The application of tannins in water treatment mainly includes the following aspects:
Wastewater treatment flocculant: Tannin extract can be used as a flocculant for wastewater treatment. Studies have shown that flocculants made from wattle bark tannins modified through aminomethylation can significantly improve the treatment effect of tannery wastewater and increase the COD removal rate.
Boiler water softener: As a good boiler water softener, tannin extract has the characteristics of easy use, low cost and good effect. It can both remove and prevent scale, and is suitable for the treatment of clean water and polluted water.
Desulfurizer: Tannin extract is widely used in gas desulfurization and purification. The research and development of tannin method desulfurization began in the 1980s. The new desulfurization catalyst used for gas desulfurization purification stabilizes the production process and improves economic benefits. The composite tannin desulfurization catalyst is a major improvement in tannin method desulfurization. It has the advantages of high desulfurization efficiency, low production cost and good production stability.
