Hi All,
I'm working with a municipality who has a few typical submersible wastewater pump stations that have ragging problems. The controls use good old-fashioned relay logic with float switches.
These stations have very bad ragging problems. We have plans for a grinder at the upstream station that collects the rags before pumping down the line to the other two, but it's probably at best a year away.
The immediate problem seems to be the rags collecting on the float switches. Recently a float laden with rags became tangled with another float and caused some issues.
Due to the hatches that are barely large enough to pull the pumps there isn't much room between the floats.
I was wondering if maybe installing a float tree, where all of the floats are in-line vertically, would help avoid tangles caused by the debris floating around in the wet wells.
Has anyone had any experience in a situation like this they could lend?
Thanks,
Mike
