HydroCell - Automatic Backwashing Sand Media Filters
HydroFlo High Rate Automatic Backwashing Sand Media Filters are designed for general-purpose water filtration. These permanent media, automatic backwashing filters will remove organic and/or inorganic suspended solids down to 20 microns in size. 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 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. Single tank systems utilize unfiltered water for backwashing. Optional external backwash water sourcing systems are available for both single and multiple tank systems.
The standard HydroFlo single media sand filter utilizes a vertical side shell depth of 24”. Deep bed sand media filters featuring a 36” deep side shell are also available. HydroFlo sand media filters feature catalyzed epoxy linings, cast iron automatic valves, solid state automatic controls and type 304 stainless steel underdrains. Standard HydroFlo systems are shipped assembled on structural steel skids for easy installation and start-up. Standard inlet and outlet connections are flanged, but may be ordered grooved as an option.
HydroFlo in-line sand media filters are ideally suited for use in water re-use applications, water pre-treatment applications (for reverse osmosis and deionization systems, etc.) or as a pre-treatment prior to disposal bag or cartridge filters. In-line sand media filters are also widely used as primary filters for removal of suspended solids in incoming plant water or in wastewater clean up applications. Air scour and surface wash options are available if required.
