Introduction
Amiad filtration equipment has been designed to give long term, 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. It is important that maintenance personnel review this manual carefully, including the
Safety Precautions and Warnings before performing any maintenance on this sand media water filter.
Note that the recommendations on the frequency service are minimums, and where operating
conditions are severe, the service should be performed more often. For each required service, follow
the procedures outlined under the Maintenance Procedures section in this manual. If additional
information beyond the scope of this manual is required, contact your local Amiad Representative or
the factory.
General Description
The BMF Series Sand Media Filters are permanent media type units specifically designed to clean
process water. The filters may be used for both side-stream and full stream applications in pressurized
and non-pressurized systems. Standard BMF series filter vessels are rated for 100 PSI for the 54” thru
96” tanks. All pressure ratings are based on a maximum temperature of 100 degrees Fahrenheit.
Amiad can provide tanks with higher pressure ratings, as well as ASME Code design and construction.
Please contact the factory for details and pricing.
Filter Operation
Water from the system is pumped through the over-drain assembly at the top of the filter tank and
distributed evenly over the media. Unfiltered water flows downward through the filter media where
suspended particles are trapped. The filtered water then passes through the vessel and out the
under-drain assembly at the bottom of the filter and returns to the system.
When the trapped particles cause the pressure differential across the media bed to reach a pre-
determined pressure of approximately 16 PSI flow is reversed through the tank by repositioning the
valves automatically or manually. The media is backwashed with a rigorous scouring action, releasing
trapped particles within the media. The dirty water passes from the filter vessel through the over-
drain assembly at the top of the vessel and flows to drain. After the backwash cycle (field adjustable
and factory pre-set at 2 minutes), the filter valves are again repositioned and the filtration cycle is
resumed.
Installation
CAUTION!!!
Water sources vary and may contain impurities that can adversely affect a filter
system. Minerals, biological microbes and other impurities must be identified and addressed by each
user on a case-by-case basis. Contact your filtration system dealer or the factory for additional
information and recommendations.
Please review installation and operations manuals of individual parts within the system. This manual
may not cover all processes and/or procedures of these parts.
Unpacking
When the Amiad BMF Media Filter is delivered to the jobsite, it should be inspected thoroughly to
ensure that all required items have been received and that filter equipment is free of any damage that
may have occurred in transit. Any damage must be noted on the bill of lading at the time of receipt.
Without this, there is no recourse to recover the cost of damaged goods. The filter model number
appears on a nameplate located on the unit and should be checked against the invoice/packing list.
