How does the "MEGA EBS" filter work ?

The Mega EBS is an automatic self-cleaning water filter that is designed to work with various types of screens in filtration degrees from 800 to 10 micron, and is available in 16", 18", 20" and 24" inlet/outlet diameter.

Filtering process

The water flows through four stainless steel cylindrical filter elements from inside out, creating minimal head loss. Different types of screens are available for different filtration needs.
The "filtration cake" accumulating on the screen surface causes head loss to develop across the screen. When this head loss reaches a preset value, the cleaning mechanism is operated.

Self-cleaning process

There are four independent cleaning mechanisms for each screen elements. Each cleaning mechanism incorporates a stainless steel suction scanner driven by a 1/2 HP motor. The scanner's hollow nozzles scan the screen surface in a spiral motion, without touching the screen. Suction power is achieved due to low pressure consitions created by the exhaust valve opening to the atmosphere. The filter cake is then discharged through the open exhaust valve. Cleaning takes between 35 to 40 seconds. The self-cleaning process begins when the pressure differential across the screen reaches a pre-set value or a predetermined lapse of time. During the self-cleaning process filtered water continues to flow downstream of the filter.

Control system

The Mega EBS filter is equiped with a pressure differential switch that transmits an electrical signal to the electronic board, which initiates the flushing cycle.
Four solenoid valves operate the exhaust valves by means of a hydraulic command or compressed air.

Features

  • Flushing according the pressure differential and/or according to time
  • Option for operation of continuous flushing
  • Flushing counter
  • An alarm or an alternative reaction in malfunction mode (open a bypass, shut-off a pump, operate an alarm signal in control room, etc.)
  • Flushing can be set to operate in single mode, one filter element is flushing at one time, double mode - two filter elements are flushing at one time, or in full mode - all four filter elements are flushing simultaneously.
