Microfiltration Reduces Arsenic
to Undetectable Levels
 EAST
HILLS, NY -- Municipal and community water providers are
racing to meet the U.S. Environmental Protection Agency's
(EPA) January 23, 2006 deadline for reducing arsenic in
drinking water. The new ruling reduces the maximum allowable
level of arsenic in drinking water to 10 parts per billion
(ppb).
Pall Corporation announced today
that its membrane filtration technology was granted
verification by NSF International Drinking Water Systems
Center, a partner of the EPA's Environmental Technology
Verification Program, to remove arsenic from drinking water.
Results of the independent performance testing showed that
the Pall Aria(TM) Microfiltration System reduces arsenic to
undetectable levels (below 2 ppb), exceeding the EPA
standard for the maximum level of contaminants allowed in
drinking water. It is the first microfiltration technology
verified to remove arsenic under the new EPA regulation.
"There are many communities
throughout the nation that are underserved in their ability
to meet the new drinking water standards, oftentimes due to
cost," says Jeff Seibert, President of Pall Water
Processing. "The Pall Aria System provides them with a
proven, cost-efficient solution to be compliant with these
regulations for the benefit of the public health."
The Pall Aria System was tested
in several areas of the country with high arsenic levels in
water. In Fallon, Nevada, where arsenic was found at 160
ppb, the system removed arsenic to undetectable levels, less
than 2 ppb. Based on these results, the Fallon
Paiute-Shoshone Tribe is using the Pall Aria System to
comply with the new EPA standard and protect its residents
from arsenic toxicity.
There are about 4,100 small and
community drinking water systems in the U.S.; most serving
less than 10,000 people, where arsenic levels exceed the new
standard. According to the latest EPA report, about 3000
(5.5%) of the nation's 54,000 community water systems and
another 1,300 non-community water systems will need to take
measures to lower arsenic in their drinking water.
Membrane filtration technology is
emerging as the technology of choice for safe drinking
water. Large and small communities around the world
currently use the Pall Aria System to remove parasites,
including cryptosporidia and giardia cysts and oocysts that
can contaminate drinking water and adversely affect public
health. The new verification enables these communities to
remove both arsenic and parasites cost efficiently. The Pall
system is also employed by a wide range of industries to
clean up wastewater to prevent additional arsenic from
entering the drinking water supply.
Unlike other methods of arsenic
removal, such as reverse osmosis and adsorption media,
membrane filtration offers a less costly and long-term
solution. It does not require a major upfront capital
investment, high costs to operate or frequent regeneration
and purchase of media. The Pall Aria System works by the
addition of an iron-based coagulant, such as ferric
chloride, to the water. The contaminating arsenic is
adsorbed onto positively charged ferric hydroxide particles,
which are then removed by microfiltration.
"The arsenic removal verification
opens up a whole new market for Pall Water Processing, which
is currently one of the fastest growing businesses of Pall
Corporation. This past year our sales to municipal and
community water systems have grown over 26 percent," adds
Mr. Seibert.

EPA : Water Contaminant Information Tool
 Washington,
DC -- EPA is pleased to announce the launch of the new
Water Contaminant Information Tool (WCIT) database. This
secure, online database for contaminants of concern to
drinking water and wastewater (water) security is
designed to assist users in planning for, and responding
to, drinking water contamination threats and incidents.
It provides current, reliable, contaminant data from
peer reviewed sources and research.
The database currently
contains data for 48 contaminants. It includes
information on water contaminants data on contaminant
names, contaminant availability, fate and transport,
health effects and toxicity, medical information,
potential water quality and environmental indicators,
sampling and analysis, and helpful response advice for
utilities. Information on wastewater treatment and
infrastructure decontamination will be added to this
tool in 2006.
WCIT access will be granted
to drinking water and wastewater utilities, State
drinking water and wastewater programs, drinking water
and wastewater associations, and federal officials
(including government laboratory personnel.) Given the
sensitivity of the WCIT data, access to the tool will be
tightly controlled with a password-protect feature, yet
it will be readily available to these groups.
To apply for access to WCIT,
visit
http://www.epa.gov/wcit Please contact the
WCIT hotline at
wcit@csc.com or (703) 461-2100 with any questions.

Mohammad needs information on sludge blankets:
We have sludge blanket in
some unit operations like primary clarifiers, secondary
clarifiers and hot lime softeners. What is the suspended
solid concentration in "sludge blanket"?
I think we have to have more
dense sludge blanket to trap smaller suspended solids. Am I
right? (Click
