GENERATOR ACID PURIFICATION™ (GAP)

To produce chlorine dioxide, an excess of sulfuric acid and a reducing agent is required, resulting in a residual acid mixture of both sulfuric acid and sodium sulfate. Traditionally, most of the residual acid is sent to the sewer and neutralized with lime. Alternatively, the acid can be returned to the mill’s recovery cycle.

Noram’s GAP™ system offers a solution for separating the sodium sulfate and sulfuric acid to recover the residual acid. The chloride present in the sesquisulfate accompanies the acid and is removed from the recycling process.

Bhy implementing GAP™, you can significantly reduce the lime consumption for neutralization and lower the need for additional acid, leading to both cost savings and a more sustainable use of resources.
