Receiving

1
Slurry Carb Reactor
Dryer

• Receiving

Centrifuge
Storage
2
Biosolids Receiving

• Basic Equipment
• Receiving Hopper/Scale
• Screw conveyors
• Pumps
• Rationale for Design
• Allows for Efficient biosolids receiving with
  minimal vehicle idling
• Allows for 33-38 delivery truck per day of
  biosolids per EIR

3
Biosolids Storage

• Basic Equipment
• Two (2) 1200 ton biosolids storage silos
• Rationale for Design
• Storage capacity equivalent to 3 to 5 days of
  biosolids feed materials for operation
• Allows for continuous operations eliminating
  costly and energy intensive start-ups and shut
  downs
• Storage capacity greater than 1 day of Facility
  Peak Daily Tonnage of 1,080 wet tons per day

4
SlurryCarb Process

• Basic Equipment
• Heaters
• SlurryCarb reactor
• Rationale for Design
• Heater will pre-heat slurry solution (biosolids)
  and Reactor carbonizes biosolids
• Original heater and reactor capacity expected to
  be approximately 675 wet tons per day of slurry
  solution at a 28 solids content. Engineering
  study revealed optimum capacity of heater and
  reactor to be 825 wet tons per day of slurry
  solution at a 28 solids content.

5
Centrifuge (Dewatering)

• Basic Equipment
• Centrifuge feed tank
• Polymer feed tank
• Rationale for Design
• Necessary to separate solids and liquids prior to
  drying
• Centrifuge sized for a feed rate of 1,080 wet
  tons per day of slurry solution at 14 average
  solids content

6
Dryer

• Basic Equipment
• Standard dryer utilizing
• natural gas, flue gas, biogas for heating
• Rationale for Design
• Dryer design based on an initial estimated
  projected energy demands. However, based on
  engineering study it was determined that
  the dryer was more efficient and able to process
  more slurry solution per day than initially
  estimated.
