VSEP
Vibratory Membrane Filtration System
First North American Installation for Treatment of Hog Manure
June 6, 2004
New Logic Research, Inc., the maker of VSEP, a vibratory membrane filtration
system, announces it has just completed a sale of its first North American
filtration system to treat Hog Manure. The system will be installed and commissioned
later this summer in Alberta, Canada.
New Logic has previously installed
several manure filtration systems in Korea and
Japan treating both digested manure effluent and
raw manure. These installations in Asia are for
both Dairy Cow Manure and for Hog Manure and have
been operating successfully since May of 2000.
Several companies are currently
working with New Logic to incorporate the VSEP
as the water treatment step in a comprehensive
innovative process where methane gas is recovered
and converted to electrical energy. New Logic has
recently completed a licensing agreement with a
Belgian company who will market and distribute
the VSEP product in Europe for this purpose.
"Taking this waste product
and liability and converting it to valuable byproducts
makes good business sense," says New Logic's
Chief Operating Officer, Greg Johnson. "With
the contribution of VSEP, the hog and dairy farmer
can also harvest electrical energy, concentrated
organic fertilizer, and clean water for livestock
consumption."
The use of VSEP reverse osmosis
filtrate as a source of drinking water for pigs
was recently studied at Ridgetown College, University
of Guelph in Ontario Canada. In his report, Dr.
James Morris concludes that there are no adverse
effects on the health or growth performance of
starter pigs after a prolonged study. Furthermore,
Dr. Morris found that pigs during the later period
of the study actually drank more of the VSEP permeate
than the regular barn water. The report goes on
to say, "The ability to extract water clean
enough without the presence of pathogens will produce
a water quality good enough for drinking water
to pigs. Such a capability would offer a tremendous
benefit in reducing the amount of liquid spreading
and to reduce the amount of water used in swine
operations."
In a recent report, the EPA stated, "Implementation
of environmental regulations can impose compliance
costs on producers and reduce profits. Estimates
of hog producers in the U.S. and the European Union
(EU) put U.S. waste management costs at $0.40 to
$3.20 per hog, which represents 1-8 percent of
total hog production costs for the operations studied,
higher than in previous years because of added
costs of regulatory compliance."
Regulatory restrictions are expanding
on the agriculture industry, but the economic implication
of regulation is a driving consideration. Requirements
that are too strict and too expensive may drive
agriculture to regulation havens in countries or
areas with less restrictive requirements.
According to the News Observer
of Raleigh North Carolina, Dr. Mike Williams, a
North Carolina University official has been charged
with compiling a new technology review for manure
treatment. Williams has extensively investigated
new manure processes and will soon be issuing a
report declaring that at least one new technology
that is "good enough" has been identified.
However at a cost of $400 per 1000 pounds of hog
weight, the price tag for the "good enough" technology
is out of reach of most hog farmers.
For a 2800 head Sow operation,
the estimated operating costs for the manure filtration
system containing the VSEP system alone are estimated
by New Logic Research to be $1.40 per finished
hog. This is significantly less expensive that
other innovative technologies currently being tested
for Hog Manure. Use of the VSEP system would bring
Concentrated Animal Farm Operations (CAFOs) into
compliance with the strictest regulations and can
be done at a reasonable cost within the reach of
most farmers.
Greg Johnson further states, "The
VSEP membrane filtration system is an automated
self-contained device incorporating polymeric reverse
osmosis membranes that provide the water separation.
RO membranes have been used for many years for
desalination and other drinking water applications.
The benefits of reverse osmosis are that the filtrate
will be pathogen free and the membranes are very
effective on all types of dissolved solids removal
and not limited to removal of one or a few contaminants."
Studies have shown that VSEP
reverse osmosis filtration with acidification of
hog manure can provide water with 95% reduction
in Ammonia and 98% reduction in BOD. The typical
manure system will produce up to 85% of the volume
as clean water suitable for reuse. Also, the volume
of concentrated nutrients left over can contains
solids levels as high a 15% by weight and represent
a valuable organic fertilizer product that can
be pelletized or shipped economically as a slurry
to more distant locations where fertilizer is needed. |
