I just spoke with a potential new supplier. He asked if I wanted my KOH in flake, beads, or liquid. I use flake in my bio-pro190. Can I use beads instead of flake in the 190?

You can use bead form of Naoh.. Seems as though the most common form of Koh is flake, ask the price difference if there is one.

reason for asking is new supplier said bead was 40% less cost.

I used beads once, they were much more difficult to dissolve than flakes, it took at least five times longer.

Sounds to me like he is confusing KOH and NaOH. KOH is flake and pricier, NaOH is beads and much less expensive. Did he (or you) say lye? Both are often called lye. Make sure you are discussing potassium hydroxide or sodium hydroxide, they are not the same. HTH

An out of the box question... Why use Koh that is pricier than naoh in a biopro?


My guess would be disposal of glycerin? Or a very cold garage.

using KOH you won't turn your processor into a soid mass of glop. I did that once when I first started out. then switched to KOH. I also read somewhere that KOH gives a more comlete conversion ? either way, good luck. Tom

in cold temps..say less than 40F

think solid vs a gel. even more so if methanol have been recovered.

Naoh glycerin will be solid at a higher temp the KOH glycerin

other thoughts

NaOH -- sodium based.. BAD for composting and water washing with dumping the water

KOH -- potassium based.. not so bad for composting and water washing with dumping the water. potassium is a fertilizer sodium is a plant killer.
