MLSS sampling
MLSS sampling
(OP)
I need to select a very small dry pit pump that can be used to intermittently collect settled MLSS samples from a final clarifier of an activated sludge plant. The sampling line will be about 1.5 inches in diameter. What could be a good pump for this application?
Thanks in advance.

Popular PD pumps for low-shear applications include rotary types such as peristaltic, lobe, and eccentric disk pumps. In addition, diaphragm pumps belong to the reciprocating family, but like the three rotary types, are able to move product safely without shear.
The rotary lobe pump will probably be the least expensive.
i would keep the pump operating continuously; otherwise the solids will settle out and foul the piping.

One problematic issue that you may encounter in a wastewater treatment plant is debris and grit. Not sure what type of preliminary treatment that you have, but if you have any plastic debris or grit present, these materials may foul up or erode a pump.
