In open type hot dip galvanization we use hydrochloric acid pickling for surface preparation Can any one tell you consumption of hydrochloric acid and the effluent generated per ton of galvanizing?

In open type hot dip galvanization, hydrochloric acid is typically consumed at a rate of approximately 40 to 100 kg per ton of steel processed, depending on the level of surface contamination and the specific pickling conditions. The effluent generated can vary, but it generally includes spent acid and metal salts, which can amount to around 50 to 150 liters per ton of galvanizing, depending on the specific process and recovery systems in place. Proper treatment and disposal of this effluent are essential to minimize environmental impacts.
