Different water quality, different amount of sewage, there are some differences in adding
polyacrylamide dosage. Therefore, to ensure the purification effect, must be reasonable use of polyacrylamide dosage.
First, the sewage water quality and concentration
different factories of sewage water quality, concentration and polyacrylamide dosage has a great relationship, such as the same sand washing plant, sewage sediment content is different, the use of polyacrylamide amount is different, the same content of sediment, water quality in different areas and different mud will also lead to different amounts of product use. Chemical plants, pharmaceutical factories, paper mills and other industrial wastewater quality compared to the sand washing plant is much more complex, subtle changes will cause changes in the dosage.
Second, the site conditions
site conditions include the concentration of water treatment chemicals dissolved, dissolution time, coagulation time and intensity, the impact of process equipment. Dissolved concentration of high coagulation will result in increased difficulty, the amount of chemicals used is not easy to control. Short dissolution time leads to waste of chemicals and increase in the amount of use. When the coagulation time is short and the intensity is low, it is not suitable to use high molecular weight or high concentration solution products, which is easy to waste chemicals. The influence of process equipment, such as plate and frame machine than filter belt machine to save drugs, different manufacturers of equipment for water filtration performance is also a difference. Problems such as the above is just an example, the actual application of operating conditions, the impact of equipment on the use of pharmaceuticals are greatly affected.
Third, the product selection problem
polyacrylamide model determines its dosage, such as the use of anionic polyacrylamide 18 million molecular weight and anionic 8 million molecular weight, although the molecular weight is not the higher the better, but for the majority of the water quality of high molecular weight products when used properly cost-effective is still high, the two types of use in the same water quality, then the dosage is completely different, may be twice as much as the difference between the difference between the difference between the double or even more. More.
Users in the selection of polyacrylamide, must be selected by sampling experiments, and then on the machine test, to determine the exact model of polyacrylamide and dosage, in order to achieve good results, low dosage, low cost of the ideal effect.
