Multi Media

Yardney Multi-Media filters are designed for enhanced water quality filtration for the removal of organic and inorganic suspended solids down to 5 microns. Multi-Media filters may be used as a stand-alone system or in conjunction with or as a pretreatment for other filtration technologies. The Multi-Media filtration systems utilize a vertical side shell depth of 60" with accompanied reverse stacked medias for progressive filtration through the filtration system. All Yardney industrial media filters utilize our simple backwash system for ease of operation and consistent water quality.


Yardney industrial filtration systems are shipped as a complete, finished, assembled and packaged unit. Each system is skid mounted with tanks, valves, manifolds, controller, tubing, electrical solenoids and removable underdrain assembled and ready for water source and power hookup.


Performance levels can be modified to remove suspended solids of a given size range consistent with desired application objectives.

Applications

  • Removal of organic and/or inorganic suspended solids down to 5 microns with enhanced solids capacity vs. single media sand filtration
  • Storm water runoff, industrial process water, incoming plant water, waste water clean-up, industrial water for plant reuse
  • Pre-filtration in applications such as granular activated carbon, reverse osmosis, cartridge or bag filtration and deionized water
  • 100 psi standard operating pressure (high pressure systems available)
  • Flow ranges from 10 gpm and up

Advantages

  • State of the art fabrication provides added strength under pressure and long system life
  • ASME code shaped head construction for durability and safety
  • Stainless steel wedgewire underdrain
    • Ensures structural integrity in the harshest conditions
    • Hydraulically balanced to increase effectiveness of backwash while reducing flush frequency and waste of water
    • High strength stainless steel wedgewire will withstand a collapse pressure in excess of 600 psi
  • Standard carbon steel products use 3/16" thick material
  • Backwash automatically initiated by elapsed time, pressure differential or time stamp with Synergy controller
  • Easy-entry lid closure with weld tabs for operator safety
  • Available in welded carbon steel
  • 3M Scotchkote® 134 fusion bonded epoxy coating on interior surfaces
  • Made in USA

Standard Assembly Includes

  • Fully assembled for easy installation
  • Skid mounted
  • Backwash Valves
  • Inlet, outlet and backwash manifolds
  • Controller, solenoids, electrical wire, tubing
  • Removable underdrain
  • 3M Scotchkote® 134 fusion bonded epoxy coating on interior surfaces

Available Options

  •  ASME code
  • High pressure
  • Solar package
  • PLC controller
  • Custom filter station layout piping
  • Air scour
  • Continuous flow
  • Rinse to waste

Filtration Process

Filtration Process

Filtration Process

  • The contaminated water enters the tank through the inlet manifold, transitioning to the Yardney 3-way valve and into the top inlet of each tank.
  • The Yardney two-stage deflector creates a uniform distribution for laminar flow across the media bed while avoiding channeling of the media bed.
  • Particulate is trapped and retained within the media bed resulting in clean process water flowing out through the stainless steel wedgewire underdrain, to the outlet of each filter tank and to the outlet manifold for end use.

  

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. 

Backwash Process

Filtration Process

Filtration Process

  • Backwash sequence is initiated by either elapsed time of the Yardney controller or pressure differential between the inlet and outlet manifolds.
  • Water or air pressure opens the Yardney 3-way valve causing the reverse flow of a portion of filtered water up through the stainless steel underdrain to hydraulically and uniformly lift the media bed.
  • The use of a hydraulically balanced underdrain in conjunction with a gravel pack creates a proper and uniform lift of the media bed while avoiding a turbulent backwash.
  • Particulate is released during the backwash event, exhausted through the backwash manifold and routed to a convenient location.
  • One tank at a time is backwashed while continuing to process water for use until the entire system is clean.
  • Once completed with the backwash, filtration continues until the next backwash event is called for.


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.
