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.
