GRIT REMOVING AND DEGREASING

Grit removing, deoiling and degreasing is a treatment carried out after the fine screening process. The objective is to send the effluents into tanks / basins allowing the reduction of flow velocities thus making deposit / decant the sands and float the grease. In the case of combined units, the injection of micro-air bubbles allows acceleration of the flotation of fat. In the majority of cases, the sands are extracted and conveyed by an Archimedes’ screw and the greases are scraped at the surface.

OUR GRIT REMOVAL & DEGREASING EQUIPMENT

EQUIP GRIT is used to remove grit from water. These separators consist of a shaft less screw conveyor provided with a big sedimentation hopper, including inlet/outlet flanged spouts. Effluent flows through the hopper, that is designed specifically to allow the sedimentation process while the grit separation takes place. The shaft less screw extracts the grits from the hopper’s bottom, while the cleaned water outflow trough the outlet spout. The water enters the hopper and the sand falls on the bottom, to then be extracted from the cochlea that, by rotating at low speed, avoiding turbulence and increases the efficiency of the process.

Grit Classifier - EQUIP GRIT

EQUIP GRIT is used for the separation and cleaning of sandy material from wastewater. These machines consist of a conical decantation hopper, provided with an agitation system that give to sandy waste water a rotational movement; this rotation facilitates the sedimentation process and, at the same time, keeps in suspension the organic matters. The hopper’s bottom is fed with clean water that creates a counterflow that removes the organic material which is then evacuated from a pipe placed at the upper side of the hopper.

Grit Washer - EQUIP GRIT

MINI UNIT is a combined equipment for screenings and grit removing; it represents the most economical solution to treat low flow rates. The incoming wastewater is filtered through a screw screen than goes into the settling tank. The internal baffle system allows an efficient separation of the sand that is collected on the bottom of the tank and extract with a screw.

Screening and Grit Removing - MINI UNIT

LARGE UNIT is a sand classifier with longitudinal hopper that makes a selection of the grit for the principle of gravity and thanks to the whirling motion created by blower, moving the particles, separates the grit from the organic material that due to major specific weight respect to the water decants on the bottom of the hopper, where there is a bottom screw that carries the grit in a collection tank; also bring in suspension oil and grease. An inclined, called extractor, pick up the grit and bring it out of the machine. The grease removal system is made from a series of plate moved by chain that scrapes the water and brings the grease in a collection hopper. The water rich of organic material exits to the machine for overflow from an appropriate discharge.
