Coke is an essential raw material for the steel industry. With the rapid development of the steel industry, the demand for coke is increasing, and the amount of coking wastewater is also increasing. The pollutants contained in coking wastewater include phenols, polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen and sulfur, etc., which is a typical toxic and refractory organic wastewater.
Polyacrylamide is a kind of linear polymer, with “all industry additives” said, it plays an important role in the treatment of coking wastewater.
Polyacrylamide because it has a variety of active groups, and many substances affinity, adsorption form hydrogen bonds. Mainly flocculated negatively charged colloid, with turbidity removal, decolorization, adsorption, adhesion and other functions. It plays an important role in the treatment of coking wastewater.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
