3. What is Adsorption Clarification?
Adsorption clarification is an upflow process using bouyant media for high rate clarification.
Features:
AC can replace conventional flocculation and settling.
Similar to Deep Bed filtration.
Operates at % of nominal flow rate.
Pretreatment addition to existing filters.
Media can be floated out for tank inspection.
PAC addition creates an excellent adsorption contactor for taste and odor removal.
No reversal of flow needed. Clarification and cleaning are both up flow.
Quick start up, no sludge blanket required.
A DeepBed filter is a granular filter typically with a 4 foot media depth at a filtration rate of more than 2 gpm/ft2. Coarse media is normally used to encourage deep penetration of solids into the media bed. This allows for longer filtration runtimes.
Poly-aluminium chloride (PAC) is an inorganic coagulant

AC Media Technical Details:
Buoyant Media
Specific gravity slightly < 1.0
Allows for complete fluidization
Effective size ~2.5 mm
Patented rolled and scarified media offers superior performance
NSF 61 available
Competitive advantage
Lasts for life of plant
No maintenance required

7. Adsorption Clarifier Technology
AC replaces conventional flocculation and settling
Coagulated material is flocculated by mixing that occurs in the tortuous path through the AC media
This material is removed by adsorption onto the AC media surface
Settling not a factor
AC units operate at % of nominal flow rates
AC media can be floated out for inspection
PAC addition creates an excellent adsorption contactor for taste and odor removal
Extremely low maintenance

21 second video clip, shows and explains the clarifier flush operation.

9. AC High Flow Rate Reduces Footprint
5 to 15 GPM/FT2
Footprint < 10% Of Conventional Clarifier

10. Adsorption Clarifier Performance
Proper conditioning of raw water provides turbidity removals across AC from 70 % to 90 %, typical
AC typically cleans 2 to 4 times per every filter backwash
