METHOD OF TREATING AN ACID EFFLUENT CONTAINING PHOSPHORIC ACID

摘要

A method of treating an acid effluent including phosphoric acid in accordance with various embodiments may include: providing an acid effluent including phosphoric acid; adding a base and silicon particles from a further effluent to the acid effluent including phosphoric acid so that a mixture is obtained and a solid content is formed; separating from the mixture a solid content including silicon and a salt resulting from a reaction of the base with the acid, so that a clarified effluent can be rejected in the environment and a filter press cake can be obtained and further used as additive for concrete.
