Pugle,
Overall, you can tell it is the same design in principles. A few modifications and tweaks here and there to adjust for "the stuff we have" is just the nature of DIY, don't you agree?
When I saw Mr1SUPERBs videos on this sieve filter design, I immediately wanted to put one together. I thought that it was an exceptional design. However, I also like to "tinker".
It was my desire to accomplish several filtration tasks in one 55 gallon barrel. So, I dreamed up some modifications of my own.
I wanted to try a cone-shaped "umbrella" for the SS mesh strainer portion and have the solids roll off the bottom of the cone into ten filter socks set in a circular pattern around the
inside perimeter of a 55 gallon barrel. I was going to have the influent water come up through the center of the cone like a (gentle) volcano and spill out over the whole outer surface
of the SS mesh cone. I bought 300 micron SS mesh for the cone (instead of the 100 micron that Mr1 stated). It was less expensive and I thought that it would clog less. Especially
if any algae or bacteria colonies happened to attach themselves to it.
I did some very crude testing of the SS mesh in my kitchen lab and discovered something that I didn't like very well about this design. Because of the capillary action of the mesh and the adhesive/cohesive quality and surface tension of water, the water seemed to want to follow or hug the inside of the mesh down its length rather than dropping or flowing straight
through the mesh.
I wanted it to waterfall straight down through the mesh cone into the open center of the barrel moreso and leave just a minor flow over the outside of the cone for washing the solids into the filter socks. My tests didn't seem to provide me with sufficient evidence that it would operate this way with the limited space and angles allowed. My impression was that I either needed a much larger cone with longer sides (which I didn't have space for). Or, I was going to have to forcefully direct the water at the sides of the cone to push it through the SS mesh (which I thought would cause some smaller debris to be packed into the mesh and become trapped, build up and eventually clog).
The inverted SS cone sieve design looks really interesting and hopeful on paper, but if it doesn't work it isn't worth the time and expense to fabricate a prototype to prove that. I am fairly assured that, because of the geometry and the size that I desire, it won't work. It would work for a much larger vessel, but then I am defeating my original goals and just changing my design anyway, so I might as well go a different route right off the bat.
But, I am still pondering something a little different here. It keeps me trying, you understand. It is what makes this part of the DIY thing "FUN" for me.
