  • Treatment of whey wastewater by supercritical water oxidation

    Whey wastewater is a by-product of cheese industry, which causes environmental pollution problems due to its containment of heavy organic pollutants. Conventional methods such as biological treatment and physico-chemical treatment are insufficient or ineffective. In this paper, the treatment of cheese whey wastewater has been carried out by supercritical water oxidation, using hydrogen peroxide ...

  • New Green Methodology for Measuring Total Organic Carbon (TOC) — Supercritical Water Oxidation (SCWO)

    Analyzing the total organic carbon (TOC) content of industrial wastewater, process influent and effluent water, and environmental water samples can be very challenging. These aggressive sample matrices often clog or damage TOC analyzers that use the combustion method. This can result in expensive preventive maintenance and excessive non-regenerative waste. To address these critical issues, GE ...

  • Supercritical water oxidation presented as alternative to incineration – An update

    Environmentally benign waste disposal is becoming a more and more acute problem. A process now being commercialised, supercritical water oxidation is demonstrating extremely efficient organic waste destruction (99.99%) plus excellent environmental characteristics (none of the emissions associated with incineration). The process is especially suitable for the treatment of wastewater and sludges ...

  • Supercritical water oxidation of sewage sludge – state of the art

    Supercritical water oxidation (SCWO) is an innovative and effective destruction method for organic wastewater and sludge. Several tests of the destruction of sewage sludge by SCWO have been done at two state of the art pilot plants. These units have capacities of 250 kg/h and 1100 kg/h, respectively. The test results show that the technology easily destroys the organic material in the sludge and ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...
