FILTRASCALE Automatic Backwash sea water filter for sea water desalination

Structure

 The Filtering Process   

The filter is equipped with a coarse screen that protects the finer screen from stones

and larger particles.

The coarse screen can be periodically clean manually. Automatic flushing of the fine screen is activated once the pressure differential (ΔP) in the filter reaches pre-determined value (up to 0.5 bar).

During the flushing cycle, the flushing valve opens, pressure is released from the hydraulic piston and debris lade water is discharged through the flushing valve.

Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered causing the dirt collector nozzles move along and rotate cleaning the whole internal screen surface. The flushing cycle takes 5 seconds.

The flushing valve closes at the end of the cycle, pressure reapplied to the piston, moving the nozzles back to their rest position, and the filter is cleaned.

During the whole process water supply is uninterrupted

Characteristics about the automatic self-cleaning filter   

1.simple structure.                    

2.filter traps does not need replacement

3.Shot anti-cleaning time, small loss in pressure and flow

4.Long useful life

5.Equipment can be connected with the central control system

6.High-precision filter

7.Applicable to different water quality

8.Few wearing parts, without supplies. Low operating

9.Continuous flow during automatic anti-washing

10.Action for automatic self –cleaning filter
