Supercritical Water Oxidation (SCWO) allows the Sievers InnovOx TOC Analyzer to achieve greater than 99% efficient oxidation — regardless of organic compounds and impurities in the water.

Supercritical Water Oxidation (SCWO)

The Sievers InnovOx (short for "Innovative Oxidation") Laboratory and On-Line Total Organic Carbon (TOC) Analyzers use a novel TOC measurement technique based on Supercritical Water Oxidation (SCWO). GE Water’s patented SCWO technique brings water to a supercritical state by heating a water sample inside a sealed reactor module to 375 degrees C and raising the pressure to 3200 psi. Under these conditions, water is neither a gas nor a liquid, but exhibits beneficial properties of both. SCWO allows the InnovOx to achieve greater than 99% efficient oxidation — regardless of organic compounds and impurities in the water. The result is greater TOC measurement accuracy and precision. This new SCWO process also removes all oxidation byproducts and sample contamination between each analytical run, eliminating frequent maintenance and expensive parts replacement

Although SCWO was originally developed to treat large volumes of aqueous waste streams, sludges and contaminated soils. GE Analytical Instruments is the first company to use the SCWO technique in a commercial laboratory TOC instruments.
