CHD-Ox Catalytic Hydro-Oxidation for Recalcitrant COD

CHD-Ox Catalytic Hydro-Oxidation for Recalcitrant COD

≋CHD-Ox≋ Reactor
CHD-Ox - is a Catalytic Hydro-Oxidation reactor with a  Catalyst and micronising system. This process combines the phenomenon of intense micro-bubble oxidising, cavitation, enhanced mass transfer. This is introduced as a precursor to any Biological treatment, especially the MBBR tanks having problems of toxic and recalcitrant COD/BOD

Process Description
Advanced Oxidation technology uses Duplex Batch Reactor or Continuous Radial flow reactor for the treatment. The process further combines with downstream MBBR process, Membranes technology, VAPOZEM low OPEX evaporation technology for final waste treatment polishing to achieve water recycling norms and discharge norms Volatile acids and other organics present in the condensate can be degraded into
simpler, non-toxic molecules. 
The new catalytic formula enhances the rate of degradation in the process
Minimum retention time is 4-6 hours, higher retention gives better results

Vacuum fused cavitating Micronisers create fine micro-bubbles and millions of tiny bubbles are generated. The basic premise is that, if we can increase the surface area in a two-phase reaction between gases and liquid we would have very fast, efficient mass transfer.

Vacuum fused Porous Micronisers far exceed the performance of drilled pipe and other types of diffusers. These have thousands of pores over the surface. Defined morphology specific to the manufacturing process allows large volumes of gas be passed creating very high specific area at the interface.
With equal volume of gas, 1 mm bubbles would have 600 times more gas-liquid contact surface area than 6 mm bubbles, and the magnitude is much higher with microbubbles.
