Upstream BrochureSource: UV Pure Technologies
Upstream Systems with patented Crossfire Technology are validated to achieve the same standards as NSF/ANSI 55 Class A, but are not certified, where regulations do not require it. Field-tested and proven with over a decade of demanding municipal, industrial and commercial applications.
Dissolved organics and high tannin content are the primary contributors to the reduction of UV Transmittance (UVT) in surface waters. Tannin content and low UVT render conventional UV technology ineffective. Our Upstream units are engineered specifically for these types of cases where others fail.
Upstream is engineered to reduce e-coli, bacteria, cysts like cryptosporidium and giardia, legionella and most viruses to safe levels –a minimum of 99.99% reduction. Upstream systems are effective for the broadest range of pre-treatment water quality with UVT as low as 50%.
