How the Sigma Filter Works General The Amiad Sigma Filters are automatic filters, with multiple screens operated by a single hydraulic turbine mechanism, with a capacity up to 280 m 3 /h (1,232 gpm) and from 80-300 micron filtration degree. Inlet/Outlet connections available: 100 mm (4 ), 150 mm (6 ), mm (8 ) diameter, and exhaust valve is 50 mm (2 ). The Filtration Process 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 screen inner 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 (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 electronic controller also provides: Flush cycles counter Alerts output low battery, DP cycle Sigma models Amiad s Sigma Series consists of the following models: Sigma 4 - for up-to 120 m 3 /h (528 gpm) Sigma 6 - for up-to 180 m 3 /h (792 gpm) Sigma 8 - for up-to 280 m 3 /h (1,233 gpm)
