If the mud content in the sand used for construction is too high, it will lead to a decrease in the strength of the concrete during use. Therefore, sand washing is needed to remove the mud content in the sand during the sand making process, which requires a large amount of water and generates a large amount of sand washing wastewater. If directly discharged, it will not only pollute the surrounding water quality environment but also increase the cost of sand washing water. Polyacrylamide is a high molecular weight linear polymer with excellent adsorption and flocculation effects. Polyacrylamide used for sand washing can quickly coagulate and precipitate impurities such as soil in the sand washing wastewater. After treatment, the sand washing wastewater can be clarified to meet discharge standards or recycled. This not only does not pollute the environment but also saves water consumption during the sand washing process, thereby reducing sand washing costs.
Due to the differences in water quality, raw materials, and production environments in different regions during the sand washing process, the quality of the sand washing wastewater produced also varies. When choosing which type of polyacrylamide to use for sand washing, we usually determine it through water sample testing of the sand washing wastewater. This can select the appropriate specification of polyacrylamide for sand washing and improve the effectiveness of wastewater treatment. SECCO Environmental Protection has its own wastewater sample laboratory. If you are unsure about which specification of polyacrylamide to use, you can send the water sample by mail and we will test it for free to select the appropriate polyacrylamide specification for sand washing.
