1. Introduction
Food sewage treatment refers to the treatment of the food processing wastewater generated, and the pollutants in it are removed or reduced to meet the environmental discharge standards and protect the environment. Polyacrylamide (PAM) is a polymer compound that is often used as a flocculant in food wastewater treatment.
Second, the role of polyacrylamide in food sewage treatment
Food sewage contains a large amount of suspended solids and organic matter, and direct discharge will cause pollution to the environment. Treatment with polyacrylamide aggregates suspended solids and organics into larger particles, which facilitate subsequent precipitation and filtration. Polyacrylamide also has good hydrolysis resistance and thermal stability, which can play a long-term flocculation effect in the treatment of food processing wastewater.
3. The use of polyacrylamide for food sewage treatment
The use of polyacrylamide in food wastewater treatment needs to be dosed in a certain proportion. In general, depending on the concentration and water quality of the wastewater, a small test can be carried out to determine the optimal dosing ratio. Then, calculate the amount of polyacrylamide needed according to the actual treatment capacity and dissolve it in an appropriate amount of water to form about 01-0.5% polyacrylamide solution. Finally, the solution is evenly put into the food sewage treatment tank for flocculation.
Fourth, the sales of polyacrylamide for food sewage treatment
Polyacrylamide for food wastewater treatment is a specialty chemical that is usually produced and sold by specialty chemical companies. There are several companies in the market that provide sales services for polyacrylamide for food wastewater treatment, and you can choose the right product according to your needs. Here are some common food wastewater treatment polyacrylamide sellers and their product features::
The above sellers are only examples, and there are more ** merchants to choose from in the actual market.
5. Summary
Polyacrylamide for food wastewater treatment plays an important role in the food industry, which can effectively treat food processing wastewater and protect environmental safety. To purchase polyacrylamide for food sewage treatment, you need to choose a reliable supplier and choose a suitable product according to actual needs. At the same time, the use of polyacrylamide for food wastewater treatment needs to be dosing according to the correct method to ensure the treatment effect. With the right use and the right products, the goal of food wastewater treatment can be better achieved.
