Membrane Bioreactor : New Design
Yields Higher Quality Effluent
 Milford,
OH -- An innovative dual-stage membrane bioreactor (MBR) for
advanced treatment of industrial wastewater delivers a
higher quality effluent in less space and with lower
operating costs than are normally associated with
conventional activated sludge processing system. The new ITT
Industries systems take advantage of synergies between two
of its subsidiary companies: Sanitaire and Aquious - PCI
Membrane Systems.
Aquious is a new brand that
envelopes ITT Industries' existing membrane filtration
products and technology, including PCI Membrane Systems,
Inc., Milford, OH. Sanitaire, Brown Deer, WI, is known for
innovative wastewater treatment technologies used in
municipal and industrial wastewater treatment facilities.
Targeted at industrial wastewater
applications in food & beverage production, chemical and
pharmaceutical manufacturing, pulp and paper processing,
metal finishing and steel production, the ITT Dual-Stage MBR
system is a complete and continuous process. It accepts
wastewater with high loadings of BOD, suspended solids and
other contaminants and yields an excellent quality effluent
that can be suitable for direct discharge to surface water
bodies (depending on local regulations) and “low grade”
re-use applications such as vehicle washing. The water can
be further treated with polishing processes (for instance,
reverse osmosis) to yield potable water.
In a traditional activated sludge
process, wastewater is introduced into a biological
treatment tank where organic contaminants are reduced and
nutrients removed. The resultant biomass or sludge then
flows to a clarifier or settling tank where solids separate
out and effluent can be taken off and filtered prior to
disinfection. If higher levels of effluent quality are
required before disposal or re-use, an additional
microfiltration or ultrafiltration step may be required.
Membrane bioreactors, on the
other hand, use the physical barrier provided by an
ultrafiltration membrane instead of a settling tank to
separate solids from liquid. Thus the effluent is of
significantly higher quality and little, if any, additional
treatment is required prior to disposal or re-use.
In the new ITT Dual Stage MBR
system, the biological treatment portion of the process is
kept separate from the membrane filtration stage. Each stage
of the process can then be operated at its optimum
condition. Critical parameters such as aeration rate can be
controlled discretely to minimize cleaning and power costs.
In addition, this configuration provides flexibility that
allows standard designs to be tailored to suit the specific
requirements of different industrial wastewater types.

SSPMA : Effluent Training
Program on Videotape and CDROM
 Northbrook,
IL -- A training video, "Effluent Pumps for Onsite
Wastewater Treatment: Selecting the Right Pump for the Job",
is available from the Sump and Sewage Pump Manufacturers
Association (SSPMA) in both videotape and CD Rom formats.
The program details how to size and select a pump for an
enhanced flow septic tank effluent pump (STEP) system and a
low-pressure pipe (LPP) distribution system.
The
28-minute program includes fact sheets that answer
frequently asked questions and tables to help calculate flow
rates, pump capacity, and pump control differential. It
covers impeller designs, along with applications of each
design. The program gives example calculations for sizing
and selecting pumps for STEP and LPP systems, however, notes
that the same pump selection principle applies to sand,
peat, and mound systems. It shows how to plot the flow rate
and total dynamic head needed on manufacturer’s performance
curves to select the pump.
To
order a copy, along with one set of the worksheet materials,
which can be duplicated for classroom use, send check or
money order (sorry, we don't accept credit cards) for $65
U.S. funds. For a copy of only the video or CD, send
$45.
SSPMA
is a North American trade organization representing over 90
percent of the manufacturers of sump, effluent and sewage
pumps, together with component and accessory suppliers.

Brine Concentrators : Ionics
Awarded Deer Creek Energy Contract
 WATERTOWN,
MA -- Ionics Inc., a global leader in water purification and
wastewater treatment, has been awarded a $7.5 million
contract by Deer Creek Energy Limited, a Calgary,
Canada-based company engaged in development of oil sands
deposits through steam injection and mining extraction
methods.
Ionics will supply two RCC® brine concentrators for
converting two waste streams (produced water from the oil
extraction process and boiler blowdown) into high quality
boiler feedwater. The boiler feedwater is used to produce
steam for downhole injection to fluidize the heavy oil at
Deer Creek's new steam assisted gravity drainage (SAGD)
facility. The project is slated for completion in March
2006.
"We
selected Ionics RCC brine concentrators based on their
proven performance record throughout the world and Ionics'
longstanding reputation for providing reliable, efficient,
and high quality water in our industry. We look forward to
reducing downtime and process upsets with the implementation
of this innovative water purification technology," said Deer
Creek CEO and President Glen C. Schmidt.
The
brine concentrators turn highly saturated industrial
wastewaters into clean water for reuse. Use of this
technology results in lower capital and lifecycle costs in
the production of steam and dramatically increases system
reliability and on-stream availability as compared to warm
lime water treatment processes previously installed in other
SAGD operations. The new equipment has also allowed Deer
Creek Energy to incorporate higher efficiency, lower cost
drum boilers for steam generation into their design,
eliminating the need for once-through steam generators
(OTSG) and vapor-liquid separators.
With
an brine concentrator, greater than 95% of wastewater can be
recovered as high purity distillate, resulting in less than
10 ppm total inorganic dissolved solids. The remaining 5%,
of concentrated slurry, may be reduced to dry solids in a
crystallizer or may be disposed of by other means.
"We
are very pleased to work with Deer Creek on this innovative
application of Ionics' water treatment capabilities. The
contract with Ionics validates its commitment to leveraging
the most advanced cost-effective technologies to achieve an
optimal production level," said Ionics CEO Doug Brown.
About
Ionics Inc.
With
over 50 years of experience in design, installation,
operation and maintenance of water and wastewater treatment
systems, Ionics is a leading global provider of emergency
and long-term water treatment services. More membrane-based
desalination systems have been designed and built by Ionics
than any other supplier worldwide. It's also a leader in
supplying brine concentrators and zero-liquid-discharge
systems, in providing ultrapure water systems for the power
and microelectronics industries, and in the measurement and

AWWA : Statement on NAS Perchlorate Report
 DENVER,
CO -- On Monday Jan. 10, the National Research Council
of the National Academy of Sciences (NAS) released
"Health Implications of Perchlorate Ingestion," a report
assessing the health effects of perchlorate, a chemical
used in rocket fuel, munitions, and fireworks.
Perchlorate has been detected
in drinking water supplies across the nation. The U.S.
Environmental Protection Agency (EPA) is currently
assessing the need for a standard for allowable amounts
of this contaminant in drinking water. Jack Hoffbuhr,
executive director of the American Water Works
Association (AWWA), issued the following statement
concerning this report.
"The drinking water community
takes nothing more seriously than its responsibility to
safeguard the public health. Drinking water
professionals have been researching the occurrence of
perchlorate in water supplies and continue to pay close
attention to relevant health effects research.
"Drinking water professionals
have taken many proactive steps to protect against any
possible health effects associated with perchlorate. The
American Water Works Association (AWWA) is currently
sponsoring a national perchlorate occurrence study that
should yield useful information for the development of
protective federal drinking water regulations. In
addition, the independent American Water Works
Association Research Foundation (AwwaRF) has conducted
several scientific studies on the presence and treatment
of perchlorate that will assist utilities in reducing
the public’s exposure to the substance."

Mr. Steyn
has questions about ink removal:
Hi guys, do any of you have
some tips for working with the effluent ink from the
packaging industry. It is a very messy business
especially when doing jar tests and it is not clear to
see which flocculants and coagulants deliver a good
results.

Peter
needs help with sludge distribution:
As we know, normally we use
sludge age method to control our system. In dry weather, we
can control the system very well. But in wet weather, there
is high flow coming in and high flow situation will keep
several days or two weeks. During this period, the sludge
will be flushed out of the aeration basin and gets into the
clarifiers.
We calculate the sludge age
based on the aeration basins. So, under this condition, we
have to decrease WAS to obtain the desired sludge age.
However, at this time, the sludge blanket will increase and
influence the effluent TSS. So, what should i do to decrease
blanket level? I mean increase RAS or WAS.
I know there is another way
to calculate the sludge age based on the total volume of
aeration basins and clarifiers. Is there person using this
method? How does it work?
