PRIMARY & SECONDARY CLARIFIERS

CLARIFIERS ARE THE PRINCIPLE MECHANISMS FOR SOLID /LIQUID SEPARATION IN PRIMARY, INTERMEDIATE AND FINAL WASTEWATER CLARIFICATION APPLICATIONS

SPS MANUFACTURES MANY TYPES OF CLARIFIER MECHANISMS TO BEST SUIT THE CLARIFICATION PROCESSES.

STEEL SHELLS AND TANKS ARE ALSO AVAILABLE.

THE MOST WIDELY USED CLARIFIERS ARE DEPICTED BELOW FOR GENERAL INFORMATION.

Available in sizes 0-200ft diameter

PRIMARY CLARIFIERS

TYPE I & II SEDIMENTATION

PRIMARY PURPOSE:

  • Remove solids that pass through headworks and grit equipment.
  • Lessen organic loading on following biological process
  • Buffer flow and load stabilization to secondary process / split stream treatments.

SECONDARY CLARIFIERS

TYPE I, II, III & IV SEDMENTATION

PRIMARY PURPOSE:

  • Separate and remove solids/biomass produced in biological process in manner that suits process goals (rapid sludge removal, detention time, etc.).
  • Thicken solids for recirculation and process reuse.
  • Store biomass as buffer to prevent process upsets.
