2 page 2 How the FILTOMAT MCFM Filters Work General Amiad s FILTOMAT MCFM filters are automatic filters with an optional contuous self-cleang mechanism designed for high flow rates and heavy dirt loads of fibrous and sticky particles. With their 8000/12000 cm² three types of screens the MCFM models support flow-rates of up to 750 m³/h (3300 gpm), filtration degrees of 3000 down to 15 micron and let/outlet diameters of The filtration process begs when raw water flows to the Filter Inlet (1) and through the Coarse Screen (2). Here, the water is pre-filtered order to protect the cleang mechanism from large debris. The water then passes on the ner surface of the Fe Screen; dirt particles are trapped and accumulate side the filter while clean water flows out of the Filter Outlet (7). The Self-Cleang Process The self-cleang process of the MCFM filters is operated by a prograable logic controller (PLC). The PLC algorithm shifts the cleang process, back and forth, between the followg modes accordg to the actual real-time dirt-load on the filter: 1. Pressure Differential and/or Time Interval This mode is active consistent, moderate dirt-load conditions. The cleang process is activated accordg to the readg of the pressure differential across the filter s screen or by a pre-set time terval. 2. Contuous Flushg This mode is active persistent high dirt loads conditions. The cleang process is constantly active and the filter s PLC controls its tensity. ( 3. Super Flush This mode is active when the Contues Flushg mode is not sufficient to mata a proper low pressure differential across the screen. A secondary Super Flush Valve (13) is activated to crease the suction force across the screen durg flushg. 4. Reduced Flow This mode is active (mostly momentary) when the Super Flush mode is not sufficient to mata a proper low pressure differential across the screen. The flow of water through the filter s outlet is reduced and therefore the pressure the filter is creased, this enables the cleang mechanism to cope with the exceptional momentary heavy dirt-load. The self-cleang process contuously releases a small quantity of water to the atmosphere through the Flush Valve (9), creatg a steady back-flush stream through the Fe Screen (6) the Nozzles (5), the Collector Pipe (4), the Dra Chamber (8) and out of the filter through the flush valve. The back-flush stream creates a reverse flow at the nozzles, generatg a spot cleang of the fe screen ner surface. The Electrical Motor (3) rotates the Collector Pipe and the nozzles, while the Piston (12) moves the collector pipe back and forth. This spiral movement of the collector pipe ensures that the suction nozzles sweep the entire ner surface of the fe screen. Sce the MCFM is designed for handlg heavy dirt loads of fibers and sticky particles, a high pressure jet stream Injection Nozzle (11) is corporated with the cleang mechanism adjacent to each suction nozzle. The Booster Pump (10) ject high pressure jet stream of filtered water through these nozzles, durg the self-cleang process, onto the fe screen; enablg the removal of sticky materials from the screen.
