The following offers a unique way to coagulate toxic waste from wastewater.

In Brief
|
|
|
|
A derivative of the plant whose root provides cocktail sauce with its pungent
|
|
taste can be used to remove toxic pollutants from wastewater.
|
|
|
|
Horseradish peroxidase PRECIPITATES aromatic amines, phenols and other
|
|
organic compounds from water. It changes these pollutants from a water-
|
|
soluble state to an insoluble or solid, form that's easily filtered out by
|
|
technicians.
|
|
|
|
"I'm convinced that the horseradish derivative will replace microbial
|
|
treatment in many places," says Alexander Klibanov, a professor of applied
|
|
biochemistry at MIT.
|
|
|
|
Wastewater now is often treated in large ponds, to which micro-organisms that
|
|
feed on organic compounds are added. Charcoal is then used to remove organic
|
|
compounds that the microbes pass up. But the micro-organisms are sensitive to
|
|
temperature, which makes them uncooperative during the winter.
