Yardney Sand Media Filters are designed as a solution for the most challenging dirty water conditions in irrigation systems. Yardney pioneered the use of sand media filtration in 1965 and through advancing technology, continues to provide high performance and long term value in the field. Yardney Sand Media filters are manufactured in the USA to the most exacting standards.
Offered in multiple configurations and available in standard design and pressures or one of the many alternative designs in both Carbon Steel or Stainless steel which include High Pressure, Interior Epoxy coating, removable under drains, etc.
Standard product includes:
The automatically controlled system 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. The backwash flow is segregated for proper disposal in a separate discharge line. Note that single tank systems utilize unfiltered water for backwashing. Optional external backwash water sourcing systems are available for both single and multiple tank systems.
Superior filter performance is achieved by the added features of a larger inlet, two-stage deflector, 14" media bed depth, gravel pack and a hydraulically balanced underdrain to produce a low pressure drop which will produce longer run times between backwashes.
Superior backwash performance is achieved by the use of a hydraulically balanced under-drain and gravel which produces the proper lift and fluidization of the sand media bed to ensure complete release of entrapped particles which will produce a low pressure drop and longer run-times between backwashes.
