Engineering today for a Greener Tomorrow
Wastewater treatment faces hindrances from the myriad contaminants that enter the
environment through industrial and domestic sources on a daily basis. The
biodegradable compounds often get degraded or mineralized by various physical,
chemical or biological processes, whereas the recalcitrant organic contaminants either
are transformed or get dispersed and persist in the receiving environments, to an
extent much greater than was earlier estimated. Conventional treatment plants do not
address these problems.
≋CHD-Ox≋ Reactor
CHD-Ox - is a Catalytic Hydro-Oxidation reactor with proprietary Catalyst and
micronising system. This process combines 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. 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
New catalytic formula enhances the rate of degradation in the process
Minimum retention time is 4-6 hours, higher retention gives better results
