 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
