ROTATING DISTRIBUTORS
FOR PERCOLATOR BEDS
The distribution of the sewage on the surface of the percolators beds can be made, on request, by rotating distributors as following:
- by gravity, when the rotating movement is assured by hydraulic head of out going sewage;
- motorized by central traction;
- motorized by tip traction.
Arm size, nozzle type and number are calculated, each time, upon flow rate of treatment and rate of pre treatment that is submitted, the sewage to be distributed and the area of the percolator bed.
It is possible to add other apparatus to the plant, both to recycle the sewage as to maintain the best rate of moisture in the bed and to clean the nozzles.
