Hydrolase work better with oxidizer present, thus the electrolytic oxidation as it is not limited by the organic load.<br><br>The bonds are no more or less stable then those found in manufacture of pyrine and organochloride pesticides/herbicides.<br><br>If the sludge is dried - then direct application of catalytic hdyrolase enzymes with a small solution of hydrogen perodixe will also work - this is accomplished by soaking the sludge where applied - or if winrowed - then spraying, turning, and spraying again.<br><br>Orenda Technologies - orendatech@earthlink.net probably has data and application info - <br>DaveFri, 10 Mar 2006 13:33:32 GMTEOH2Ohttp://www.wef.org/TechnicalDiscussions/Topic1253-20-1.aspxOlder sludge in our lagoons contains dioxins and furans remaining from previous pulp and paper processes during the 70's. I've heard that solar radiation can help breakdown these organic compounds with time. Does anyone know if there has been research done or if there are proven technologies to help remediate dioxin/furan laden sludge?</P><P>NeilThu, 09 Mar 2006 12:13:10 GMTneil.mclaughlin
