Issues regarding the use of polyacrylamide for phosphoric acid
Thread Content
Please discuss the specific issues related to the use of polyacrylamide as a phosphate filtration aid, such as manufacturers, concentration, water usage, and the point at which it is added.
Previously, we used one with a molecular weight of 12 million, which was evenly dispersed in a hot water tank equipped with a stirrer; after dissolution, it was added to the slurry that was to enter the filter. A certain mixing time was required after addition, and this can be adjusted slightly from a process perspective.
Our company’s improved version amounts to 16 million units; it has its own volume and is in liquid form. The usage level is 20–30 ppm. Currently, companies such as Yuntianhua Furi and Guizhou Kailin are using it. We also supply defoamers and phosphate sedimentation flocculants. Imported originally
We use the product from Shanghai Peichun; it is added before the distributor in the filter. The results are very good – the water-soluble phosphorus content in gypsum has dropped from 0.3% in the past to 0.06% at present.

We are currently using one from Sichuan University, which is installed on the pipeline leading to the filter slurry; specific adjustments need to be made based on actual production conditions, and it is generally located above the filter.
