What factors affect the consistancy of basified al sludge? Swim is tying to achieve a very granular form. This was achieved a few times, don't remember how though, definatly not on purpose. Could the temp during basification contribute to consistancy? Perhaps cooling the mix to near 0.c prior to basification would percipitate an easily filterable Muck with a coarse texture that would crash out quickly and easily filter? Does the speed of the 30% NaOh Addition affect consistancy or perhaps a different concentration of NaOH would do the job more affectivly? Any advise?
