Description

The Captivator®​ System improves a conventional anaerobic process by capturing and converting BOD to biogas that otherwise requires aeration energy. The system utilizes a VLR® Contact Tank to help biomass maximize the absorption of soluble BOD. A Folded Flow® DAF applied to the liquid stream removes and thickens the majority of biomass and incoming sludge at high overflow rates.

Features

Features

  • VLR® Aerated Contact Tank helps biomass absorb both soluble and colloidal BOD. Low energy disc aeration is incorporated into a space efficient design.
  • Folded Flow DAF efficiently removes and thickens the majority of the biomass and incoming SS, eliminates considerable footprint and capital costs, reduces grit sent to the digester and related maintenance costs.
  • Integrated Control System fine tunes performance of the system, provides seamless controls across technologies and eliminates unnecessary PLC’s.
