Polyacrylamide is diluted before use and then added. Generally, it needs to be compared before use. Take a certain amount of polyacrylamide and add it to clear water. Tap water should be used instead of alkaline and acidic water. The dissolution ratio is 0.1%-0.5%. After stirring and dissolving, the agent is fully dissolved in water, and the water looks completely transparent, so it can be put into sewage for use.Since polyacrylamide is a chemical, professional equipment should be used to avoid its reaction with other chemicals.Generally, gravity dosing and pressure dosing are used. The dosing needs to be based on the amount of sewage. The dosing amount is small, the flocculation effect is not obvious, and the effect will be weakened. If the dosing amount is large, the water will become viscous and it is easy to clog filters and pipelines. It is essential to master the dosing time and dosage during the dosing period. Proportional dosing can save costs and the effect will be better.

On the other hand, polyacrylamide solution, diluted solution should be used as much as possible on the same day. If it is put for too long, it is easy to cause poor effect and secondary waste.The dose is divided into two or more doses and some are put into the water. After each dose, mix it with the water quickly, and then immediately participate in the other dose, and then mix it with the water quickly.
