Multi-Media Filters
Equipment Overview
 Hydro-Flo
Automatic Backwashing Multi-Media Filters are designed for enhanced
water quality filtration. These permanent media automatic
backwashing filters will remove organic and/or inorganic suspended
solids down to 5 microns and below in size and will entrap greater
amounts of suspended solids contaminants than sand media filters.
Through the use of automatically controlled backwashing, the filter
will operate "on-line" for extended periods of time prior to the
short backwashing cycle. Automatic filter operation is monitored on
both elapsed time as well as pressure differential. When the
controller "calls" for a backwash as a result of pressure
differential or elapsed time, the backwashing function utilizes a
portion of the clean filtered water produced by the system to clean
the media bed. Single tank systems utilize unfiltered water for
backwashing. Optional external backwash water sourcing systems are
available for both single and multiple tank systems.
 The
Hydro-Flo Multi-Media Filter utilizes a vertical side shell depth of
60" with layered graded beds of filtration media. Through the use of
multiple layers of specially selected filter media, "progressive
filtration" is achieved through the media layers. The first layer of
filter media entraps and holds larger sized particles allowing
smaller particles to be removed in subsequent media layers. The
final media layer "polishes" the water removing suspended solids
down to 5 microns in size and smaller
Hydro-Flo Multi-Media Filters are ideally
suited for use where stringent water quality standards are required
or where higher levels of suspended solids are present. These
applications can include water re-use applications, water
pre-treatment applications for reverse osmosis and de-ionization
systems, or as a pre-treatment system prior to disposable bag or
cartridge filters. Hydro-Flo Multi-Media Filters are also widely
used as primary filters for removal of suspended solids in incoming
plant water or in waste water clean up applications. Air scour and
surface wash options are available if required. |
