Sand separator

The grit separator is designed to concentrate the solid materials contained in the water coming for example from the collecting sump of a sedimentation tank. The grit separator consists of an inclined metal spiral, where the material to be cleaned arrives through a feeding hopper. Typically, the water containing solid particles to be separated is introduced into the hopper by one or more extraction pumps that operate at interval suitable for the amounts of solids to be removed. In that case, the grit separator is synchronized with the feeding pumps. As the solids are conveyed by the screw upwards, water flows away. Once the screw length has been covered, the concentrated solids are discharged to a container for future disposal. The grit separator can operate both in manual and/or automatic mode, through control from the electrical panel according to the operating needs.
