Better RO
: New High Performance Cleaners Restore Membrane Systems
 Emeryville,
CA -- New Logic Research, Inc., the maker of VSEP, a
vibratory membrane filtration system, announces it's newly
formulated assortment of chemical cleaners, the VSEP
Advanced Cleaning Solutions (ACS), designed to restore
membrane system performance.
Fouling of membranes is a dynamic
and complicated event. The root cause of fouling is rarely
understood, but can occur as a result of a number of
chemical mechanisms. Fouling can even occur as a result of
concentration effects inherent in a system. (See photo)
For example, soluble salts can
precipitate and form scale as solubility limits are
surpassed. Other surface chemistry reactions including
electrostatic charge attractions and hydrophobic bonding can
adsorb foulants that are recalcitrant without chemical
removal methods. Biological fouling can occur in membrane
systems where slime accumulates as a bio-film gel layer on
the membrane surface.
Membrane fouling and scaling can
significantly increase the cost of a membrane system as well
as reduce its reliability. VSEP-ACS can restore your
system's performance.
"Through the years, we have
recommended various commercially available cleaners to our
customers," says CEO, Greg Johnson "but they all had their
drawbacks like being harmful to membrane life, high cost,
and poor performance. In order to better serve our
customers, we set out to formulate the VSEP Advanced
Cleaning Solution, line of high-efficiency cleaners."
"Five basic categories of
cleaners are currently available, one for almost any type of
fouled membrane, cartridge filter, or resin exchange system"
Greg added.
The five unique cleaning
solutions include:
-Organic/Biological Fouling -
Recommended Product: NLR 202
Cleaner Type: High pH Surfactant solution
-Biological Fouling - Recommended Product: NLR 303
Cleaner Type: Alkaline detergent cleaners
-Mineral Scale Fouling - Recommended Product: NLR 404
Cleaner Type: Low pH cleaner with chelating agents
-Organic Fouling - Recommended Product: NLR 505
Cleaner Type: Caustic cleaning solution
-Oil, Wax, and Tar Fouling - Recommended Product: NLR 606
Cleaner Type: Emulsifying Detergent
Environmentally-friendly,
phosphate-free versions are also available. Food-grade
cleaners can also be custom formulated to suit your specific
requirements. To learn more about VSEP-ACS, contact Josh
Miller at New Logic Research.

EPA :
Administration Commits $15 Million to Protect and Restore
America's Watersheds
 Des
Moines, IA -- EPA Administrator Mike Leavitt announced 14
watersheds – representing 17 states – eligible for $15
million from EPA’s Targeted Watersheds Grant Program. The
selected areas represent more than 20,000 square miles of
rivers, lakes and streams across the United States.
“Through this program, EPA lends a hand to local groups
working to protect and restore our nation’s watersheds,”
said Leavitt from the banks of Gray’s Lake, part of the
Upper Mississippi watershed. “With these watershed projects,
we take a critical step forward in providing clean and safe
water for every American.”
Watersheds qualifying for the program stretch from Cape Fear
on the Atlantic Coast, through much of the Mississippi River
Basin, all the way to Dungeness River in Washington State
and the Kenai River in Alaska. Watershed health is
strategically important to providing clean, safe water where
Americans live, work and play. Since 2003, more than $30
million has been provided through the Targeted Watersheds
Grant Program.
The
Targeted Watersheds Grant Program was proposed in 2002 by
the Bush Administration to encourage successful
community-based approaches to protect and restore the
nation's watersheds. This competitive grant program provides
needed resources to those watershed organizations whose
restoration plans set clear goals and objectives with
special consideration given to water quality monitoring,
innovation, a public education component and strong
community support.
Special consideration was given to watersheds along the
Mississippi River Basin, where market-based water quality
trading pilot projects are being implemented to address
excessive nutrient run-off along the River. This nutrient
overload has been scientifically linked to the seasonal
hypoxic – or oxygen starved – zone in the Gulf of Mexico.
Effectively protecting and restoring local watersheds has a
direct impact on the health of our oceans and coastal areas.
The
U.S. Commission on Ocean Policy highlighted this connection
in its preliminary report, stating “the nation’s coastal and
ocean resources are affected not only by the activities in
coastal areas, but also by those in upland watersheds.” The
Commission endorsed programs like the Targeted Watersheds
Grant Program to provide technical and financial assistance
to states and communities for watershed initiatives that
will ultimately protect our oceans and coasts.
Detailed information about these projects and the Targeted
Watersheds Grant Program is available at:
http://www.epa.gov/twg

Saint John Installs
TecStore Tank
Bringing its water system into
the 21st century and complying with provincial standards
were the main goals of the city of Saint John, New
Brunswick, when it decided to install a new potable water
tank. The city’s old riveted tank built in 1935 had
a capacity of 250,000 imperial gallons — not enough to
meet the needs of the 25,000 customers in the city’s
western section, especially in case of an emergency.
