Deep Bed Sand Filters
HydroFloTech HydroCell “Deep bed” Sand Filters are designed for general-purpose water filtration. 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 HydroCell filter utilizes a vertical side shell design with a diameter of 24”. Optional 36” diameter designs are also available. HydroFloTech HydroCell Media filters feature catalyzed epoxy linings, cast iron automatic valves, solid state automatic controls and type 304 stainless steel underdrains. Standard HydroCell Media Filter 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. Air scour and surface wash options are available if required.
