micro algae concentration
Hi George,
how many RPMs would be needed to spin them down? I was
considering somthing along the lines of a washing machine motor and 5
gallon buckets to do the volume that I would need to process. After giving
it a bit of doing inhte head it doesn't seem to reasonable. Perhaps
settling a nonmotile species wihtout somthering it.... Any ideas?
