Anyone doing sawdust washing with potassium hydroxide?
I'm just wondering if the liquid soaps filter out as well as the solid.
I use KOH with sawdust and it works very well.
Have been using it for a couple of years.
I thought it was probably the case, but it's good to know before I build a process around it
Do you demeth before going thru the sawdust?
You settle and drain the glycerol before?
I was wondering to pass the bio as soon as the process ends thru the sawdust towers, (gravity flow) before settling and draining the glycerol to avoid the long settling time. I know it will clog fast but...
Sawdust is cheap!
After that pass it thru my 2 micron and finally to my purolite towers.
