MODELS SCREENING EQUIPMENT
EM31C - AUTOMATIC INCLINED FINE SCREENWITH FIXED BASKET AND SCREW COMPACTOR
| Application | Screening of civil and industrial waste water. Screening of process water within industrial cycles. |
| Characteristics | The machine is equipped with a fixed basket made of trapezoidal bars or perforated plate, a lifting screw with cleaning brushes, a compactor and a washing system for the screened material. |
| Operation | The waste water containing suspended particles goes through the filtering basket which holds the material in suspension. This material is lifted and removed by a screw equipped with cleaning brushes on the profile in contact with the basket. The screened material is washed by washing ramps, located in three different positions. |
| Materials | Compact machine: stainless steel. |
| Installation | In a concrete or stainless steel channel |
| Channel width | From 370 to 750 mm. |
| Degree of filtration | From 0.5 to 10 mm. |
| Advantages | Continuous filtration, suitable even for water containing filaments of fibers. |
| Disadvantages | Not suitable to remove solid materials larger than 250 mm |
OPERATION DESCRIPTION
The machine operation is controlled by a Pause-ON timer.
If the water level upstream the filtering screen should increase and exceed a pre-set threshold, a level measurer can start the machine, even during the pause phase.
The water to be treated is filtered by the fixed basket and the solids held are lifted, compacted and discharged by a screw.
During the lifting, the screened material is washed to remove the soluble organic substances.
