Manure Separators in
Demand on Animal Farms
Warren, RI, June 5, 2008 --- Large CAFOs
(concentrated animal feeding operations) have been processing their
manure through solids separators for both the manure management and
financial benefits. With a greater variety of sizes on the market,
including Pro-Act Biotech’s line of separators, Pro-Act reports that
animal farms of many sizes are placing orders for this technology.
Pro-Act’s Separator, produced by the Vincent Corporation of Florida,
separates the manure into two streams: manure slurry and the solids.
The liquid is then drained into a waste lagoon or storage tank while
the dry solids can be put to a variety of uses including compost,
fertilizer and animal bedding. Separating the solids out of the
manure stream also results in a less stressed lagoon/tank.
Pro-Act’s biological manure treatment is key to decreasing the
solids in storage, dramatically decreasing the odor, controlling
nutrients, providing easier access to superior fertilizer and more.
When this technology is used in conjunction with the Pro-Act
Separator, the benefits are even greater. Because of this and due to
the rising prices all around and shortages of fertilizer looming
well into the future, Pro-Act Biotech is reporting a recent surge in
orders for their separator.
Solids separation is an excellent way to extract the nutrient-rich
solids for use in other applications such as fertilizer or
composting. The fertilizer value of Pro-Act treated manure is much
better than untreated, and taking out recalcitrant solids with a
separator further enhances the manure treatment. So the separation
and biological treatment together decreases or even eliminates the
amount of nitrogen fertilizer the farms need to purchase.
And the financial benefits go beyond fertilizer. Keeping bedding and
manure out of the treatment pond extends lagoon life. This reduces
the frequency necessary to dredge the lagoon. And when it does come
time to pump, Pro-Act’s biological manure treatment results in
lagoons that do not require agitation, further increasing time and
The drier solids that come out of the separator are also much easier
to apply to fields and incorporate into compost. In fact, some
farmers are selling this compost in bulk to nurseries and
municipalities, while others are bagging the material for retail
sale to home gardeners.
Another money-saver is to use the manure solids as bedding.
University studies have shown that pressed manure has just the right
moisture content (70%) for composting. This raises the manure
temperature sufficiently to kill bacteria, thus making the compost
safe for use as bedding. Plus, in flush systems, the microbial
component of Pro-Act’s treatment sanitizes the bedding further.
The Pro-Act Separator is designed to work on many farm types: dairy
or hog, flush or scrape barns. In flush barns, Pro-Act's microbial
mix has already gone to work reducing the odor and viscosity of the
water and solids before the manure slurry reaches the separator.
This makes the separator work more efficiently and puts less wear
and tear on the equipment. With scrape barns, the manure is thicker.
Separating the solids out of the manure stream results in a lagoon
or storage tank that is less stressed and provides an environment
for Pro-Act’s treatment to work even better.
“We’ve had quite an interest in our separator since we introduced it
at the beginning of this year,” says Bill Campion, president of
Pro-Act Biotech. “Times are getting a little tighter and the farmers
are understanding that manure separation is really needed not only
as a standard part of manure treatment but also as a way to put the
manure to work for them.”
