HOG WASH™ Bio-Technology
Effective Hog Lagoon Odor Reduction, Barn Odor Reduction, and Water
Treatment Process
Environmentally Sound Manure Management
The fresh and wastewater treatment process developed by ENSOL, L.L.C.
and trade named "HOG WASH™" uses a unique and patented carbon
material developed in Australia, and an exclusively available bacterial
product which work synergistically to digest and break down manure solids
to a nutrient enhanced liquid.
The HOG WASH™ treatment is completely safe for hogs and humans.
When placed in the pits and lagoons, the treatment removes residual antibiotics
and enhances the colonization of the introduced proprietary bacteria,
giving efficient manure digestion, the cessation of odorous gas production
yielding a liquid effluent, which surpasses the crop growing performance
of commercial fertilizers.
Testing at Iowa State University by Professor Dwaine Bundy and Dr. Daniel
Meyer gave results for odor and hydrogen sulfide reduction up to 97%.
The HOG WASH™ treatment process has been used in NW Oklahoma over the
past three years, not only keeping odor at a very low level but also providing
additional benefits. The resulting nutrient rich liquid is red in color,
free of solids for easy distribution through irrigation spray systems
and has high value as a slow release fertilizer. Testing with wheat and
Blue Stem Grass has shown over double the yield compared to a commercial
fertilizer.
The following are observed results over 3 years of field tests using
the HOG WASH™ treatment:
| Observation |
Positive Impact Observed |
| 1. Odor condition |
*The ammonia smell in the barns and emanating from the lagoons was
immediately eliminated.
*Sulfide gases were reduced about 97% in the barns and from the
lagoons.
*The effluent has a pleasant fruity smell, in the lagoon or sprayed.
|
| 2. Impact on the hogs |
*The HOG WASH™ water management
protocol resulted in a substantial pre-wean mortality reduction.
*There was an improved weight gain of baby pigs.
*Reduced sow morbidity and still births.
* A marked reduction in severity of and the treatment needed for
E. coli scours, with savings in labor and medication costs.
*Reduced flies and insects gave improved animal health with a reduction
in respiratory and insect borne infections.
|
| 3. Impact on humans |
*Pleasant smell replaced the noxious effluent odor which meant happier,
more productive employees.
*Positive comments from neighbors, contractors and inspectors.
*Greatly reduced odor clinging to clothing or skin.
|
| 4. Environmental impact |
*Removal of the crust removes breeding sites and greatly reduces
the fly and gnat population in and around the farm.
*The fruity smelling effluent is recyclable into most barns, saving
some 80% on fresh water usage.
*The liquid effluent pumps freely for easy use in spray irrigation
systems, no solids spreading or manure injection is needed.
*Phosphorus is released and nitrogen is fixed, both enabled for plant
up-take, eliminating phosphorus build up and excessive nitrate run
off.
*The compost nutrient value of the soil is enhanced with improved
microorganism count.
|
| 5. Impact on Crops |
*The spray irrigated effluent has slow release nitrogen nutrient
and gives lush green foliage, not yellow crops.
*Grain crops with much higher yield over commercial fertilizers. |
| NOTE: |
Although the treatment has a cash cost, the benefits of using the
HOG WASH™ treatment outweigh that
cost in both real and hidden operating cost reduction (see Attachment
A).
Our process changes raw hog manure into a composted effluent with
high fertilizer and cash value. One hog grower said he wished he
could make a lot more to pump through his irrigation system, describing
it as "liquid gold".
The use of the HOG WASH™ process is highly beneficial in public
relations with the community, provides for better crop production
with sound environmental management and removes the odor, the overwhelming
reason for complaint against hog rowing operations.

Chuck and Wathina Luthi
"My main concern was the odor of the lagoons, and over the course
of time, we have seen a drastic change in color in our 2nd stage that
happened last year, and after the warm weather set in this year, it
turned red pretty quick. Of course, after that the odor went down
tremendously. What we're seeing now in our first stage lagoon is a
color change, and right along with that, a reduction in surface build-up
of crust and a reduction in odor which is pleasing."
