Hello Thomas, i'm curious about the sediment...
Do you have a picture or fotograph you can send to me?
Thanks
Citando Thomas Kelly <[EMAIL PROTECTED]>:
Jim,
I appreciate the reply.
I am getting some of the antimicrobial stuff you suggested. Until then
I'm experimenting. I have found that a very small amount of the sediment
added to 250ml of clear BD ----> cloudy BD w. increasing sediment. This is
what makes me reasonably certain I have a microbe.
This morning I heated a 10L sample of the "contaminated" BD to 125F
(drying temp.) and another 10L sample to 150F. If sediment from these
samples does not "grow" in clear, uncontaminated BD, then I will assume that
the contaminant is killed/deactivated by these temps. I'll forego using the
"biocide" unless the problem rears its ugly head in my car or heating
system. I'll also be able to decontaminate my wash tank w. boiling water.
Good day to you,
Tom
