Why is waste acid treatment equipment in steel pipe plant so important

2020-06-18

Waste acid is far more harmful to groundwater than ordinary chemical wastewater. When it seeps into the ground, it also reacts with carbonates, sulfites and sulfides in rocks and soil to produce harmful gases such as sulfur dioxide and hydrogen sulfide, which are emitted into the air and pollute the atmosphere. Therefore, China has strict requirements for the treatment of waste acid, and there are different punishment standards and emission standards throughout the country.
Due to the wide range of sources and distribution of waste acid, the concentration and composition of waste acid produced by different industries are very different. It is impossible to have a simple and unified way to control waste acid. We must rely on the technological progress of acid-related enterprises and related industries to solve the problem.

Waste acid treatment equipment in steel pipe plantIt can help you to concentrate and crystallize ferrous chloride in waste acid pickling hydrochloric acid, increase the concentration of waste acid hydrochloric acid from 5% to 20%, and then mix and recycle with new acid, thus helping you to solve the treatment problem of waste acid pickling hydrochloric acid. You don't have to spend high fees to find qualified units to deal with, not to mention the constant urging and supervision of the environmental protection department.
Waste acid treatment equipment in steel pipe plantThe working principle is: using the acid resistance characteristics of ion exchange resin, the waste acid in the waste liquid is adsorbed on the resin, and other metal salts pass smoothly, and then the resin is analyzed with pure water to recover the acid.
Ion exchange resin is used to adsorb strong acid and remove metal salts in the solution to achieve the purpose of separating free acid and metal ions. In the later stage, waste water purification equipment is added to achieve zero discharge. The cost of wastewater discharge can be greatly reduced.
Waste acid treatment equipment in steel pipe plantWide application range and simple operation. Large processing capacity, high cost performance (compared with membrane acid recovery equipment), can be selected according to water quality and water quantity requirements, adjustable high, to avoid waste of funds. The equipment has a long service life and low maintenance rate. Normal temperature regeneration, low energy consumption; complete sets of acid recovery equipment can achieve zero emissions.
