The SPR-COD series of specialized resins for COD removal in wastewater are developed by SepriTech for the treatment of organic wastewater. They exhibit excellent removal efficiency for hard-to-biodegrade cyclic compounds and can be used in the pretreatment of organic wastewater, pharmaceutical wastewater, pesticide wastewater, and chemical wastewater to improve biodegradability. They are also applicable in post-biological treatment for advanced COD removal and decolorization of wastewater. The SPR-COD removal resin has the following application areas:

1. Treatment of organic acid wastewater

2. Treatment of organic amine wastewater

3. Treatment of phenolic wastewater

4. Treatment of solvent-containing wastewater

5. Wastewater decolorization

6. Wastewater upgrading (advanced COD removal)
