Fabricating Flow Recycle System #3

Open JC-Conneely opened 6 years ago

JC-Conneely commented 6 years ago

We placed an order for PVC glue/pipe cement, and are waiting for it to arrive to start fabrication. We are in the process of drawing up designs for the new sed tank now.

This upcoming Tuesday, we plan to ask the machine lab folks if it would make more sense for us to drill and tap the sed tank given the size of the PVC pipe and the size of the flow recycle line.

@monroews We are currently in the process of drawing up a design for our flow recycle line. Do you think that the side of the sed tank we attach the recycle line to will affect our results, based on the hypothetical model you ran? Thank you!

I think the glue arrived on Friday. It is likely in the main office. Share a sketch of how you want to connect the recycle line. You might put a Tee in the inlet tube to the sed tank and attach it that way for now. The recycle line should connect part way up the tube settler. Your goal is to have a source of concentrated flocs that you recycle to the bottom of the sed tank.

@monroews recycle line sketch This is a rough sketch of what we were picturing. We were unsure if the recycle line should be above or below the floc weir, or even if it might make more sense for it to be at the very top of the recirculator on the opposite side.

Excellent. The recycle line should be below the floc weir (as you have drawn it) because your goal is to have as high a concentration as possible in the floc recycle. Above the floc weir there aren't many flocs if the system is working correctly. I would probably move the recycle line to half way between the the bend in the tank and the floc weir. I'm eager to see what happens when you run this!
