VSEP Trials Completed for Acidic
Phosphate Wastewater
 Emeryville,
CA -- The Florida Institute for Phosphate Research (FIPR)
awarded a research grant to New Logic Research, Inc., of
Emeryville, California to study the use of its reverse
osmosis membranes for treatment of acidic process water
stored in large ponds known as phosphogypsum stacks. The
pilot trials were recently completed at an active phosphate
plant in Bartow, Florida and the results prove the patented
VSEP Vibrating Membrane Filtration System efficiently
filters the wastewater, producing filtrate suitable for
surface water discharge.
The typical phosphogysum stack
covers 600 acres and contains billions of gallons of very
low pH wastewater made up of hazardous and even radioactive
substances that cannot be discharged without treatment.
Treating this volume of water with traditional methods
requires very large quantities of lime and creates even
larger quantities of residual sludge that also must be
disposed of.
An active phosphate pond contains
about 5% dissolved solids. After VSEP reverse osmosis
filtration, the effluent contains less than 0.005% dissolved
solids—water clean enough to meet stringent Florida
Department of Environmental Protection standards for surface
water discharge. And unlike traditional lime treatment, VSEP
treatment does not create large volumes of sludge, which
creates additional cost and handling issues.
New Logic Research CEO Greg
Johnson states that “Conventional reverse osmosis membranes
with pretreatment have been used for many years for seawater
desalination. However, these systems have limited
functionality when used for other wastewaters containing
high levels of scale forming minerals. VSEP, a vibrating
membrane system which employs torsional oscillation of the
membrane media, is capable of filtering these difficult
wastewaters as a standalone system without any pretreatment
or added process complexity.”
About New Logic Research, Inc.
Headquartered in Emeryville,
California, New Logic Research is the leading provider of
high-performance membrane filtration systems used in a wide
variety of applications from pure water and wastewater
treatment to chemical process clarifications.

tank will feature an aluminum geodesic clear-span dome roof
system. The tank and dome systems will be supplied by
Engineered Storage Products Company of DeKalb, Illinois,
USA. Engineered Storage Products Company is an operating
division of CST Industries.
The
tank wall sheets will be internally coated with Engineered
Storage Products Company’s proprietary Kuo-Lon® modified
epoxy coating system. This state-of-the-art coating is
specifically designed to minimize long-term maintenance
requirements, a crucial issue for the Keppel Seghers’ 20
year DBOO contract.

New Pump Software Helps Reduce
Energy Costs
 Londonderry,
NH -- Pump & Systems “Basic” and “Pro” software has recently
been released by Process Energy Services to help facility
managers and operators identify pump system energy savings.
According to the Hydraulic Institute, “U.S. Department of
Energy (DOE) studies indicate that pumping systems account
for nearly 20% of the world's electrical energy demand and
range from 25% to 50% of the energy usage in certain
industrial plant operations. Case Studies have shown that
better system design and more effective application of pumps
can usually save 20% or more in energy costs and represent a
large, frequently overlooked savings opportunity.”
Steve
Bolles, President of Process Energy Services states that,
“Many facilities are simply satisfied if a pump delivers
water at a reasonable pressure and flow. However, when a
pump is under performing, it is difficult to determine how
much energy is being wasted unless an engineer performs a
detailed analysis. Pump & Systems software was developed to
provide a simple, easy to use interface to optimize pump
system operation and reduce energy costs”.
The
software can be set-up easily by entering pump flow,
pressure and efficiency values using data from the
manufacturers pump curve. Basic system information such as
electricity cost, pipe length, and hours of operation can be
entered and changed right on the main results screen.
Process Energy Services has tested the program at several
facilities with impressive results:
-Facility operators at a wastewater pump station discovered
that a simple tank level adjustment could reduce pumping
system energy costs by over $10,000 annually with no capital
investment.
-Over $45,000 in annual savings was identified when the
software was used to evaluate multiple parallel pump at a
golf course irrigation system.
Process Energy Services is a New Hampshire based energy
consulting firm specializing in energy consulting work for
municipal and industrial facilities.

 Fort
Lauderdale, FL -- Biolac® System chosen to meet unique
challenges for this application. In keeping with its
environmental initiatives, the Cincinnati/Northern
Kentucky International Airport will expand its Elijah
Creek Stormwater Treatment System to keep aircraft
deicing chemicals out of local streams.
The Biolac® extended aeration
activated sludge treatment system was recently selected
to treat the stormwater from the airport’s deicing
runoff, which includes glycol and potassium acetate.
With an influent average flow of 5.0 MGD, the Biolac
System will be installed into the current 15 MG
equalization basin and will treat an average of 30,000
lbs of BOD per day. This will replace two sequencing
batch reactors, and the SBR tanks will be converted to
sludge holding tanks. The installation will incorporate
Parkson’s flat bottom type SS Clarifiers, which use the
innovative SuperScraper™ Sludge Removal System to remove
settled sludge.
The Biolac System met several
unique treatment challenges for this application:
-Treatment of deicing wastewater with a minimum
temperature near 0o C.
-Treatment of widely varying wastewater loads. This
plant is designed to treat BOD loads varying from 1,000
to 30,000 lbs/day, with the ability to absorb one-day
peak loads approaching 60,000 lbs/day.
Owner is the
Cincinnati/Northern Kentucky International Airport. The
Engineer for this project is URS Corp. of Cincinnati,
and Contractor is Danis Environmental Industries of
Dayton, OH.

Ms. Stromvig needs with lime
additions:
I have a process effluent at
an average flow of 2,812m3 at pH 3.8 and want to raise the
pH to 7 using hydrated lime. I've tried to calculate how
many kg of hydrated lime powder I would need (available
CAO=60%) but am getting very small amounts <25 kg.
Can anyone outline how I
should be doing the calculation

Mr. Parrott needs input about aquaculture:
We are interested in
exploring the challenges and opportunities related to
raising fish fingerlings or minnows in tertiary treatment
ponds. The ponds have all the necessary ingredients for
success; abundant, clean and fertile water that will support
fish fry without additional feeding. Our larval fish will
feed on Daphnia, blood worms and mosquito larvae so they may
help eliminate these pests from existing systems.
Integrating aquaculture into
wastewater treatment plants would put a positive spin on
effluent and help promote it as an untapped and valuable
resource. We are looking for input from wastewater treatment
professionals like yourselves. Your thoughts and
comments will be appreciated. (Click
