UltraCell

UltraCell combines MBBR and ultra filtration processes without a need for a secondary clarifier or a DAF to remove bulk of the TSS.  Typically, a biological treatment system is followed by a secondary solids separation process and a tertiary filtration step to produce reuse quality water.  Headworks has developed the UltraCell product with an extensive pilot study of its MBBR process with a ceramic membrane (ultrafiltration).  Due to the very low TSS in the MBBR process relative to the membrane bioreactor (MBR), the UltraCell process requires minimal power and cleaning chemicals.  Moreover, the flux rate through the membrane is increased by a factor of 4, thereby quadrupling the lifetime of the membranes.  The overall capital and operating costs of the UltraCell process are significantly lower than the MBR process, while the footprint of both processes is approximately the same.

  • Features + Benefits
  • Photos
  • MBBR followed by ceramic membranes maintains separate biological and membrane unit processes, allowing for maximum total system performance
  • Each process is individually controlled and optimized to provide an integrated solution
  • MBBR effluent suspended solids exhibit low membrane fouling
  • Membrane separation of solids from MBBR exit stream produces very high-quality effluent of BOD and TSS <2 mg/L each that is suitable for reuse applications
  • The low solids directly increases the membrane flux, resulting in high recovery rates
  • UltraCell can tolerate moderate peak flow rates and load fluctuations
  • Can treat challenging water (high turbidity, TSS, oily water, warm water, algae blooms, peak demand) without extensive pre-treatment
  • Use Active Cake Layer Filtration (ACLF) for additional removal of dissolved compounds and color with Powdered Activated Carbon
  • No performance decay or fiber breakages like polymeric membranes
