PHT- Ox – Pressure HydroThermal Oxidation
(Wet Air Oxidation)
Removal of Recalcitrant & Toxic
COD > 60,000 ppm
PRESSURE HYDRO-THERMAL OXIDATION
PRESSURE HYDRO-THERMAL OXIDATION
PHT-Ox reactor treats the high COD wastewater using proprietary catalysts and Oxygen. It consists of Plug Flow Reactor on a prefabricated skid. The Spent Caustic from Ethylene Crackers and,
Refinery waste streams are where this technology will be used. Hydrolysis- Oxidation process is intensified for Hydroxyl generation and breaking toxic long-chain molecules.
High COD (Chemical Oxygen Demand) waters are difficult to treat. Biological systems fail due to this COD toxicity. The antibiotics, pesticides, insecticides and micro-pollutants pose a considerable risk to MBBR. CHD-OX Treatment helps increase the biodegradability of wastewater before it enters the MBBR.
Advantages
- Zero chemical sludge generated during the Oxidation process
- Low chemical cost of operation as compared to conventional processes
- Different pressure options are available depending on water quality.
- Low residence time required.
- Potentials for Salt recovery.
- Low CAPEX and reduced OPEX.
