Abstract
A sludge de-watering plant has a plurality of filter presses connected in parallel with at least two low-pressure pumps delivering a high rate of sludge for rapid filling of the presses and at least two high-pressure pumps substantially effecting the filtration. A particular pipe system is associated with each of the low-pressure and high-pressure pumps with the pipe systems being connected to the individual filter presses for mutually independent delivery. Control means mutually controls the pumps in the two pipe systems independently by the relevant pressure in the pipe systems.
