AUTOMATED SAMPLING SYSTEM

 

A brief case sized field-portable chromatography instrument designed to test water samples. The automated sampling system floats in a body of water and continuously extracts and tests samples. The data gathered by the system is wirelessly transmitted to a shore-based date processing unit.

Potential Commercial Applications:
- Ion chromatograph to analyze dissolved anions or cations autonomously on site

Competitive Advantages:
- Collects real-time and accurate water quality data for long periods without maintenance or servicing
- The instrument is portable, automated and not labor-intensive
- Operates on solar or self-contained battery
- The device can be submerged in water

METHODS FOR PRESERVING UNTANNED ANIMAL HIDES

 

Methods for preserving untanned animal hides involving contacting the hides with an aqueous suspension and less than about 25% salt (W/W).

Potential Commercial Applications
- Preservation of  hides

Competitive Advantages
- Environmentally friendly low salt preservation process
- Low salt thus shorter time to remove excess salt and less water to restore the cured hides

HEAVY METAL REMEDIATION VIA MODIFIED BIO-OILS

 

A process for the removal or extraction of metals, including heavy metals, precious metals and other metals, from a variety of solid, liquid or gas phase materials. Metal species are removed by contacting the material suspected of containing one or more metals with a fatty acid (or ester) for a period of time and under conditions effective for the sequestration of the metal species. The fatty acid or ester comprising of sequestered metal species is insoluble in water and may then be separated and recovered from the treated material.

Potential Commercial Applications
- Removal of toxic metals from contaminated drinking water and other fresh water systems (such as lakes, ponds, estuaries, rivers and streams
- Removal of toxic metals from waste discharge streams of agricultural, municipal sewage and from contaminated soil from agricultural
- Removal of toxic metals from industrial or mining sites and from flue gases discharged from commercial or industrial sites

Competitive Advantages
- Ability to conduct remediation in an environmentally friendly, biobased manner
- Simplicity of process to localized contaminations such as spills, offers a broader range of markets
- Over 90% by weight of the metal species content, preferably 99% or more, can be removed from the material being treated

PROCESSES AND TREATMENT SYSTEMS FOR TREATING HIGH PHOSPHOROUS CONTAINING FLUIDS

 


A process for treating manure slurries to concentrate manure particulate matter into solid form that is easily transportable. The process involves liquid-solid separation and chemical treatment where greater than 90% of the total phosphorous is concentrated into solid form while most of the nitrogen remains in the liquid.

Potential Commercial Applications:
- Efficiently remove livestock manure phosphorus from areas of excess to areas of shortfall

Competitive Advantages:
- Economical
- The system can be compact and mobile

COMPOSITIONS AND METHODS OF TREATING ANIMAL MANURE

  

Manure amendment and method for controlling ammonia emissions from poultry litter and reducing phosphorus runoff. The manure amendment is produced by adding various combinations/ratios of sulfuric acid, bauxite and water to alum mud, a waste product from manufacturing alum (aluminum phosphate).

Potential Commercial Applications
-Controlling ammonia emissions from poultry houses and reducing phosphorus runoff
- Treated manure lowers the concentration of ammonia in animal rearing facilities and improves environmental, health and/or animal performance     

Competitive Advantages  
- The manure amendment is economical to produce
- Has many of the properties of aluminum sulfate
- The exact formulation of the final product can be tailored to fit specific manure type

NITRIFICATION-ENHANCED AMMONIA SCRUBBER FOR ANIMAL REARING FACILITIES

 

Method and apparatus for controlling ammonia emissions from animal rearing facilities. The system is comprised of a dust scrubber in series with an ammonia scrubber which removes ammonia from the air. The ammonia is converted to nitrate by acid-tolerant nitrifying bacteria. The nitrification process produces acid, which reduces the pH of the scrubber solution in the ammonia scrubber, allowing the scrubber to capture additional ammonia.

Potential Commercial Applications
- Removal of ammonia and dust exhausted from animal rearing facilities, such as poultry and swine houses

Competitive Advantages
- Nitrification-enhanced perpetual acid generator. The acid is used to scrub ammonia exhausted from animal rearing facilities
-Resulting nitrogen-rich product solution can be used as fertilizer

PSEUDOMONAS SPECIES HAVING WEED-SUPPRESSIVE ACTIVITY AND BENIGN SOIL SURVIVAL TRAITS FOR ANNUAL GRASS WEED MANAGEMENT

Weed-suppressive Pseudomonas fluorescens bacterial strains effective for controlling one or more invasive grass weeds such as downy brome (cheatgrass, Bromus tectorum L.), medusahead (Taeniatherum caput medusae (L.) Nevski) and jointed goatgrass (Aegilops cylindrica L.).


Potential Commercial Applications
- Cheatgrass, medusahead, jointed goatgrass reduction in cropland and rangeland
- Suppresses the growth of a grass weed allowing wheat and natives plants to grow


Competitive Advantages
- As a biocontrol for a specific weed to help increase wheat yields, restore rangeland and help in the fight to reduce wildfires
