- Here's a link to a very impressive
video by the SmartFlow Tech people:I have handled enough algae paste
to know that this is real. I called
them on two consecutive days to see what
they charge for their solution. Nobody
was in Sales either time, and they did
not return my call.
Their use of the term 'permeate' to
indicate the filtered cell-free medium
tells me that they are using a membrane
microfilter. If so, the system should
be pretty cheap. Here's a link to a
video that explains a bit more about the

a Culligan reverse osmosis filter unit.
I don't remewmber when or where I got
it, but I plan to hang onto it until I
can run a test with it to see what it
can do for us. Replacement filters for
this kind of unit run about $15.00.
Rather than using a reverse osmosis
membrane filter, I am thinking that a
5-micron polypropylene sediment filter
might be more appropriate to the task,
and these only cost about $7.00.In 2008, when we went to a SCORE
conference for SBA counselling, the
counsellor who was assigned us had
prior experience doing research with
algae. In 1975, he was using membrane
filters to harvest the algae. He said
that membrane technology had improved
a lot, since then, and recommended
membrane filtration for our enterprise.
