Less commonly, more specialist dewatering methods are used in open pit mines. The can include lines of wellpoints or eductor wells used to stabilize fine grained granular deposits (silts or sands) where they are exposed in the pit slopes, or drainage tunnels and adits driven near the open pit to promote drainage in fissured rocks of low hydraulic conductivity.

Digestate Processing

DIGESTATE PROCESSING Whole digestate may be applied directly to land however dewatering or further processing of digestates may be necessary in certain situations. Dewatering separates the material into two fractions: a solid fraction (typically 25-35% dry matter) which can be used as a soil improver and a liquid fraction (typically ≤ 6% DM) that can be used as a liquid fertiliser.
