Storm water runoff contamination is a problem being addressed more readily by the
U.S. Environmental Protection Agency (EPA). As stormwater flows over land it picks up heavy metals, bacteria, pesticides,
suspended solids, nutrients, and floating materials. In the United States, stormwater runoff from residential, commercial,
and industrial areas is responsible for 21% of impaired lakes and 45% of impaired estuaries. The impacts from stormwater are
caused not only by the pollutants in the runoff, but also by its volume. A National Pollutant Discharge Elimination System
(NPDES) permit, issued to municipal, industrial and construction sites, contains limits on what can be discharged, monitoring
and reporting requirements, and other requirements to ensure that the discharge does not affect water quality or public health.
CWSI's patent pending Add-o-mizer technology entails a process for removing, reducing or minimizing the concentration
of environmental containments found in storm water runoff. Storm water runoff is initially contained in basins,
however, it is eventually released into fresh or salt water bodies and subsequently into groundwater, from which our drinking
water is derived. An ozone diffusion system is used to inject ozone into the water. The process of diffusing ozone
into water occurs much like diffusing oxygen into water. A high transfer efficiency of oxygen or ozone into the water
occurs due to the exponentially increaed surface area provided by the small micron-sized bubbles and the long duration of
bubble persistence. The sytem consists of our Add-o-mizer technology located within the device where production of microbubbles
of oxygen in the 1-10 micron range have been achieved. Standard Oxygen Transfer Efficiencies (SOTE) exceeded 60%, where
Standard Aeration Efficiencies (SAE) of 3.17kg/KW hour have been measured and noted. This technology can be applied
to both water bodies and effluent stream water treatment applications.
