Ole Bob, Marshall, Ode, Trem, Mike, Silver Friends One and All,
I need help in understanding why my generator for concentrated CS is
outputting very low ppm.  Can somebody help?  Today I did a first trial
run of an automated switching device, for the generator shown at
http://www.purifier.com.np/CS.html   This is to make the concentrated CS
needed for saturation of ceramic water purifiers.  Unfortunately the
electronic engineers didn't quite get the device right, so there are big
disparities in the times between the two electrodes.  i.e. I wanted to
reverse poles every minute, but at that setting it's 60 seconds at one
electrode and 45 at the other.  So I chose the lowest setting, where the
percentage disparity is lowest, one electrode 23 seconds and the other
28.  Could the short period between reversals be giving less ionic
silver per time?

One puzzling aspect is that the appearance of the CS seems to be the
same as for the really concentrated stuff, bright red to transmitted
light, but so dark that it appears gray unless a bright light is shined
through.  I diluted 9:1, expecting I'd need to do this to get within the
range of the Hanna Instruments PWT, but ended up with only 2.4 uS.
Checking the 'concentrated' stuff I get 24 uS.  But this certainly
doesn't resemble any other 24 to 30 ppm I've ever seen.  At 9:1 the 2.4
uS is bright orange.  Could this be very low ppm of big particles, thus
the bright orange?  Or am I just doing something wrong?  Could I be
misinterpreting the use of the PWT.  It's also puzzling that there is a
very strong Tyndall Effect, the solution emanating a kind of pearly
iridescence.
Thanks in advance.
Reid
