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
Up to 40% less pressure drop through the system
Spin-welded plate to inner bottom dome designed to handle over 6500 lbs. of force and differential pressure
No gravel underbed saves on overall cost and unit weight
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.
             
 
CDS VS. STANDARD BASKET DISTRIBUTORS
(Comparing tanks with one cubic foot of 10 percent resin.)
CDS Tank Standard Tank
Bed expansion in backwash 10.5 inches of lift Bed expansion in backwash 5 inches of lift
Time to lift bed to full expansion
at 2.0 gpm = 2.0 minutes
Time to lift bed to full expansion
at 2.0 gpm = 4.25 minutes
Four minute backwash time = 8.0 gal. Eight minute backwash time = 16.0 gal.
Fast rinse reduced from six to two minutes
at 2.0 gpm = 4.0 gal.
Fast rinse had to stay at six minutes
at 2.0 gpm = 12.0 gal.
 
BACKWASH TESTING RESULTS OF A 16x65 CDS CARBON SYSTEM
"Sweet Spot" for backwash is 5.76 gpm/sq.ft.
Standard specification is 8 to 10 gpm.
Volume savings and fluidization time with full expansion of bed is less than 2 minutes.
CDS backwashes for 7 to 8 minutes (compared to typical carbon filters of 14 minutes or more).
 
CDS THIRD-PARTY VALIDATION AND TESTING RESULTS
(WQA/NSF 44 comparison testing of a one cubic foot softener)
Capacity Test @ 4.5 lbs. of salt
Standard tank with gravel = 3472 grains
CDS = 4333 grains
Increase of 25%
 
All CDS pressure vessels are wound fiberglass composite tanks with copolymer polypropylene liner and are NSF® listed. 100% made in USA.
