and corrosion inhibitor for boilers and heat exchangers, complexing agent for cyanide-free plating, soap chelating agent, and cleaning agent for metal and non-metal.
Aluminum hydroxide chloride ach is a highly polymerized solution of aluminum polymer chloride. The highly polymerized aluminum in ACH has a higher cationic charge than standard salts such as alum or PCA, or even other aluminum salt products. Compared to traditional metal salts and low alkalinity AlPCs, ACH coagulates effectively over a wider pH range (e.g., 5-95).
Acrylamide emulsions are prepared by dispersion or reverse-phase emulsion polymerization and are a form of polyacrylamide liquid. In addition to the properties of solid polyacrylamide flocculants, suspended solids in water particles are adsorbed by polar groups on the molecular chain, and emulsions can form large flocs by cross-bridging between particles or electrically.
Polyacrylamide (PAM) is a polymer formed from acrylamide units, and acrylamide is a known neurotoxin. However, according to Wikipedia, polyacrylamide is not considered toxic but is a controversial ingredient due to its potential ability to secrete acrylamide. It is used in cosmetics and beauty products in two different forms, a highly absorbent soft gel in a cross-linked form and a thickener and suspension agent in a straight-chain form. Recently, it has also been used as an active ingredient in the dermal wrinkle filler Aquamid.
Coal washing wastewater is the wastewater produced in the wet process of coal washing in coal mines, containing a large amount of slurry and silt.
The global polyacrylamide market is expected to grow significantly in the coming years due to increased wastewater management awareness.
