Early research at Southern Illinois University in Carbondale, IL, found the
zebra mussel removes solids and some nutrients from diluted liquid swine
manure.
The researchers found a 90% improvement in the amount of suspended solids
in the liquid manure. The mussels also appeared to reduce odor.
The zebra mussel, considered a detriment to freshwater ecosystems, is a
natural water filter. It constantly pulls water through its body, filtering
out nutrients it needs to live. The remaining particles are coated in a
mucus-like film called pseudofeces, which settle out of the water.
Researchers now are trying to determine if the mussels or the pseudofeces
have value as a plant nutrient. Researchers also are looking at how to
include the mussels in a waste-treatment system.

As I begin this week's column, I"m reminded of two different "flip side" statements that may help characterize the topic at hand. The first is the old Archie Campbell schtick - "That's good - no that’s bad," which I have used before. The second reflects President Truman's frustration with economists' incessant use of the qualifier - "on the other hand" - to introduce the contrary opinion on a given topic. President Truman once demanded in his usual colorful language: "Will someone please find me a *!&%$*?>
