Wastewater Treatment and Potable Water Production
A variety of technologies, including reverse osmosis (RO), ultraviolet treatment (UV), ozonation (O3), chlorine dioxide (ClO2), carbon filtration (CF), and ultrafiltration (UF), have been proposed and practiced for production of potable water and treatment of wastewater. However, application of these processes for surface water disinfection are usually too slow (UV, O3, CF, UF), heavily infrastructure dependent (RO, O3, UV, ClO2), lacking in general applicability towards a variety of chemical and biological contaminants (RO, O3, UV, CF, UF), and often unacceptable in terms of disinfection efficiency (RO, O3, UV, CF). Consequentially, these processes fail to offer a robust and decisively applicable solution addressing all the pertinent sanitary and safety issues associated with the generation of clean water and remediation of waste and contaminated water: complete disinfection, ability to purify fresh, brackish, and salt water, zero residuals of disinfection chemicals, complete absence of disinfection byproducts (DBPs), decisively efficient removal of heavy metal compounds, absolute avoidance of carcinogens and their precursors such as trihalomethane (THM) and polycyclic aromatic hydrocarbons (PAHs), total lack of color and turbidity, and total elimination of odor, to name a few. In order to address all these issues of crucial importance to the safety and well-being of our emergency responders, soldiers, and residents in waterway-contaminated areas, a breakthrough technology for water sanitation and decontamination must be developed, which is robust and decisive in an all inclusive treatment capability, yet built on an integrated single-train system that is compact, rugged, and deployable.
The developed process is a novel, decisively efficient, readily scalable, and robust water reclamation and purification process based on advanced supercritical water oxidative decontamination and concurrent inorganic precipitation separation. Based on our groupí»s extensive experience with supercritical water oxidation and water treatment, the conceptualized process is uniquely capable of accomplishing all of the aforementioned requirements with revolutionary efficiency. A U.S. patent was awarded for this novel process treatment technology and its associated systems.
The current technology can be integrated with our chlorine dioxide technology, thereby producing premium drinking water using literally any source or quality of environmental water.
