In the late period of petroleum exploration and development, drilling waste liquid is a special industrial waste water produced in the process of drilling operations, containing oil, heavy metal salt, refractory organic matter, sediment, bacteria and other toxic and harmful substances, with complexity, change, dispersion and other characteristics, it is black brown opaque colloid state, with strong pungent smell and putrid smell.
Because the seepage, overflow and submergence of oil drilling wastewater may cause the pollution of groundwater and surface water, it is necessary to conduct certain standard treatment of oil drilling wastewater before discharge.
Secco polyacrylamide is an important synthetic organic polymer flocculant. Compared with traditional inorganic flocculants, polyacrylamide has the advantages of more varieties, higher flocculation efficiency and less sludge generation.
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
