The petroleum grade PAC commonly used in the chemical industry depends on the diversity of wastewater in the chemical industry. Let's understand the characteristics of wastewater in the chemical industry and master the treatment technology. According to the characteristics of each type of sewage, the required price of petroleum grade PAC is not necessarily the same, and petroleum-grade polyanionic cellulose (PAC) manufacturers usually recommend to determine the price through experiments.
1. First of all, what we need to understand is that the chemical industry includes two categories: organic chemicals and inorganic chemicals. Chemical products are diverse and complex in composition. The waste water discharged from chemical plants is called chemical waste water.
2. Secondly, there are many kinds of chemical wastewater, most of which are highly toxic, difficult to purify, having a certain accumulation effect in organisms and obvious oxygen-consuming properties in water bodies, which are easy to deteriorate water quality. The water quality has complex components and many by-products. The reaction raw materials are often solvent substances or cyclic compounds, which increases the difficulty of wastewater treatment; the high content of pollutants in wastewater is caused by the incomplete reaction of raw materials and the entry of a large amount of solvent media used in raw materials or production into the wastewater system.
3. In the end, our technicians from Jining Fortune Biotech Co.,Ltd. find through experiments that if Fortune 28% polyanionic cellulose (PAC) is used to adjust the ph to about 8, the single-agent treatment of chemical plant wastewater has the best effect. 28% petroleum-grade polyanionic cellulose (PAC) not only has a strong coagulation and turbidity removal effect, but also has obvious decolorization and humus removal effects. To achieve the best flocculation under the same treatment conditions, the dosage of polyaluminum required is reduced by two-thirds compared with traditional aluminum salts. Under the same dosage conditions, the use of polyaluminum can obtain lower residual turbidity than traditional aluminum salts, so the same treatment results can be obtained with a lower dosage.
