Sanford, FL, July 6,
2006 - Argonide’s patented NanoCeram®
technology has staked a claim in the demanding membrane prefiltration market. The Sanford,
Florida-based company manufactures a full line of standard filter cartridges based on their patented
NanoCeram® electropositive media. This media yields SDI (Silt Density Index) values
averaging < 0.5 with turbidity levels < 0.01 NTU when incorporated in standard pleated cartridges.
These results will often out-perform many UF devices currently used in ultrapure water systems.
Considering the
significant cost factors for today’s RO filtration systems, protecting a typical system
becomes an economic necessity. Virtually all RO manufacturers specify a feed water stream
with < 1.0 NTU and SDI levels of <5.0, with many preferring levels < 3.0. SDI is an
empirical test used to characterize the fouling potential of a feed water stream. The test
is based on measuring the rate of plugging a 45 micron filter using a constant 30 psig
feed pressure for a specified period of time. SDI30 refers to a silt density
index test which was run for 30 minutes. For example, spiral wound systems typically
require an SDI < 5.0 and hollow fiber systems require an SDI < 3.0. Most deep well waters
have an SDI of 3.0 and most surface water have SDI’s greater than 6.0.
For the purpose
of presenting a fair comparison of commercially available prefilters, Argonide tested
their NanoCeram® filter cartridge against several well-known prefilters for RO
systems. The results from those laboratory tests are available and exhibit NanoCeram®’s
significant advantage in removing submicron particulate when compared to other
commercially available filter cartridges typically used as prefilters to RO systems. Even
under extreme loading, NanoCeram® yields ultra-low SDI values (averaging < 0.5)
and NTU levels often below detectable levels - providing long-lasting protection of RO and
even UP membranes susceptible to premature fouling.
Comparisons to
UF and MF solutions for R.O. system pretreatment are favorable given lower capital
investment costs, overall energy costs versus pressure-driven systems, decreased system
maintenance costs, lower waste disposal costs, and less water waste.
