BMF Series Media Filter Operating & Maintenance Manual Process Efficiency Products (“PEP Filters”) filtration equipment has been designed to give long, trouble-free service when properly installed, operated and maintained. This manual contains important installation procedures and should be read prior to installing. This manual is also a guide for proper filter operation, maintenance and winterizing.
BMF Series Media Filter Operating & Maintenance Manual General Description The BMF Series Industrial Water Filters are permanent media type units specifically designed to clean cooling tower and other industrial process water. The filters may be used for both side-stream and full stream applications in pressurized and nonpressurized systems. Standard BMF series filter vessels are rated for 50 psig (345 kpa). Optional higher pressure ratings of 100 psig (689 kpa) and 150 psig (1034 kpa) are also available.
BMF Series Media Filter Operating & Maintenance Manual Connect a backwash waste line to the connection labeled "Waste". This line carries the backwash wastewater to drain. Do not install a valve in the waste line. Refer to Table 3 for the minimum and maximum backwash flow rates. Note: If the drain is not large enough to handle the volume of water during backwash, it may be necessary to use a backwash water holding tank to buffer the backwash flow rate from the filter to the waste drain.

Any air leaks in the pump suction piping must be found and repaired. Failure to do so could result in poor performance and/or personal injury. 11. Backwash the filter. After backwashing the filter, check the pressure gauge on top of the filter tank and record the clean media operating pressure gauge (inlet gauge).
BMF Series Media Filter Operating & Maintenance Manual Maintenance Procedures Pump Pre-strainer (if equipped) Warning: Disconnect all electrical power prior to performing pump maintenance. The filter pre-strainer basket on the pump inlet must be checked regularly and kept free of debris. Failure to do so may damage the pump and/or motor. Shut off the power, close the valves, open the manual air relief valve, remove bolts and the pre-strainer cover.
BMF Series Media Filter Operating & Maintenance Manual Water Treatment Filtration is an effective way of reducing and managing the level of contamination in a fluid system. Still, there are other components of equal importance in a water treatment program. For cooling tower water and closed loop systems, often the water must be further treated to inhibit or prevent the deposition of dissolved solids on heat transfer surfaces.
