Descrição
Given the flow to be treated ans the geometric characteristics of the trickling filter, calculates the diameters of the pipes in the equipment, the head losses and, in the case of motorized arms, the power of the electric motor.
| Identifier | Meaning | Note |
|---|---|---|
| A | Internal diameter of the filter | |
| B | Feed pressure | Reference value: 1.5m |
| C | Overflow height | Recommended value: 2.00m |
| D | Freeboard height | Recommended value: 0.15m |
| E | Column height | Recommended value: 0.17m |
| F | Central column diameter |
Observações
- Standard number of columns: 4;
- Calculation made for hydraulic actuation, however, if electrical actuation is needed, the required commercial power is provided.
