3.4 Functional description
The unfiltered raw water flows into the filter from the inlet side and then from the inside out
through the filter element and to the pure water outlet.
Thus, foreign particles of > 100 µm in size are retained.
Depending on their size and weight, the foreign particles stick to the filter element or they fall
straight down into the filter funnel.
If the permissible differential pressure of 0.4 bar is exceeded, backwashing must be
carried out. The differential pressure can be read off the pressure gauges.
The drain is opened by turning the backwash handwheel to the right as far as it will go, and
backwashing is carried out.
When the backwash handwheel is turned, the brush rotates with the backwash handwheel
and sweeps over the filter surface of the filter element. The filter element is cleaned.
The impurities are removed by the brush and the suction nozzle sucks them into the drain
outlet.
The drain outlet is closed by turning the backwash handwheel to the left as far as it will go,
and the backwashing process is terminated.
