Filter Series MSCR PP

from 300 to 25 micron

 

TECNICHAL DATA:

  • Continuous flow rate during back wash
  • Filtration from 300 to 25 micron
  • Minimum water for cleaning

APPLICATION

  • Prefiltration for water treatment plants
  • Cooling towers
  • Heat exchangers
  • Irrigation
  • Protection of spray nozzle
  • Sea water filtration

 

OPERATION

Water enters the filter through the IN inlet and goes through the filtering cylinder from the inside to the outside. This will retain all non-deformable suspended solids that are the same size or bigger than the filtration degree installed. Filtered water leaves through the outlet pipe (OUT).

REGENERATION

The continuous settling of suspended solids inside the filtering cylinder obstructs the passage of water which results in a pressure difference (∆P). At a preset value of ∆P (range 0.3 ÷ 1 Bar) an automatic cycle will start to clean the filter cylinder .This operation begins with a signal that opens the discharge valve (2) and creates communication between the suction nozzles with the outside environment. At the same time, the electric motor (1) creates a rotating motion which enables the nozzles to inspect the filtering surface. Dirt is ejected through the discharge valve (2). The cleaning cycle lasts approximately 15 seconds.

CONTROL

A switchboard controls the washing phases. The signal that starts the cleaning cycle is given by a differential pressure switch. The switchboard gives an “alarm” signal in case of problems in the washing system. These signals can be sent to a pre-existing control centre. The washing phase can also be controlled manually. The solenoid controlling the valve is pneumatic.

DIMENSIONS AND TECHNICAL DATA


 

These technical data are indicative and subject to changing without notice.
The max suspended solids at inlet is an important factor, because depending on their size distribution and their specific weight they can clog up the filter in a different way
DURING THE REGENERATION PHASE THE PRESSURE DIFFERENCE BETWEEN THE PRESSURE GAUGE INSTALLED ON THE DISCHARGE VALVE AND THE OUTLET ONE MUST BE 0.5 / 1 BAR. SETTING THIS PRESSURE DIFFERENCE TO A HIGHER VALUE WILL ACCELERATE THE WEARING OUT OF INTERNAL PARTS.
