EM42 - DETRITOR TYPE GRIT REMOVAL SYSTEM
| Application | Grit removal from municipal and industrial waste water. |
| Characteristics | The system is equipped with baffles and grit scrapers. |
| Operation | The water to be treated goes through the grit removal system with a laminar flow; the grit which sediments on the bottom is conveyed to the sides and evacuated by an air-lift. |
| Materials | Compact equipment in hot dip galvanized carbon steel or stainless steel. |
| Installation | In a concrete tank. |
| Tank diameter | From 2000 to 16000 mm. |
| Separation | Grit particles larger than 200 microns. |
| Optional | Air-lift for grit evacuation |
OPERATION DESCRIPTION
The water flows into the grit removal tank from the side. The water flow must have a laminar motion.
The baffles placed at the entry are installed in such a way to distribute the water homogeneously, all over the tank width.
The grit which sediments on the bottom is scraped and conveyed to the periphery of the tank where it is lifted and evacuated by an air-lift.
The average water level in the tank is 700-1000 mm.
