Hydrogen peroxide to remove free chlorine
Thread Content
Is there any plant that uses hydrogen peroxide for the chemical removal of free chlorine after the dechlorination tower? What are the process details and the effectiveness? For the salt produced, is it necessary to add acid again for descaling and denitration? Is sodium bigayate more cost-effective?
Hydrogen peroxide is an oxidizing agent, not a reducing agent, and cannot replace sodium sulfite
Hydrogen peroxide is used very frequently as a strong oxidizing agent, but here it acts as a reducing agent in its role as a dechlorinating agent. I think it was said that hydrogen peroxide can act as both an oxidizing agent and a reducing agent.
We have used it, and it causes considerable corrosion to the equipment pipelines
What is the material of the pipe, and does it have an inner lining?
How is that pipeline equipment protected against corrosion?
It is possible to use hydrogen peroxide under vacuum after dechlorination, but an excessive amount should not be used, as this would result in too strong oxidizing properties; high precision is required for the operation. In principle, hydrogen peroxide cannot be used directly to completely remove free chlorine.
