Composite Pressure Tanks
swtwater.com Cyclonic Distributor System™ (CDS)
Cutaway photo of tank showing Cyclonic Distribuor System bottom plate and mid plate construction.  
The Cyclonic Distributor System (CDS) is an innovative vessel technology providing higher flow rates, less pressure loss, improved treatment capacity, product flexibility, and water conservation. Simply put—Smart technology. The CDS creates uniform water distribution in both service and regeneration flow paths to better utilize media surface area and depth, which extends the contaminant removal capacity of the media and subsequently requires less regeneration. Mid plates are available to compartmentalize several different media in a single vessel—eliminating the need for multiple tank systems, reducing system costs, and providing easier installations and servicability.
 
BENEFITS:
Conserves water
Softeners require less salt
30% less backwashing
Increased resin capacity of 10 to 15% compared to standard basket distribution systems
Permanent attachment of the riser tube and distribution plates eliminates rebedding when servicing the valve
100% corrosion-free
Reduces environmental impact
Creates cleaner, more efficient water treatment systems
 
Compare Standard Basket Distributor Flow Paths to the Cyclonic Distributor System™
             
Standard Service illustration   Cyclonic Service illustration   Standard Backwash illustration   Cyclonic Backwash illustration
Standard Service
leaves 'dead zones' of
unused media in the
bed and promotes
channeling.
  Cyclonic Service
utilizes the entire
media bed.
  Standard Backwash
lifts the bed.
  Cyclonic Backwash
utilizes angled plate
slots to expand the
full bed and swirl
the media, resulting in
a more vigorous and
effective cleaning of
the entire media bed.
