Filter Backwash Automation

Backwash automation system for filters.

PLUVITRON® control panel has the purpose of facilitating and ensuring that whatever are the conditions of the raw water, the backwash operation will be performed within the safety limits.

The time based control panels operate regardless the characteristics of the raw water. They perform the backwash always at the same time of the day, so a precipitated backwash could happen, before the total saturation of the filters, or a late one with the filters already saturated and with high head loss.

PLUVITRON® operates based on the differential pressure switch. Backwash will only occur when the filter head loss reaches a preset value, providing water and energy economy.

For convenience, PLUVITRON® is supplied with all required components for a fast and accurate assembly: disc pre filter, solenoids and a mounting structure; the assembler only need to connect the 8 mm micro tube to the three way valves.

  • Backwashing process:
The backwash process is carried out by the control unit which sends a signal to the solenoids when the preset head loss is reached. These solenoids send a hydraulic signal that opens the backwash valves, reversing the flow and removing contaminants deposited in the sand.

For manual backwash, simply activate the 3-way valve on the backwash valve lid, or the corresponding button on the control panel.
