 How the Sigma Filter Works
General
The Amiad “Sigma” filter is an automatic filter, with multiple screens operated by a single hydraulic turbine mechanism.
With a capacity up to 120 m3
/h (528 gpm) and from 80-300 micron filtration degree. Inlet/Outlet connections are
100 mm (4”) diameter, and exhaust valve is 50 mm (2”).
The Filtration
Raw water enters from the filter inlet and passes through the multi-screens. Clean water flows through the filter
outlet. The gradual dirt buildup on the inner screen surface causes a filter cake to develop, with a corresponding
increase in the pressure differential across the multi-screens. A pressure differential switch (hydraulic or electric)
senses the pressure differential and when it reaches a pre-set value, the self-cleaning process begins.
The Control System
The “Sigma” operation and cleaning cycle is controlled and monitored by a hydraulic rinse control, or an electronic
battery /AC controller.
During the self-cleaning cycle the rinse control operates the exhaust valve by means of an hydraulic command, and
when the cycle is complete, it automatically closes the exhaust valve and waits for the next cycle. In the case of the
electronic controller, the self-cleaning cycle is triggered by the DP switch, then the AC or DC controller switches the
solenoid to open or close the exhaust valve by means of a hydraulic command, when cycle is complete, the controller
will shut the exhaust valve and wait for another cleaning command.
The self-cleaning cycle begins under any one of the following conditions:
1. Receiving a signal from the Pressure Differential Device - which is preset at 0.5 bar.
2. Time interval parameter set at the controller (electronic controller only).
3. Manual Start, triggered by 3 way ball valve or via electronic controller keypad.
The electronic controller also provides:
• Flush cycles counter
• Alerts output – low battery, DP cycle

How the Sigma Pro Filter Works

General
Amiad’s Sigma Pro is a multi-screen, polymeric filter that combines Amiad’s unique suction-scanning screen technology
with a compact design and an innovative self-cleaning mechanism. The filter capacity range is up to 280 m /h (1,233 gpm)
 3
and with filtration degrees from 80-500 micron. Inlet/outlet connections are available in 100 mm (4”), 150 mm (6”) and
200 mm (8”) diameter. Filters include a 50 mm (2”) exhaust valve.
The Filtration Process
Raw water enters through the filter inlet and passes through the multiple screens. Clean water flows through the
filter outlet. The gradual dirt buildup on the screens’ inner surface causes a filter cake to develop, which creates
an increase in the pressure differential across the filter system. A differential pressure (DP) switch (hydraulic or
electronic) senses the pressure differential and when it reaches a pre-set value, the self-cleaning process begins.

The Control System
The Sigma Pro operation and cleaning cycle is controlled and monitored by a hydraulic rinse controller or an electronic
controller. During the self-cleaning cycle, the rinse controller operates the exhaust valve by hydraulic command.
When the cleaning cycle is complete, the exhaust valve is automatically closed and is ready for the next cycle. With
an electronic controller, the self-cleaning cycle is triggered by the DP switch, then the AC or DC controller switches
the solenoid to open or close the exhaust valve by hydraulic command. When the self-cleaning cycle is complete, the
controller signals the exhaust valve to close and the system is ready for the next cleaning cycle.
The electronic controller also provides:
•Flush cycle counter
•Alerts – low battery, DP cycle

The Self-Cleaning Process
The self-cleaning cycle begins under any one of the following conditions:
1. Receiving a signal from the DP switch, preset at 0.5 bar (7 psi)
2. Time interval parameter set at the controller (electronic controller only)
3. Manual start, triggered by 3-way ball valve or via electronic controller keypad
The flush water flows through the hydraulic turbines, causing the suction-scanners to spin. The drop in pressure
forces the suction-scanners into an axial movement upward, ensuring that the nozzles sweep and clean the entire
inner side of the fine screens.
