Sionix Announces Filing of Evaporator Patent

Additions to Patent Estate Broaden Opportunities in Energy Space

LOS ANGELES, CA--(Marketwire - March 7, 2011) - Sionix Corporation (OTCBB: SINX), designer of innovative and patented, advanced mobile water treatment systems, is pleased to announce that it filed a patent application February 28, 2011 relating to an evaporation technology that will expand its sales opportunities in the treatment, remediation and reuse of frac and production water in the oil and gas industry where regulatory and environmental oversight have persistently collided with energy consumption. 

As the international economy reels from rapidly expanding energy costs as a result of political turmoil overseas, the urgency to expand safe exploration and extraction of known energy resources trapped in the numerous shale formations in the continental United States, the Bakken reserves in the Dakotas and Montana, ANWR, the oil sands in Canada and other energy shielding geologic formations in North America containing high quality energy reserves, the threat of contaminating adjacent resources can be significantly reduced as a result of new treatment technologies from Sionix Corporation and others, including complementary technologies like the evaporation technology captured in this important patent application. 

The perfection of this new process along with the functional design of the Sionix Mobile Water Treatment System and the underlying, proprietary Dissolved Air Flotation technology; their collective efficiency of application and favorable environmental profile enhance Sionix' expanding intellectual property, enlarge its current patent and intellectual property portfolio, and develop its reputation as a responsible, environmentally conscious, worldwide corporate citizen. 

This new evaporation technology is elegantly simple, both in design and application. The process itself involves an open cycle direct cooling evaporative cooler, essentially operated without regard to the cooling function (in other words, the complete opposite of the "swamp coolers" that those of you living in desert climes are familiar with). Contaminated water is circulated through "cooling pads" constructed of multiple filaments similar to corrugated cardboard that are fabricated along the longitudinal walls of a standard 40' ISO shipping container. Ambient air, drawn from the outside through the cooling pads and exhausted through the center ceiling of the container, evaporates the water pumped through the cooling pads from the top of the container leaving readily recyclable solids of contaminants embedded in the cooling pads. The cooling pads can be baked or heated, at moderate temperatures, to drive off any residual water content and the dry contaminants, which include salt, small amounts of metals, organic compounds and other solids can be processed for use in other applications and resold as an additional revenue stream.

Much regulatory attention is directed to the disposal of water contaminated as a result of hydraulic fracturing techniques. Pennsylvania, where much of the Marcellus shale formation is located, recently passed legislation (effective January 1, 2011) that prohibits water used in the drilling of natural gas wells from being discharged into waterways unless it is first treated to remove the salts and minerals that are contained in the water that flows back ("flow-back water") to the surface. Currently, much of the waste water from the drilling process is trucked off-site to commercial and municipal sewer treatment plants at a high cost, or transported long distances for injection into a disposal well (which may be located in another state). In either case, both solutions are prohibitively expensive and are absorbed by consumers in higher energy costs. The Sionix evaporative technology provides an inexpensive disposal of produced water and its contaminants, not only minimizing the environmental impact but the cost impact to energy consumers.

With Sionix' growing participation in the production of alternative energy through anaerobic digestion, and now with the addition of this complementary technology for use with the existing MWTS, Sionix can now play a more decisive role in the remediation and reuse of precious water resources currently being exhausted from our watersheds at alarming rates, and contaminated with man-made toxins "mother earth" cannot efficiently remediate.

The attorney docket number for this application is 213-241 and will appear on the Sionix and USPTO websites shortly. To date, Sionix has nine patents issued and four patent applications on file.

About Sionix Corporation
Based in Los Angeles, CA, Sionix designs innovative and advanced water treatment systems intended for use in defense, government facilities, emergency water supplies during natural disasters, housing development projects, and various industrial processes including subterranean fracturing used in oil and gas drilling. These systems are located adjacent to contaminated water sites thus reducing cost and toxic exposure and can be used to remove organic materials including oil, waste and other infectious bacteria from contaminated resources. They can be also used as pre-treatment for reverse osmosis and other membrane applications. Industries involved in dairy, agribusiness, meat processing, mining, poultry operations, and many others can benefit from Sionix's cost-effective, easily maintained, portable water treatment systems. For more information about the Company, go to

About Sionix Technology
Using a patented dissolved air flotation (DAF) technology packaged in a mobile shipping container, air bubbles between the size of 1 and 2 microns are injected and float organic contaminants to the surface where 99.95% are skimmed off. This compares to standard DAF units which historically have been limited to using bubble sizes of 50 microns or larger. The size of these bubbles are important because the smaller the bubble, the greater the surface tension and the greater the electrical charge. They can then hold together longer and elevate more organic contaminants to the surface for removal.
