About Sionix Technology

The Sionix Mobile Water Treatment System for fluids management and water treatment addresses a broad spectrum of contaminant conditions in totality. Using a customized technology configuration, each system tailors its technology suite to address each customer's specific treatment needs. The dynamic nature of influent contamination dictates treatment parameters which may continually be in flux. The modularity of the technology suite within the Sionix MWTS allows for the ease of adaptation to these fluctuating contaminant conditions. A unique component highlighted within the Sionix systems is the Sionix patented and proprietary Dissolved Air Flotation technology, which generates micro bubbles between the size of 1 and 2 microns, compared to historical sizes of 50 microns or larger. The actions of these micro bubbles facilitate the removal of 99.95% of organic contaminants and a majority of inorganic contaminants. The evolution of this technology is exclusive to the Sionix Water Treatment Systems.
