RETRACTED: Supercritical water oxidation for the destruction of toxic organic wastewaters: A review

Selecting sewage sludge treatment alternatives in modern wastewater treatment plants using environmental decision support systems

“…The combination of both factors points out the most promising option regarding the GWP parameter. It is to be highlighted that, specifically, SCWO is widely proposed as an environmentally friendly alternative to incineration (Veriansyah and Kim, 2007;Boachen et al, 2009;, which is a fact that has been shown and strongly confirmed in this work through the NovEDAR_EDSS software. With a sludge residence time of a few seconds, SCWO is able to remove more than 99% of the organic matter releasing the following major products: water, CO 2 and inorganic solids [which could also be further exploited to recover phosphorous (Stark et al, 2006) and even precious metals (Matthey, 2003); however, although this valuable production has not been taken into account in this work, since it is novel and far from being implemented as a common procedure related to SCWO].…”

Notice of Retraction: Reaction Mechanism and Influence Factors of Ethylenediamine Wastewater Treated by Supercritical Water Oxidation

“…Currently, for wastewater containing more than 1% EDA, controlled incineration was usually adopted as the major treatment method. To attain high destruction efficiency, incineration must be operated at very high temperature (900-1100 ℃), which means high cost [7].…”

Mn–Ce–Co complex oxide nanoparticles: Hydrothermal synthesis and their catalytic subcritical oxidation of 4,4′-Dibromobiphenyl

“…Supercritical water oxidation (SCWO) is a very effective way to degrade organic pollutants because most organic pollutants and oxidants can dissolve in supercritical water to form a homogeneous phase [8][9][10][11][12][13][14][15]. Although SCWO shows great potential in degradation of organic pollutants, many problems such as deposition of salts, corrosion, and the high temperature and pressure of the critical point of 647 K and 22.1 MPa cause it very difficult to be applied to industrial utilization.…”
