When the sector is placed in the backwash chamber, this remains watertight due to the nylon
bristles, for this reason, when the backwashing valve is opened, water flows through the filtration screen
in the opposite sense than the filtration process which means an important saving in backwashing water
consumption.
An electronic system protects mechanically the equipment. It is composed of an electronic torque
limiter, a progressive starting system and a crown position electronic control.
In the case that any foreign object blocks the screen rotation, the system inverts the rotation
alternatively until the foreign object is removed. In case it is too big, it will be extracted manually. An
alarm signal will turn on if any system failure occurs.
Performance
FIRST STARTING UP:
The pipe has to be object-free. The filter rotation has to be initiated before there is water flow in
the pipe.
COMMON PERFORMANCE:
When water flows through the filter, the dirt particles that are bigger than the filtration degree get
retained on the screen. These particles produce an increase on the differential pressure. If this differential
is not larger than 0.8 m.c.a, the filter backwashes according to the default time interval (8 hours,
variable). If the the scale 0.8 m.c.a. is not exceeded, the differential pressure system detects the same
one and the backwashing cycle starts.
