The “EBS” filters range in flow-rates of up to 7200 m³/h (32000 US gpm), with screens designed ranging from 800-10 micron filtration degree. Inlet/Outlet flanges are available from 8”-36” diameter. The Filtering Process Raw water enters from the filter inlet (1) and passes through the screen (2). Clean water flows through the filter outlet (3). 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 screen. A pressure differential switch (4) senses the pressure differential and when it reaches a pre-set value, the cleaning process begins. The Self-Cleaning Process Cleaning of the filter is carried out by the suction scanner (5) which spirals across the screen, the open exhaust valves creates a high velocity suction stream at the nozzle tip which “vacuums” the filter cake from the screen. During the self-cleaning process, which takes approximately 30 seconds, filtered water continues to flow downstream. The Control System The “EBS” operation and cleaning cycle is controlled and monitored by a Programmable Logic Control (PLC). The PLC allows maximum flexibility in control options and has many features that can be incorporated per customer’s needs. During the self-cleaning cycle the PLC controls a solenoid that operates the exhaust valve by means of a hydraulic command or compressed air. The self-cleaning cycle begins under any one of the following conditions: 1. Receiving a signal from the Pressure Differential Switch 2. Time interval parameter set at the control board 3. Manual Start The control board also provides: Optional continuous flush mode Flush cycles counter Alarm output – may be used to open a bypass, shut-off a pump, etc. “EBS” Models Amiad’s “EBS” product-line consists of the following models: EBS-10000 for up to 1200 m³/h (5300 US gpm) EBS-15000 for up to 1800 m³/h (8000 US gpm) Mega EBS 40000 which consists of four EBS-10000 screen elements for up to 4800 m³/h (21100 US gpm) Mega EBS 60000 which consists of four EBS-15000 screen elements for up to 7200 m³/h (32000 US gpm) (1) (3) (2) (5) (4) amiad filtration solutions2135 (84") *2700 (106.3")1312 (51.6")600 (23.6")400 (15.7") EBS 10000 on-line EBS 15000 MEGA EBS 40000 *Approx. length required for maintenance Dim.
