In some instances, you may be faced with treating 'difficult' liquid wastes containing hard COD, AOX (Adsorbable Organic Halides), pesticides, colour and odour. Air Products has developed it's CHEMOX™ ozone technology for the treatment of such contaminants and by utilising a unique, patented reactor design, the CHEMOX™ solution is an extremely cost effective approach to dealing with difficult contaminants. CHEMOX™ can be used either as pre-treatment prior to a biological process or as polishing after a biological process.
