Treatment and application of wastewater from hot dip galvanizing plant

Hot dip galvanizing has a broad development prospect, it has low cost, simple operation, this technology is used by many steel mills. The hot dip galvanizing factory will produce some sewage in the production process, which is mainly divided into acidic sewage and alkaline sewage. These sewage will pollute our living environment. What should we do with it in the process of production?

These acidic and alkaline wastewater is usually produced in the pretreatment section of zinc plating. Neutralize it with an acid and a base, and get its PH up to a standard discharge. But we have to think about the cost, we have to choose the right medicine to minimize the cost. This is a common sewage treatment.

Because the mixed acid and alkaline wastewater is acidic, the concentration of these waste acids is very high, some of them even higher than that of pickling. It is not only a waste of resources but also a pollution to the environment. In order to save the environment, these acid solutions will be recycled and reused. This is both environmentally friendly and economical, and this method is for acid suppliers to recycle.

If the waste water of hot dip galvanizing plant is recycled by acid suppliers, it is time-consuming and labor-intensive. We can use the waste acid recycling equipment to carry out acid treatment by ourselves. If you need waste acid treatment equipment, it is recommended that you consider hebei annuo, hebei annuo is committed to building a national first-class hot dip galvanizing lines supplier, deeply loved by new and old customers!
