Hi all

we have filtered backwash sludge that is dewatered by centrifuge with the addition of polyelectrolyte. Sludge is expected to be 10-20% solids so we want to use progressive cavity pumps to send it to the containers.

Does anybody have any experience of pumping such sludge ? It is highly gelatinous and we are affraid of blockage
