Acid treatment technology for foil industry

Product Description

In the process of foil corrosion, a large amount of waste acid is produced. The discharge of these waste acids (even if neutralized by lime) not only causes a waste of resources, increases the cost of products, but also leads to serious environmental pollution, affecting and restricting the survival and development of enterprises. Taking a medium-sized low-voltage electrode foil production enterprise as an example, it emits 15-20% of 30 tons of waste hydrochloric acid every day, which is equivalent to wasting 15-20 tons of 31% of finished acid. Using diffusion dialysis technology, the hydrochloric acid can be effectively recovered, and the economic benefits generated by saving hydrochloric acid are more than 200,000 yuan per month, while also solving the environmental pollution problem, and the economic and social benefits are very good.
