EM40A - VORTEX GRIT REMOVAL SYSTEM
| Application | Grit and oil removal from municipal and industrial waste water. |
| Characteristics | The system is made up of a turbine and an air-lift. |
| Operation | The water to be treated goes through the grit removal system with a tangential flow; the grit which sediments on the bottom is lifted by an air-lift. |
| Materials | Compact equipment in hot dip galvanized carbon steel or stainless steel. |
| Installation | In a concrete channel. |
| Tank diameter | From 1000 to 5000 mm. |
| Separation | Grit particles larger than 200 microns. |
| Advantages | The grit moved by the turbine is partially separated from the organic substances. |
| Disadvantages | Limited capacity of treatment. It does not include any oil removal system. |
| Optional | Blower |
OPERATION DESCRIPTION
The water flows into the grit removal tank in a tangential way and the blades keep the liquid in motion at any level of flow rate. The tangential flow and the blades rotation make the grit particles sediment on the bottom.
The grit is lifted by an air-lift and is conveyed to a mechanical separator or to a simple draining and filtering bed.
The grit removed is clean enough thanks to the separation of the organic substances due to the effect of the rotary blades.
Sometimes, to avoid the arising of decomposition phenomena due to the inevitable presence of organic material, a certain number of washings by water or air are necessary before extracting the grit.
This type of grit removal system does not separate any oily substances.
