6. 3 Major Solutions From Accent
• Destroy COD causing organics. Unit
can be operated and designed for 0
COD outlet.
• Removes Color from dye house waste
• Destroys recalcitrant COD (Non bio –
degradable organics)

7. Process Chemistry
• COD value is oxygen required for complete oxidation
of organics
• Accent works on the same principle
Reaction 1
- II NaOCl + => CAT - O + NaCl
OCl Ni O RO
Reaction 2 (partial oxidation)

Ni O2 R ORG + CAT - O => ORG - O + CAT
Reaction 3 (total mineralisation)
ORG - O + CAT - O => CO32- + H2 O + CAT

12. ACCENT™ : Main Process Features
• Feed tank
• Pre heating -- Use of plant waste steam.
– Typical operating temperature 30-50 °C
• Controlled addition of dosing chemicals
– Sodium hypochlorite + caustic soda
– Based on feed flow and measured concentration
– Responds to variations in feed
• Hydraulic flow reactor at ambient pressure
– Multiple fixed catalyst beds within one vessel

13. ACCENT™ : Main Process Features
• Continuous monitoring of effluent
– Monitors hypo & contaminants and optimize
dosing.
• Fully automated control
– Continuous measurement of the feed stream
– Requirement for in-line monitoring / control of pH
• Only periodic sampling for pH verification
required
